Fоllowing a jury trial, appellant, Humberto Sanchez-Rengifo, was convicted of the following offenses: (1) first-degree burglary while armed (D.C.Code §§ 22-1801(a), -3202 (1981)); (2) threats to injure a person (D.C.Code § 22-2307 (1981)); (3) second-degree child sexual abuse while armed (D.C.Code §§ 22-4109, 4120(a)(6), -3202 (1981)); and (4) three counts of first-degree child sexual abuse while armed (D.C.Code §§ 22-4108, -3202 (1981)). 1 The court sentenced appellant to *353 six concurrent terms of imprisonment as follows: life without parole for each count of first-degree child sexual abuse while armed; fifteen years to life for second-degree child sexual abuse while armed; fifteen years to life for first-degree burglary while armed; and six years and eight months to twenty years for threats to injure a person. On appeal, he argues that the Double Jeopardy Clause of the Constitution bars separate convictions for the three counts of first-degree child sexual abuse while armed and second-degree child sexual abuse while armed because the conduct involved was a part of one continuous course of action, and therefore, these offenses merge. He also argues that the trial court erred in denying, without a hearing, his post-trial motion to vacate the convictions based on alleged ineffective assistance of his trial counsel. We hold the convictions are for separate criminal аcts for which there is no Double Jeopardy bar. We also find no error in the trial court’s denial of appellant’s motion to vacate convictions.
I.
Factual Background
The offenses occurred on June 16, 1997, the fifteenth birthday of N.V., the complaining witness. N.V. testified that on that afternoon, she was in her family’s apartment with one of her friends when she went to the door in response to a knock. She observed a man, whom she identified later as Sanchez-Rengifo, wearing a paint-splattered blue and white striped shirt and blue pants, an orange and white “Home Depot” hat, and brown paint-splattered boots. She testified that the man told her that he was there to mаke repairs in the apartment and assured her that her mother knew about the work. N.V. admitted Sanchez-Rengifo into the apartment where he looked around the apartment, including her mother’s bedroom. N.V. pointed out a problem with the bars on her bedroom window. Sanchez-Rengifo told N.V. that he would return, and left the apartment. Soon after-wards, N.V.’s friend left the apartment.
Within minutes, Sanchez-Rengifo returned, and N.V. let him in. N.V. was talking on the telephone at the time, and Sanchez-Rengifo asked her to end the conversation so that they could talk about the repairs. N.V. complied, walked into her mother’s bedroom, and as she turned around, she saw thаt Sanchez-Rengifo was holding a knife. He warned her that he would kill her if she made any noise. He then ordered her to sit on her mother’s bed and to remove her clothes, which she did. For the next two hours approximately, Sanchez-Rengifo forced N.V. to engage in various sexual acts. 2
II.
Sanchez-Rengifo argues that his convictions for first and second-degree child sexual abuse while armed merge because the criminal conduct involved constitutes one continuous sexual assault. Therefore, he contends, the convictions of these offenses under the circumstances violate the Double Jeopardy Clause of the Constitution. The government argues that there is no Double Jeopardy bar to the convictions because the indictment charged four sepa *354 rate and distinct acts of criminal conduct which were submitted separately for consideration by the jury, and the evidence dispelled the claim that the various sexual assaults constituted a continuous course of conduct resulting in only one criminal violation.
A. Applicable Legal Principles
We review a claim of merger of convictions
de novo “
‘to determine whether there has been a violation of the Double Jeopardy Clause of the Fifth Amendment to the Constitution of the United States.’ ”
Maddox v. United States,
In determining whether multiple convictiоns are constitutionally permissible for criminal conduct which violates two distinct statutory provisions, absent a clearly contrary legislative intent, we apply the
Blockburger
test. (Lindbergh)
Byrd, supra
note 3,
On the other hand, “a fact-based approach remains appropriate where a defendant is convicted of two violations of the same statute.”
Morris v. United States,
Three of the convictions involved in Sanchez-Rengifo’s challenge are for violations of D.C.Code §§ 22-4108, -3202 (first-degree child sexual abuse while aimed), and the fourth is for violation of D.C.Code §§ 2-4109, -3202 (second-degree child sexual abuse while armed). 4 The term “sexual act” is defined, in pertinent part, in D.C.Code § 22-4101(8) 5 as: “(A) [t]he penetration, however slight, of the ... vulva of another by a penis; [or] (B) [cjontact between the mouth and the penis, the mouth and the vulva_” The term “sexual contact” is defined in the statute in pertinent part as “the touching with any ... body part ... of the ... breast ... of any person with an intent to abuse, ... arouse or gratify the sexual desire of any person.” D.C.Code § 22-4101(9). The indictment charges Sanchez-Rengifo with committing each of these acts described in the foregoing statutory provisions. 6
*356 B. Analysis
Sanchez-Rengifo argues that the sexual offenses involved here, like other forms of criminal assault, are considered “continuing crimes” for which multiple punishments are barred on Double Jeopardy grounds. Indeed, “[w]e have recognized that ‘[s]ome crimes by their very nature, tend to be committed in a single continuous episode rather than in a series of individually chargeable acts.’”
