Opmmn by
11 Defendant, Robert Juan Gee, appeals .the Judgment of conv1ct10n entered on jury verdicts finding him guflty of first degree assault, first degree burglary, and aggravated robbery. He also appeals the sentence imposed and the trial court's order denying his motion for a new trial.
T2 Gee contends that the trial court erred in (1) admitting evidence that he fled to Michigan while awaiting trial; (2) adjudgmg him a habitual criminal; (8) denying his request for an extended proportionality review of his sentence; and (4) denying his motion for a new trial. We address and reject each of these contentions and affirm.
I. Facts and Procedural History
13 Gee's codefendant, Lamar Wilson, testified at Gee's trial that he, Gee, and Maurice *718 Ray went to the victim's apartment with the intent to rob him of money and drugs. According to Wilson's trial testimony, Gee and Ray had planned the robbery, and they all had guns: Gee and Ray had 9 mm handguns, and Wilson had a .22 caliber revolver.
14 Wilson testified that Gee knocked on the victim's door, the victim opened the door, and then he tried to close it again. Wilson said that Gee then fired one shot through the door, went inside, and asked where the money and "dope" were. He heard Gee say, "Do you want to die?" and then he heard several more shots. He testified that, after leaving the apartment, Gee said, "I think he's dead."
T5 The victim testified that earlier that day, he had gone to the bank and cashed his paycheck for $818, That night, when he returned to his apartment complex, he saw two people behind him as he was approaching his apartment. After he opened the door to his apartment, he heard a shot.
16 The victim testified that one of the assailants wore a black coat with fur fringe and the other wore a hooded sweatshirt, They both had masks and guns. He testified that he tried to shut the door, but it would not close all the way. This was the last thing he remembered before the police came and he was taken to the hospital. He had been shot five times.
T7 A woman who lived near the victim testified that she was watching television when she heard gunshots. She cracked her door open and saw three people running in the victim's apartment building, They wore black "hoodies" 'and white masks. She closed her door and called 911. '
1] 8 The building manager for an apartment complex adjacent to the victim's building also testified that he heard gunshots. He then 'saw three people come out of the front entryway of the victim's apartment complex. They were wearing dark clothing with their hoods pulled down to cover their faces and their hands were in their pockets. He saw them get into a waiting sports utility vehicle (SUV)-it was running and its lights were on-and he noticed part of its license plate number before it drove away. When the police arrived, he gave them a description of the SUV and the partial Heense plate number, and he told them the direction in. which the car had headed. .
"T9 The police located the SUV and arrested the four occupants (Gee, Wilson, Ray, and the driver, Melissa Robinson). The police found a 9 mm handgun on the floor next to the front passenger seat where Gee had been sitting. Forensm testing established that it was the gun used‘to shoot the victim,
{10 In the SUV, the police also found three masks, two dark-colored. hooded sweatshirts, and a black Jacket with fur fringe on the hood with Gee's. wallet in the pocket, $844 was found in Wilson's pants pocket.
T11 Gunshot residue (GSR) testing revealed GSR on both of Ray's hands and on his face, on Wilson's face, and on both of Gee's hands and on his face.
[ 12 Wilson pleaded guilty to one count of aggravated robbery with a stipulated sentence of four to sixteen years' imprisonment. As part of his plea agreement, he agreed to testify at Gee's trial, Ray was tried separately and did not testify at his trial or at Gee's. He was convicted of first degree burglary and received a lengthy sentence,
T 18 Clee was charged with various offenses including attempted first degree murder (after deliberation). He did not testify: The jury acquitted him of attempted first degree murder but convicted him .of first degree assault with a deadly weapon under section 18-3-202(1)(a), C.R.S8. 2015; first degree burglary as a crime of violence under sections 18-4-202(1) and 18-1.3-406(@)(a)(D(A), C.R.S. 2015; and aggravated robbery with a deadly weapon under section 18—4—302(1)(b), C.R.S8. 2015.
(14 The trial court found that all three convictions were for crimes of violence. The court also found that the prosecution had proved beyond a reasonable doubt that Gee had two prior felony convictions and sentenced him as a habitual criminal under seetion 18-1.3-801(L.5)(a), C.R.S8. 2015. Based on these findings, the court sentenced Gee to 'A8 years' imprisonment for each conviction, to be served consecutlvely, for an aggregate term of 144 years. ° -
*719 € 15 Shortly after sentencing, Gee filed a motion for a new trial under Crim. P. 88(c) claiming newly discovered evidence. The trial court denied the motion.
