OPINION
Robert Ralph Stahle appeals four convictions for indecency with a child and one conviction for aggravated sexual assault. Appellant pleaded guilty to the indecency charges and not guilty to the aggravated sexual assault charge. After finding appellant guilty in all five eases, the jury assessed punishment at twenty years’ confinement in each indecency case and life imprisonment in the aggravated sexual assault case. In ten points of error, appellant contends the trial judge erred in (1) admitting evidence of extraneous offenses during trial, (2) failing to suppress oral and written statements made by appellant during custodial interrogation, (3) not requiring the State to elect the particular acts of sexual contact it would rely on at trial, and (4) failing to quash the indictments. In two additional points of error, appellant contends the evidence is legally and factually insufficient to support his convictions. For the reasons set forth below, we affirm the trial court’s judgments.
Background
On August 18, 1995, appellant appeared at the Plano police station and spoke to Plano police detective Michael Johnson. During the course of the videotaped interview, appellant told Johnson that, seven or eight years before, he had fondled his six or seven year old niece in the living room of his home. According to appellant, there were a number of other people in the room at the time and, as best as he could recall, the fondling occurred on only several occasions over the period of a few days. 1 Appellant told John *686 son he decided to come to police after discussing the problem with his therapist and deciding he “wanted to take care of it.” During the course of the conversation, appellant also told Johnson about a similar incident that occurred a year or so after the incident with his niece. This incident, according to appellant, involved a six or seven year old girl from appellant’s neighborhood. Appellant told Johnson the fondling occurred approximately five or six times over a period of a year to a year and a half. Appellant described the fondling of both girls as “just toueh[ing]” inside and outside the clothing, but not any sort of penetration. During the interview, appellant told Johnson there were no similar incidents with other girls. Following the interview, appellant wrote and signed a written statement summarizing the events he had just described. Thereafter, appellant left the police station.
After meeting with appellant, Johnson began an investigation. Later, on September 5, 1995, appellant contacted Johnson again and told him he wanted to talk. When appellant returned to the station, Johnson conducted a second videotaped interview with appellant. This time, appellant told Johnson that he realized, after further counseling, that he had in fact engaged in some additional, inappropriate behavior with two other seven or eight year old girls. Appellant told Johnson the instances again involved appellant touching the girls’ genitals, but this time outside their clothing. Again, following his discussions with Johnson, appellant wrote and signed a written statement detailing the events he had just described.
After meeting with appellant the second time, Johnson continued his investigation. Following that investigation, Johnson called appellant and asked him to come back to the station. Appellant did so and, on September 12, 1995, Johnson conducted a third videotaped interview with appellant. During this interview, appellant reiterated to Johnson that while he touched the girls inappropriately, he did not penetrate any of them. Following this interview, appellant again wrote and signed a written statement. During trial, all three statements were admitted into evidence before the jury. The third written statement was admitted only at punishment, not at guilt/innocence. Shortly after the third interview, on September 30, 1995,- appellant was arrested for aggravated sexual assault and indecency with a child.
In June 1996, appellant pleaded guilty before the jury to the indecency with ¿ child charges and not guilty to two aggravated sexual assault charges. During the joint trial that followed, the State presented testimony from twelve witnesses, including the five complainants (C.T., R.B., A.S., N.T., and D.T.). After hearing from these witnesses, the jury found appellant guilty of four counts of indecency with a child and one count of aggravated sexual assault. The jury later assessed punishment in each case. These appeals followed.
Sufficiency of the Evidence
In his ninth and tenth points of error, appellant contends the evidence is legally and factually insufficient to support his convictions. Under these points, appellant contends we must reverse his convictions because the State presented no evidence or, alternatively, insufficient evidence to show appellant knowingly committed aggravated sexual assault or indecency with a child. After reviewing the record in these causes, we cannot agree.
When reviewing a challenge to the legal sufficiency of the evidence, we view the evidence in the light most, favorable to the verdict.
Turner v. State,
By contrast, in conducting a factual sufficiency review, we examine the jury’s weighing of the evidence.
See Clewis v. State,
Aggravated Sexual Assault
A person commits the offense of aggravated sexual assault if he intentionally or knowingly causes the penetration of the female sexual organ of a child and the child is younger than fourteen years of age.