Gardner, supra,
In
Gray,
where a defendant challenged his rape conviction because of the court’s failure to give,
sua sponte,
a special unanimity instruction, we declined to find plain error, concluding that the short spatial and temporal separations between the attacker’s two separate acts of sexual intercourse with his victim did not convert this single episode into separate acts of rape.
7
Sanchez-Rengifo argues that the facts presented here compel the same conclusion reached' in Gray. Specifically, he points out that in this ease there was no spatial or temporal separation between the sevеral sexual acts, which all took place in the child’s mother’s bed. In fact, unlike Gray, the assaults in this case lasted approximately two hours, not minutes. During that two hour period, Sanchez-Rengifo committed against N.V. various types of sexual assaults prohibited by law, which we describe in detail to aid in the analysis of the argument.
After threatening N.V. while armed with the knife, Sanchez-Rengifo ordered her to sit on the bed and remove her shirt and bra. He sat beside her and began licking her breasts. He then told her to remove her pants, shoes and panties. Sanchezr- *357 Rengifo unzipped his pants and rubbed his penis back and forth before instructing N.V. to lay on her back. When he insеrted his penis into her vulva, she screamed in pain, and he told her to shut up and again threatened to kill her. Sanehez-Rengifo then licked her breasts again before forcing the child to perform fellatio. He also attempted to have anal intercourse with her, and when he was not successful, he ordered her to change positions so he could try vaginal penetration again. He then “stopped” and “started licking [her] vagina.” After another failed attempt to penetrate her anus with his penis, he penetrated her vulva again. N.V. testified that he held the knife toward her during each of the assaults and threatened repeаtedly to kill her. At some point after darkness fell, Sanehez-Rengifo got up to turn on the lights in the bedroom. Only the sound of N.V.’s nine-year-old brother entering the apartment allowed her the opportunity to run out of the apartment, still naked, and report the rape to her mother who was sitting on a neighbor’s porch. Sanehez-Rengifo argues that these circumstances present a continuous course of conduct which precludes punishment for more than one offense.
In addition to the temporal difference between this case and
Gray,
there is a difference between the nature of the offenses alleged.

Relying on
Gardner,
the government argues that applying the “fork in the road test” to the facts of this case, shоws that the offenses do not merge. Specifically, it contends that the facts show that Sanchez-Rengifo made an independent determination to break off one type of sexual act and begin a different course of action.
Gardner
involved an appeal from twó rape convictions in which the appellant argued that the two constituted only one offense, and therefore, one conviction must be vacated.
Similarly, in the present case, the facts show that over an extended period of time, Sanchez-Rengifo made decisions to commit different sex acts upon his victim. He “chose to satisfy a different criminal impulse by inflicting a new outrage on the complainant.”
Brown, supra,
the defendant can be said to have realized that he has come to a fork in the road, and nevertheless decides to invade a different interest, then his successive intentions make him subject to cumulative punishment, and he must be treated as accepting that risk, whether he in fact knows of it or not.
Owens, supra,
III.
Claim of Ineffective Assistance of Counsel
Sanchеz-Rengifo argues that the trial court erred in denying his motion to vacate convictions for ineffective assistance of counsel, pursuant to D.C.Code § 23-110 (1981). He contends that his trial counsel, was ineffective because he (1) failed to call or consult an independent DNA expert, and (2) failed to consult an independent fingerprint expert. The government responds that the trial court properly denied the motion because defense counsel made tactical decisions to use the government’s experts, which he did effectively, and Sanchez-Rengifo was not prejudiced.
To establish a claim of ineffective assistanсe of counsel, appellant must show: (1) that his trial counsel’s performance was deficient,
i.e.,
unreasonable under prevailing professional norms; and (2) that the deficiency resulted in prejudice to the extent that there is “a reasonable probability that but for counsel’s unprofessional errors, the result of the proceeding would have been different.”