II. Evidence of Flight
16 After his arrest, Gee was released on bond. On January 12, 2011, he appeared at the preliminary hearing, which was continued to February 2.
117 Also on January 12, Robinson, Gee's girlfriend, had an interview with the district attorney and the police concerning her knowledge about the crime. She apparently provided information that incriminated Gee. Robinson's statement was given to the defense within a few weeks of the interview.
1 18 Gee failed to appear at the February 2 preliminary hearing, and a warrant was issued for his arrest. Four months later, Gee was located in Michigan and returned to Colorado for trial. C
€ 19 On the third day of trial, the prosecutor told the trial court that he intended to call the district attorney's office investigator to testify. The investigator had assisted in locating Gee. The prosecutor stated that the investigator's testimony would establish evi-denee of flight, which he asserted was admissible to show Gee's consciousness of guilt.
(20 Defense counsel objected, arguing that such evidence falls under CRE 404(b) and the prosecution had not provided pretrial notice of its intent to introduce the evidence. The trial court overruled the objection, stating that evidence of Gee's flight was not CRE 404(h) evidence and that it was relevant and admissible to show Gee's mental state in fleeing the jurisdiction.
{21 The investigator testified regarding Gee's failure to appear at the February 2 hearing, the issuance of the arrest warrant, and locating Gee:
122 Gee argues that the trial court erred in admitting this testimony because he contends that evidence of flight to show consciousness of guilt is admissible only under CRE 404(b), defense counsel had requested disclosure of CRE 404(b) evidence pretrial, and the prosecution did not provide timely notice of its intent to introduce the evidence. We reject this argument.
123 We review a trial court's decision to admit evidence for an abuse of discretion. People v. Perry,
1 24 CRE 404(b) prohibits the admission of "Lelvidence of other crimes, wrongs, or acts ... to prove the character of a person in order to show that he acted in conformity therewith." Such evidence may be admissible for other purposes "provided that upon request by the accused, the prosecution in a criminal case ... provide[s] reasonable notice in advance of trial ..; of the general nature of any such evidence it intends to introduce at trial." Id.
~, 125 Gee argues that evidence that he fied to Michigan constituted evidence that he violated section 18-8-212(1), C.R,8.2015, which provides that a knowing violation of bail bond conditions or a knowing failure to appear for trial or other proceedings is a class 6 felony. Gee contends that because this evidence constituted evidence of other crimes, it was subject to CRE 404(b).,
126 "Evidence of a defendant's flight may be relevant to show consciousness of guilt, ..." Perry,
*720
127 CRE 404(b) generally governs evidence of a defendant's other crimes or bad acts that are extrinsic to the events charged. See People v. Cooper,
128 Res gestae evidence is "[elvi-dence of other offenses or acts that is not extrinsic to the offense charged, but rather, is part of the criminal episode or transaction with which the defendant is charged." Quintana,
29 A division of this court has concluded that the res gestae of an offense. includes "Lelvidence of a defendant's behavior, including threats against witnesses or nonwitness-es, [that] may be admissible to show that the defendant was conscious of guilt and, by further inference, committed the charged." People v. Kyle,
It is the general rule that evidence of offenses other than the one for which the defendant is on trial is not admissible. But where the case is such that proof of one crime tends to prove any fact material in the trial of a person accused of another crime, such proof is admissible.... [The defendant's] conduct leading to his arrest was a cireumstance properly brought to the attention of the jury ... for the purpose of determining whether such conduct tended to show or not show his consciousness of guilt.