Under the penal code, a person acts knowingly or with knowledge with respect to the nature of his conduct when he is aware of the nature of the conduct. Tex. Penal Code Ann. § 6.03(b) (Vernon 1994). Knowledge may be inferred from an accused’s acts, words, and conduct.
See Martinez v. State,
In this case, appellant contends the evidence is legally and factually insufficient to show he knowingly committed aggravated sexual assault against C.T. After reviewing the record in this cause, we cannot agree. We note initially that the charge in this case authorized the jury to convict appellant if it found either that he committed the aggravated sexual assault knowingly or intentionally. On appeal, appellant has not challenged the sufficiency of the evidence to support a finding that appellant committed the offense in this case intentionally. Because the court’s charge authorized a conviction based on a finding of intentionally and appellant has not challenged that finding on appeal, we conclude we need not address appellant’s ninth point of error because our disposition of that point would have no effect on appellant’s conviction.
Nevertheless, we conclude, after reviewing the entire record in this case, that the evidence was legally and factually sufficient to support appellant’s conviction. During trial, C.T. repeatedly testified that, while visiting appellant and his family at appellant’s home, appellant would ask her to sit on his lap, under a blanket, and then he would “stick his finger in [her] vagina.” On further questioning by the prosecutor, C.T. testified she knew appellant was sticking his finger inside her because she “could feel it” and “it hurt.” C.T.’s father corroborated much of C.T.’s testimony, noting that when he confronted appellant about C.T.’s allegations, appellant admitted “put[ting] his finger inside of C.T.” 2
*688
We conclude, after reviewing this evidence in the light most favorable to the verdict, that any rational jury could have found beyond a reasonable doubt that (1) appellant, as a grown adult, was aware of the nature of his conduct; and (2) appellant therefore caused the penetration of C.T.’s sexual organ knowingly. Accordingly, we conclude the evidence is legally sufficient to sustain appellant’s conviction for aggravated sexual assault. We likewise conclude, after reviewing all the evidence presented at trial, that the jury’s finding was not so against the great weight of the evidence as to be clearly wrong and manifestly unjust. Although appellant repeatedly told Johnson that he did not penetrate any of the girls, C.T. testified to the contrary, noting that, during the incidents, appellant “put his finger
inside
[her].” The jury was entitled to believe C.T.’s testimony and disbelieve appellant’s statements to Johnson.
See Clewis,
Indecency with a Child
In felony cases, a plea of guilty before the jury admits the existence of all elements necessary to establish guilt and, in such cases, the introduction of evidence by the State is only to enable the jury to intelligently determine punishment.
See Holland v. State,
Here, appellant pleaded guilty before the jury to the indecency charges, and these causes were submitted to the jury on punishment. As noted above, appellant’s pleas of guilty admitted the existence of all elements of the charged offenses, and appellant neither withdrew nor attempted to withdraw those pleas during trial. Nor has appellant challenged the voluntariness of those pleas on appeal. Because appellant pleaded guilty to the charged offenses before the jury, we conclude (1) the State was not required to present any evidence to support appellant’s convictions, and (2) appellant may not now challenge the sufficiency of the evidence to support those convictions.
See Ex parte Williams,
EXTRANEOUS OFFENSES
In his first, second, third, fourth, and fifth points of error, appellant contends the trial judge erred in admitting into evidence certain extraneous offenses allegedly committed by appellant against the five complainants. According to appellant, admission of these extraneous offenses was improper because (1) the evidence was not relevant to any issue at trial, and (2) any probative value associated with the evidence was substantially outweighed by the danger of unfair prejudice. Additionally, appellant contends-in his sixth point of error that we must reverse his convictions because the “cumulative effect” of the trial court’s error in admitting, the complained-of evidence was “overly prejudicial” to him. After reviewing the record in these *689 causes, we cannot agree with appellant on any of these points.
Article 38.37 of the Texas Code of Criminal Procedure states, in pertinent part, that:
Notwithstanding Rules 404 and 405, Texas Rules of Criminal Evidence, evidence of other crimes, wrongs, or acts committed by the defendant against the child who is the victim of the alleged offense shall be admitted for its bearing on relevant matters, including:
(1) the state of mind of the defendant and the child; and
(2) the previous and subsequent relationship between the defendant and 'the child.
Tex.Code Crim. Proc. Ann. art. 38.37, § 2 (Vernon Pamph.1998) (emphasis added). Article 38.37 applies to prosecutions for sexual offenses committed against a child under seventeen years of age.