Strickland v. Washington,
(1) Failure to Consult Independent DNA Expert
Defense counsel called the government’s expert, Alan Guisti, who testified that the primary source of the DNA on a sanitary napkin obtained from the victim after the crime was that of the victim herself. He testified that “it was not possible to make a conclusive determination as to who the other DNA donor might be.” With respect to a semen stain found on the sheet taken from N.V.’s mother’s bed, Mr. Guisti testified that the semen donor was not Sanchez-Rengifo. Sanchez-Rengifo argues that more powerful evidence could have been secured if defense counsel had secured his own expert. In support of the argument, he appended to his post-trial motion a letter written by Dr. Amanda Sozer in which she states that there was insufficient data to report that there were two sources of DNA on the napkin. In her report, she wrote: “There was no reaction with the HBGG B dot which would indicate the presence of DNA from the suspect.” Sanchez-Rengifo contends that, if provided with this evidence, the jury would have had to conсlude either: (1) that the sample was not a mixture, but came only from complainant; or (2) the sample was a mixture, but he was not the donor. 10 Such scientific evidence, he contends, would have created a reasonable doubt as to his guilt.
As the trial court found, “[t]his is not a case where defense counsel failed to analyze the DNA evidence. Instead, counsel decided to call as his own witness the expert who performed the analysis on the DNA evidence for the government, and elicited from him testimony favorable to the defense.” The trial court viewed the decision as a tactical one, as defense counsel understоod the scientific evidence and chose to utilize the favorable evidence available through government experts, rather than secure his own experts. We agree that the circumstances show that this is a case in which “the challenged action ‘might be considered sound trial strategy.’ ”
Strickland, supra,
Even assuming for the sake of argument that defense counsel’s strategy could be deemed to constitute ineffectiveness, Sanchez-Rengifo fails to show that the defense was prejudiced thereby under the
Strickland
standard.
See Kinard, supra,
(2) Failure to Call Independent Fingerprint Expert
Sanchez-Rengifo argues that the trial court erred in denying his § 23-110 motion on the grounds that his trial counsel was ineffective for failing to call or consult an independent fingerprint expert. Defense counsel called Ms. Florine Allen, the fingerprint expert of the Metropolitan Police Department, who analyzed the latent fingerprints recovered from the apartment where the crimes occurred. Ms. Allen testified that none of the latent fingerprints recovered from the [crime] scene connected [Sanchez-Rengifo] to the offense. The government elicited from the crime scene search officer, Joseph Anderson, that “there are some persons who will not leave fingerprints. We call these people nonsecreters.” Sanchez-Rengifo argues that trial counsel should have sеcured an expert to determine whether he was a “secreter.” He contends that an expert who tested him post-trial concluded that he was likely to leave a print on a smooth, receptive surface. Such evidence, Sanchez-Rengifo contends, would have prevented the government from undermining his argument that he was not the assailant because his fingerprints were not recovered from the crime scene.
Again, the argument that trial counsel was ineffective is based upon the advantage of hindsight after hearing the government’s response to the absence of fingerprint evidence at trial. The trial court concluded that the decision to use the government’s expert to show that Sanchez-Rengifo could not be connected to the crime by fingerprints after the government’s efforts to locate fingerprints, was not unreasonable under prevailing norms. We need not decide whether this strategy rose to the level of constitutional deficiency because
Strickland
prejudice has not been shown. The evidence against Sanchez-Rengifo was overwhelming, as above-described. There was evidence that San-ehez-Rengifo’s prints were not recovered from the van either, although the evidence showed that he had used it. With this evidence, the government could have still argued that prints may not be found for a person in a location where he is known to have been. Sanchez-Rengifo does not contend that an additional fingerprint expert could have identified someone else as the rapist. For all of these reasons, we conclude that Sanchez-Rengifo has not shown the requisite prejudice to prevail on this motion.

(3) Pro Se Claims of Ineffective Assistance of Counsel
Finally, Sanchezr-Rengifo argues that the trial court erred in denying, without a hearing, his
pro se
claims that “trial counsel was ineffective for failing to move to suppress tangible evidence and for failing to introduce the complainant’s 911 call.” He cоntends that the 911 call contained an initial description of the assailant that was inconsistent with, or could cast doubt upon N.V.’s testimony. He asserts, without argument, that the trial court “erred in denying a hearing on [his] claim that counsel should have filed a motion to suppressThe trial court rejected each of these claims. It concluded that “[t]rial counsel thoroughly challenged the identification evidence at trial[,]” and the record did not show the alleged inconsistency between the initial description and Sanchez-Rengifo’s physical characteristic and that there was no showing of prejudice. As to the claim based upon the suppression issue, the trial court concluded that a motion to suppress the clothing recovered from his girlfriend’s apartment on the grounds that it exceeded the scope of the search would have been futile. Trial counsel explained that he could find no grounds on which to file a suppression motion, and Sanchez-Rengifo has offered none. Prejudice cannot be shown where the motion, if filed, would not have been successful.
See Washington v. United States,