Id. at 842,
1830 Colorado cases addressing evidence of flight have analyzed the issue under principles of relevancy, but they have not directly held that such evidence is not subject to CRE 404(b). Based on the principles discussed above, we now hold that evidence of Gee's flight was integrally linked to the criminal transaction for which he was charged, constituted res gestae evidence, and was not subject to the requirements of CRE 404(b). See Quintana,
{ 31 Gee cites Medina,
132 In Medina,
[ 33 Under this second line of cases, an act "somewhat remote in time" from the charged crime nevertheless is res gestac if the two are "inextricably intertwined" such that the former "forms an integral and natural part of an account of the crime." Fears,
184 There is a persuasive argument that evidence of flight is neither CRE 404(b) evidence nor res gestae; rather, such evidence is directly relevant to the charged offense as tending to show consciousness of guilt, See, e.g., Howard v. State,
135 However, as we read the relevant cases from the Colorado Supreme Court, evidence indicating that a defendant committed an uncharged erime is either CRE 404(b) or res gestae evidence. See People v. Rollins,
1 36 Accordingly, the trial court did not err in admitting evidence of Gee's flight to Michigan. ' oe
III, Sentencing Issues
A. Relevant Facts
T37 Gee was convicted of three class 3 felonies. § 18-8-202(2)(b) (first degree assault); § 18-4-202(2) (first degree burglary); §.18-4-802(8) (aggravated robbery). . The presumptive sentencing range for a class 8 felony is four to twelve years' imprisonment. § 18-1.3-401(1)(@)(V)(4), C.R.98.2015, All three crimes also constituted crimes of violence. Gee's first degree assault and aggravated robbery convictions were per se crimes of violence. § 18-8-202(2)(c) (first degree assault); § 18-4-302(4) (aggravated robbery); People v. Hunsaker,
1 88 The legislature has deemed crimes of violence "extraordinary risk" crimes, and "for such crimes which constitute class 3 felonies, the maximum sentence in the presumptive range shall be increased .by four years." §.18-1.3-401(10)(a), (b)(XIID). Accordingly, the maximum sentence in the presumptive range for each of Gee's three con-viections was sixteen years.
T 89 Gee was also charged with two habitual criminal. counts. At the habitual criminal proceeding, the prosecution introduced «evidence that in March 2001, Gee pleaded guilty to possession of a schedule II controlled substance, a class 4 felony at the time. The prosecution also introduced evidence that in *722 June 2005, Gee pleaded guilty to conspiracy to distribute a schedule II controlled substance, a class 8 felony at the time.
1 40 The trial court adjudged Gee a habitual criminal and sentenced him under section 18-1.3-801(1.5), which provides:
[Ejvery person convicted in this state of any class 1, 2, 8, 4, or 5 felony ..: who, within ten years of the date of the commission of the said offense, has been twice previously convicted ... of a felony ... shall be adjudged an habitual criminal and shall be punished ... by imprisonment in the department of corrections for a term of three times the maximum of the presumptive range pursuant to section 18-1.8-401 for the class or level of felony of which such person is convicted. ...
(Emphasis added.) Accordingly, the trial court sentenced Gee to forty-eight years' imprisonment for each offense.
[41 Because all three convictions were for crimes of violence, the trial court also imposed consecutive sentences undér section 18-1.3-406(1)(a), which provides that "[a] person convicted of two or more separate crimes of violence arising out of the same incident shall be sentenced for uch crimes so that sentences are served consecutlvely rather than concurrently."
B. Habitual Criminal Finding
4 42 Gee argues that the trial court erroneously found that the conspiracy conviction qualified as a predicate offense for the habitual criminal sentence because, even though he was an adult when he was convicted, he was a Juvenile for most of the date range charged. ° (Gee was born on October 6, 1982, and the date range charged was between and including September 1, 1997, and May 10, 2002.) Gee contends that under the rationale of United States Supreme Court precedents, particularly Graham v. Florida,
148 We agree with the People that Gee did not preserve this contention 'of error. At Gee's sentencing hearing, as part of an argument not renewed on appeal, defense counsel maintained that Gee committed the acts underlying the conspiracy in 1997, before he was eighteen, but the prosecution delayed prosecution until 2002. Counsel cited Bostelman v. People,
T44 The trial court concluded that the plain language of the habitual eriminal statute foreclosed this argument because it addresses "convictions" entered within ten years of the charged offense. The court found that Gee pleaded guilty to the conspiracy charge when he was twenty-three years old and noted that he was twenty at the end of the date range charged. The court thus determined that the conspiracy conviction qualified as a predicate offense.
"45 To preserve an argument for appeal, "the trial court must be presented with an adequate opportunity to make findings of fact and conclusions of law on [the] issue." People v. Melendez,
146 The argument made in the trial court did not present the court with an opportunity to rule on the argument Gee makes on ap *723 peal: an Eighth Amendment challenge based on the imposition of a de facto sentence of life without parole. Gee thus did not preserve this argument, and we review for plain error. See id.