Id.
§ 1. By enacting article 38.37, the legislature in effect determined that, in certain 'sexual abuse cases, evidence of “other crimes, wrongs, or acts” committed by the accused against the child victim are relevant and admissible under rule 402 (and notwithstanding rules 404 and 405).
See Hinds v. State,
Under the language of article 38.37, evidence of extraneous crimes, wrongs, or acts committed by the appellant against one child victim are admissible in a case involving that child victim. We conclude the complained-of evidence in these cases meets this requirement (at least with respect to the admission of extraneous offenses relating to one child victim in the case involving that child victim) because the evidence involves additional, uncharged acts of improper fondling by appellant against the child victims. Because - the complained-of evidence meets the requirements for admission under article 38.37, we conclude (at least with respect to the admission of extraneous offenses against the same child victim) that the evidence was properly admitted. We likewise conclude, after reviewing the record as a whole, that the probative value of the evidence (at least as it relates to the same child victim) was not substantially outweighed by the danger of unfair prejudice. Tex.R.Crim. Evid. 403. Accordingly, we conclude the trial judge did not err in admitting evidence of extraneous offenses against one child victim in the case involving that child victim. 4
This does not, however, end our inquiry. We must still decide whether the admission of extraneous offenses against one child victim was properly admitted in the cases involving the remaining child victims. Under the circumstances presented in these cases, we conclude that it was. As noted above, the cases against appellant were consolidated for trial and, from the record before us, it does not appear appellant objected to the trial judge’s decision to consolidate the cases. The failure to object to a consolidation of cases either before or during trial constitutes an implied consent to the consolidation.
See Milligan v. State,
For the reasons stated, we overrule appellant’s first, second, third, fourth, and fifth points of error. Having found no error in *690 the trial judge’s decision to admit the subject evidence at trial, we likewise reject the argument in appellant’s sixth point of error that the “cumulative effect” of the trial judge’s error requires reversal. We overrule the sixth point of error.
ORAL' AND WRITTEN STATEMENTS
In his seventh and eighth points of error, appellant contends the trial judge erred in failing to suppress the oral and written statements he made to Johnson prior to his arrest. According to appellant, these statements should have been suppressed because (1) they were the product of custodial interrogation, and (2) he did not receive proper warnings prior to making the statements. After reviewing the record in these causes, we cannot agree.
Article 38.22 of the code of criminal procedure sets out certain requirements for admitting an accused’s oral and written statements when those statements are made as a result of custodial interrogation.
See
Tex.Code Crim. Proc. Ann. art. 38.22 (Vernon 1979 & Pamph.1998). Article 38.22 specifically excludes from its requirements any statement that does not stem from custodial interrogation.
See
Tex.Code Crim. Proc. Ann. art. 38.22, § 5 (Vernon 1979) (noting that nothing in article “precludes the admission of ... a statement that does not stem from custodial interrogation”). “Custodial interrogation” is defined as “questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way.”
See Miranda v. Arizona,
A person need not be under formal arrest to be considered subject to custodial interrogation.
See Melton v. State,
The court of criminal appeals has outlined at least four general situations which may constitute custody for purposes of article 38.22:(1) when a suspect is physically deprived of his freedom of action in any significant way; (2) when a law enforcement officer tells a suspect he cannot leave; (3) when law enforcement officers create a situation that would lead a reasonable person to believe his freedom of movement has been significantly restricted; and (4) when probable cause to arrest exists and law enforcement officers do not tell the suspect he is free to leave.
See Dowthitt,
931 S.W.2d at
*691
255 (citing
Shiflet v. State,
We have reviewed the record in these causes and, after doing so, we conclude (1) appellant was not in custody at the time he gave his oral and written statements, and (2) those statements were therefore not subject to the requirements of article 38.22. In this ease, appellant voluntarily appeared at the Plano police station on four separate occasions to talk to Johnson. The first time, appellant appeared at the station unannounced, but Johnson was not present, and appellant was asked to return the following day. Appellant returned the following day of his own volition and indicated a desire to tell his story to Johnson. Before being contacted by appellant, the police were completely unaware of any criminal activity involving appellant. In addition, during the course of the conversation between appellant and Johnson, Johnson told appellant he was free to leave the interview at any time. According to Johnson, the door to the interview room remained open throughout the interview, and it in fact “was never locked.” Following the first videotaped interview, appellant was allowed to leave the station.
Several weeks later, on September 5th, appellant again contacted Johnson of his own volition and indicated a desire to talk further. During this interview, Johnson read appellant his Miranda rights and appellant then voluntarily disclosed additional, incriminating information to Johnson. However, during the interview, Johnson again told appellant he was free to leave, and appellant did in fact leave the station following the interview. Then, on September 12th, Johnson contacted appellant and asked him to return to the station. According to Johnson, he “asked [appellant] if he would be willing to come back down and talk to [him],” and appellant agreed. 6 Once at the station, Johnson again read appellant his Miranda rights and appellant engaged in another discussion with Johnson. During that discussion, appellant made reference to having an attorney, and Johnson told appellant that Johnson could not talk to him anymore and appellant needed to leave. According to Johnson, appellant refused to leave, saying he did not want to talk to a lawyer. At that point, Johnson again assured appellant that the door was open and he was free to leave at any time. Appellant did in fact leave the station once the third interview was concluded.
It appears from the record that, despite Johnson’s repeated assurances that appellant was free to terminate the interviews, appellant chose to remain at the station and discuss the allegations involved in these cases at length. Johnson testified at the suppression hearing that appellant was not under arrest during any of the interviews. On ail three occasions, appellant ultimately wrote and signed written statements about the offenses. Although these statements appear to have been written at Johnson’s suggestion, nothing in the record shows that appellant’s free
*692
dom of action was in any way hampered before, during, or after he agreed to execute the statements.
See Wicker v. State,
Under these circumstances and in light of the reasonable person standard set out in
Stansbury
and
Dowthitt,
we conclude appellant was not in custody for purposes of article 38.22 at the time the oral and written statements were made. Contrary to appellants contentions, the fact that (1) Johnson considered appellant to
be
a suspect at the time of the statements, and (2) appellant was the focus of the investigation during those statements, does not conclusively establish “custody” for purposes of article 38.22.
See Stansbury, 511 U.S.
at 322-26,
We note additionally that although appellant also contends the statements should have been suppressed because they included inadmissible extraneous offenses that were not relevant and whose probative value, if any, was substantially outweighed by the danger of unfair prejudice, we need not address this argument at least with respect to the first two written statements and the three oral statements because we have previously concluded that the extraneous offenses discussed in those statements were properly admitted by the trial court during guilt/innocence. With respect to the extraneous offenses included in the third written statement admitted at punishment, we conclude we need not address this point because it has not been adequately briefed.
Rule 38.1(h) of the rules of appellate procedure requires an appellant to include in his brief a “clear and concise argument for the contentions made, with appropriate citations to authorities and to the record.” Tex. R.App. P. 38.1(h). Here, appellant made only a conclusory statement in his brief that the third written statement was objectionable because it included extraneous offenses that were (1) not relevant, (2) barred by limitations, and (3) so remote that their probative value was substantially outweighed by their danger of unfair prejudice. Other than fleeting references to rules 402, 403, and 404(b) of the rules of criminal evidence, appellant provides no discussion or analysis of relevant authorities or the record to support his argument. Under these circumstances, we cannot conclude this point has been adequately preserved for our review. See
Menchaca v. State,
We reach a similar conclusion with respect to appellant’s passing suggestion that his third oral and written statements were also objectionable because they were made after appellant invoked his right to counsel. Again, appellant provides no discussion or analysis of the effect, if any, of his invocation of his right to counsel, no citation to the record, and no reference to any legal authorities other than the Sixth Amendment to the United States Constitution. Under these circumstances, we conclude appellant has failed to adequately brief his argument. See
Menchaca,
For the reasons stated, we overrule appellant’s seventh and eighth points of error.
Election
In his eleventh point of error, appellant contends the trial judge erred in not requiring the State to elect the particular acts of *693 sexual contact it would rely on to support the convictions in these cases. For the reasons set forth below, we overrule appellant’s eleventh point of error.
When the evidence shows two or more acts of sexual contact, each of which is an offense for which the defendant may be convicted, and the indictment charges only one offense, the State is required to elect which act it will rely on to secure a conviction, provided the accused makes a motion for election.