47 "Plain error must be both obvious and substantial, and we will not vacate a sentence for plain error unless the error so undermined the fundamental fairness of the sentencing proceeding as to cast serious doubt on the reliability of the sentence." People v. Alvarado,
48 In Graham,
T 49 A division of this court applied Graham to a juvenile nonhomicide offender's sentence for a term of years that was, as here, the functional equivalent of a life sentence without parole. People v. Rainer,
150 However, Gee's sentence was not based on acts that he committed solely as a juvenile; rather, it was also based on acts he committed while he was an adult. "Conspiracy is a continuing course of conduct which terminates when the erime or crimes which are its object are committed or the agreement that they be committed is abandoned by the defendant and by those with whom he conspired." § 18-2-204(1), C.R.S. 2015. ,
151 Gee turned eighteen in October of 2000. The indictment charging Gee alleged that he conspired to distribute a controlled substance from 1997 until 2002. Significantly, the indictment also alleged specific acts involving selling and distributing a controlled substance that Gee committed after his eighteenth birthday. By pleading guilty, Gee admitted these allegations, including that he committed the discrete acts alleged in the indictment. See United States v. Broce,
52 Gee's conspiracy conviction was therefore an adult conviction for acts committed by Gee when he was an adult. Thus, we need not, and do not, address whether the rationale of Grgkam and Rainer would apply when a conviction constituting a predicate offense for a habitual criminal sentence is based solely on crimes committed by a defendant when he or she was a juvenile.
[58 Accordingly, we reject Gee's argument that the trial court erred in sentencing him as a habitual eriminal.
C. Propbrtionality Review
154 Gee filed a presentence motion requesting that the trial court conduct an extended proportionality review. The court conducted an abbreviated proportionality review, concluding that all five crimes-the three triggering offenses and the two predicate offenses-that formed the basis of his habitual criminal sentence were grave and serious. The court thus did not conduct an extended proportionality review.
155 Gee now argues that the court erred in denying his request for an extended proportionality review. We disagree.
$56 We review de novo a trial court's proportionality determinations. People v. Gaskins,
*724
157 The ' Eighth Amendment prohibits "cruel and unusual punishments," which the United States Supreme Court has interpreted to include sentences that are grossly disproportionate to the severity of the crimes committed. See People v. Mershon,
158 When conducting-an abbreviated proportionality review of a habitual criminal sentence, a reviewing court seruti-nizes the offenses in question to determine "whether in combination they are so lacking in gravity or seriousness so as to suggest that the sentence is grossly disproportionate." People v. Deroulet,
€59 The Colorado Supreme Court has designated certain offenses as per se grave or serious, which means that they are grave or serious "by their very nature." People v. Gaskins,
160 Aggravated robbery and burglary are per se grave or serious because, by their nature, they "involve violence or potential for violence." Gaskins,
T61 Gee does not dlspute that his convictions for aggravated robbery, burglary, nar-coties distribution, and, first degree assault were for grave or serious offenses. He also concedes that current supreme court precedent holds that nareotics-related offenses are per se grave or serious. See, e.g., Deroulet,
1K 62 Nevertheless, Gee argues that because Colorado's public policy regarding narcotics possession (as evinced by legislative amendments) has changed in recent years, whether a conviction for possession of a controlled substance is per se grave, or serious or may support a habitual eriminal sentence is no longer clear. He thus contends that, in determining whether his possession convietion was grave or serlous, we should follow other divisions of this court that have considered subsequent legislatlve chariges reducing the classification and sentence for possession, See, e.g., Hargrove, ¶¶ 19-20; People v. Anaya,
T 63 However, we need not demde whether it is appropriate to do so, or even whether Gee's possession conviction was grave or serious, because even were we to assume that it was not grave or serious, we would conclude *725 that his sentence was not unconstltutlonahty disproportionate. >
164" For proportionality review purposes, at legst outside of the juvenile offender context, "[where 'the erime of violence statute requires the imposition of consecutive sentences, a reviewing court must conduct an abbreviated proportionality 'review of each separate sentence and cannot consider the total cumulative sentence." Deroulet,
165 Each of Gee's forty-eight-year sentences was supported by at least two convictions for grave or serious crimes (the triggering conviction and the conspiracy to distribute conviction) and a third felony conviction (the possession conviction). We conclude that considering the three offenses sup- / porting each sentence together, they are not so lacking in gravity or seriousness so as to raise an inference that the forty-eight year sentences are grossly disproportionate.