See Scoggan v. State,
Nevertheless, we note two additional arguments made by appellant under this point: (1) appellant contends his constitutional right to be indicted by a grand jury was violated because there was no showing the acts designated by the State were the same acts presented to the grand jury in these cases; and (2) appellant contends the indictments in these cases were not sufficiently certain to protect him from being twice placed in jeopardy for the same offense. With respect to the first point, we note that the court of criminal appeals recently addressed this precise argument in
Sledge v. State,
We reach a similar conclusion with respect to appellant’s argument that the indictments in these cases, because they alleged only an “on or about” date, failed to adequately protect him from being twice placed in jeopardy for the same offense. As the court of criminal appeals recently recognized in
Ex parte Goodbread,
*694 For the reasons stated, we overrule appellant’s eleventh point of error.
Motions to Quash
In his twelfth point of error, appellant contends the trial judge erred in denying his motions to quash the indictments in these cases. According to appellant, failing to quash the indictments violated his right to due process of law because the indictments, by alleging the offenses were committed “on or about” a certain date, failed to give him adequate notice of the particular acts charged against him. We disagree.
We note initially that with respect to appellant’s convictions in the indecency cases, appellant has waived any error associated with the denial of his motions to quash. The law in this State is well settled that a guilty plea entered without benefit of a plea bargain waives all nonjurisdictional defects occurring prior to entry of the plea.
See Helms v. State,
Turning to appellant’s complaint about the denial of his motion to quash in the aggravated sexual assault ease, we note that the State need not allege a specific date in an indictment.
See Sledge,
Here, the indictment alleged that appellant committed the offense of aggravated sexual assault “on or about” August 1, 1989. This allegation put appellant on notice that he must be prepared to defend against proof showing he committed the offense at any time prior to presentment of the indictment and within the applicable statute of limitations.
See Thomas,
We affirm the trial court’s judgments.
Notes
. Appellant told Johnson the situation recently came to light during a conversation his niece (C.T.) had with her grandmother about the possibility of C.T. moving into appellant's home. According to appellant, C.T.’s father came to appellant shortly after C.T.’s disclosure, and appellant admitted to him that C.T.'s allegations were true and that he was "very ashamed of the situation.”
. C.T.’s father specifically testified as follows:
[Appellant] said he had done something that he wasn’t proud of and I asked him what, and *688 he said he had fondled [C.T.], and I said, that he put his finger inside of her, and he said, I guess I did.
(Emphasis added.)
. We note additionally that although appellant contends under this point that the evidence was legally and factually insufficient to support his conviction for indecency with C.T., a review of the record indicates appellant was not convicted of indecency in the case involving. C.T.;, his conviction in that case was for aggravated sexual assault, and we have previously concluded the evidence was sufficient to support that conviction.
. We note additionally that although appellant pleaded guilty to the indecency charges before the jury (and thus relieved the State of any burden to produce evidence in those cases), the State was nevertheless entitled to produce evidence in those cases if it so desired.
See Bagley v. State,
. Although the court of criminal appeals has in the past recognized four factors as being relevant to the custody determination
(i.e.,
probable cause to arrest, subjective intent of police, focus of investigation, and Subjective belief of defendant), the United States Supreme Court has since held that the second and fourth factors are irrelevant except to the extent they may be manifested in the words or actions of law enforcement officials.
See Dowthitt,
. Although appellant’s wife testified at the suppression hearing that (1) she and her husband had only eight minutes to get to the station or Johnson said they would both be arrested, and (2) they therefore did not believe they had any choice but to go to the station, Johnson disputed this testimony during the hearing. The trial judge was the factfinder at the suppression hearing and, as such, was entitled to believe Johnson’s testimony and disbelieve the testimony from appellant’s wife.
See Green v. State,
. We note additionally, as did the Fort Worth court in
Sledge,
that while article 21.04 of the code of criminal procedure requires an indictment to be sufficiently certain to enable an accused to plead the judgment in bar of a further prosecution,
see
Tex.Code Crim. Proc. Ann. art. 21.04 (Vernon 1989), case law in this State has attempted to balance the due process interests of those accused of committing crimes against children against the interest of the State in prosecut
*694
ing cases involving child victims.
See Sledge v. State,
. Although appellant again argues under this point that the "on or about” language was improper because it prevented him from pleading the judgments in these cases in bar of a subsequent prosecution, we have already addressed this argument in connection with point of error eleven.