$166 Because none of the imposed. sentences raise an inference of gross. dispro-portionality, the trial court did not err in denying Gee's request for an extended proportionality review. -
IV. Motion for a New Trial
167 After sentencing, Gee moved for a new trial under Crim. P. 88(c) based on newly discovered evidence.. As grounds, Gee stated that both Wilson and, Ray had recently made statements that exeulpated him..
€68 In an affidavit submitted with the motion, Ray stated that Wilson had planned the crime without Gee's involvement and Wilson had shot the victim while Ray was present. Ray stated that Gee never got out of the vehicle and was not involved in the shooting. .
169 In another affidawt Gee's 1nvest1ga-tor, who had interviewed Wilson, stated that Wilson said that he was pressured by the district attorney to. implicate Gee to satisfy his plea agreement. According to the investigator, Wilson said that he was outside of the victim's apartment when the shooting occurred and could not see into the apartment. or any of the individuals involved,; and thus he did. not actually see Gee shoot the victim.
T70 The trial court denied the motion without a hearing. The court's primary basis for concluding that neither Ray's nor Wilson's statements provided a sufficient basis for a new trial was: that, even if it assumed that the statements constituted newly discovered evidence, they probably would not produce an acquittal on retrial.
T 71 The court explamed that Wllson s new statement was only partially (if at all) at odds with his prior testimony; as he had not explicitly testified that he had seen the shooting, nor was he asked at trial about, his vantage point. © Regarding Ray's statement, the court explained that his recounting of the crime was implausible: It was inconsistent with the testimony of the two neighbors who had observed three individuals and- with .the physical evidence: GSR was found on Gee's face and hands, and the gun used to shoot the victim was found near where he was sitting in the vehlcle used to: flee the crime scene. n
172 Crim, P. 83(c) provides that the trial court "may grant a. defendant a new trial .if required in the interests of justice." We review a trial court's decision whether to grant a new trial for an abuse of discretion. People v. Munsey,
178 To succeed on a motion for a new trial based on newly discovered evidence, a defendant must show that the evidence was discovered after the trial; that the defendant and defense counsel exercised dili-genee to discover all possible evidence favorable to the defendant prior to and during the trial; that the newly discovered evidence is material to the issues involved, and not merely cumulative or impeaching; and that that the newly discovered evidence is of such character as probably to bring about an ac
*726
quittal if presented at another trial, People v. Gutierrez
T 74 For two reasons, we- conclude that the trial court did not abuse its discretion in denying Gee's motion for a new trial.
175 First, Ray's and Wilson's statements did not constitute "newly discovered" evidence. "The fact that [a codefen-dant's] testimony was not available to [al defendant at trial because [the codefendant] was unwilling to testify prior to his own trial does not make his testimony newly discovered." Gutierrez,
T76 For instance, in People v. Gallegos,
177 Gee argues that he had no indication before or during trial that Wilson and Ray would provide the postconviction statements that they did, and thus he did not know the substance of those statements. But if, as he1 e, "a defendant knew or:. should have known, that his codefendant could offer material testimony as to the defendant's role in the chal ged crime," it cannot be true, that the defendant was unaware of the codefen-dant's potential ability to exculpate him. United States v. Owen,
T78 Likewise, in Qutlerres
179 But even if we assuime that Ray's and Wilson's statements constituted "newly discovered" evidence, the trial court's determination that the evidence probably would not have resulted in an acquittal is supported by the record. In addition to the evidence the trial court discussed in its order, the police found in the SUV three masks and a Jacket with Gee's wallet in it, matching the victim's descrlptlon of what one of the assailants was wearing.' Thus, a substantial amount of evidence established Gee's participation in the crime, and the trial court's determination that the "newly discovered" evidence probably would not result in an acquittal on retrial was not an abuse of discretion. ~
*727 V. Conclusion
80 The judgment of conviction, sentence, and order denying Gee's motion for a new trial are affirmed.
Notes
. The supreme court has granted certiorari to decide "[wlhether a court, when conducting an abbreviated proportionality review of a habitrial criminal sentence, can consider the general assembly's subsequent reclassification of a crime." Rutter v. People, No. 13SC523,
. A majority of federal circuit courts of appeals have reached the same or a similar conclusion, holding that "when a defendant is aware that his codefendant could provide exculpatory testimony but is unable to obtain that testimony because the codefendant invokes his privilege against self-incrimination prior to and during the trial, the codefendant's postconviction statement exculpating the defendant is not 'newly discovered evidence,'" United States v. Owen,
