delivered the Opinion of the Court.
¶1 Donald Rogers (Rogers) appeals from the judgment and sentence entered by the Eleventh Judicial District Court, Flathead County, on a jury verdict finding him guilty of sexual intercourse without consent. We affirm in part and reverse in part.
¶2 We restate the issues on appeal as follows:
¶3 1. Did the District Court abuse its discretion in admitting testimony by the emergency room physician?
¶4 2. Did the District Court abuse its discretion in admitting testimony about previous sexual assaults by Rogers?
BACKGROUND
¶5 On May 29,1997, Rogers met Kristian Gale (Gale) at the Blue Moon Saloon, near Columbia Falls, Montana, where each had gone to enjoy the live music. They talked, had drinks and danced. Gale declined Rogers’ advances throughout the evening, and they left the bar in separate vehicles sometime after midnight. After following Gale for a time, Rogers pulled his pickup in front of her Bronco and stopped. Rogers then approached Gale’s vehicle.
¶6 According to Gale, her vehicle had stalled when Rogers cut her off and, when he reached her, he grabbed her arm and her keys and threatened to hurt her if she did not do what he asked. Rogers told Gale to get in his truck, but she refused, saying, “If you’re gonna do this, do it in my truck.” Gale then suggested she move her vehicle off the roadway and, with Rogers reaching in through the window and holding onto the steering wheel, she did so. Rogers directed her to disrobe and get in the back seat, and she did. According to Gale, while in the back of her vehicle, Rogers grabbed her hair, pushed her head into his crotch and forced her to perform oral sex on him. He subsequently pulled her head up and began kissing her and penetrating her vagina *190 with his finger. As Rogers was about to engage in sexual intercourse with her, Gale asked him to use a condom. He replied he had no diseases and proceeded with intercourse.
¶7 Gale left the vehicle to relieve herself and, when she returned, Rogers was in the front seat of her vehicle. Gale joined Rogers in the front seat and each had a beer. Rogers talked about having been in prison for drug problems and not wanting to go back; Gale consoled him, suggesting he ask for help “from above.” Rogers asked if Gale would like to have sex again. She declined, but asked for his phone number in case she changed her mind. Gale drove Rogers the short distance back to his pickup.
¶8 As Rogers got out of Gale’s vehicle, he told her that, if she intended to call the police, she should run over him right then. Gale said she was not going to call the police and drove home. She called a friend in Seattle to discuss the incident and told her friend she was reluctant to report the incident because no one would believe her. Her friend convinced her otherwise and she called law enforcement. Flathead County Sheriff’s Deputy Gordon Barthel met with Gale and she related what had occurred, describing the location of the incident, Rogers’ vehicle and Rogers, including his name. Another deputy took Gale to the emergency room at Kalispell Regional Hospital, where Dr. James Dusing, the emergency room physician, examined her and found two “hickeys” on her neck and a tear in her labia.
¶9 The State of Montana (State) subsequently charged Rogers by information with sexual intercourse without consent, a felony. His first trial ended in a mistrial.
¶ 10 At Rogers’ second trial, the State’s case focused on Gale’s flight attendant training in dealing with hostage situations, where she was taught to submit to demands and negotiate to stay alive. Gale testified she felt threatened during the incident with Rogers, even though she did not see a weapon, so she applied her training to the situation. Dr. Dusing testified, over Rogers’ objection, that Gale’s emotional state in the emergency room was consistent with what he had observed in other patients who reported being raped. The District Court also admitted, over Rogers’ objection, testimony from two women, Angela Tretteen (Tretteen) and Janice Lee Auwen (Auwen), regarding prior acts of sexual assault by Rogers against them. Rogers admitted having sexual intercourse with Gale, but claimed she was a willing participant. The jury found Rogers guilty of sexual intercourse *191 without consent and the District Court subsequently sentenced him and entered judgment. Rogers appeals.
STANDARD OF REVIEW
¶11 Trial courts have broad discretion in determining whether evidence is relevant and admissible, and we will not overturn a trial court’s evidentiary ruling on appeal absent an abuse of that discretion.
State v. Smith,
DISCUSSION
¶12 1. Did the District Court abuse its discretion in admitting testimony by the emergency room physician?
¶ 13 Dr. Dusing treated Gale in the emergency room on the morning she reported being raped. Prior to the introduction of Dr. Dusing’s testimony at Rogers’ second trial by videotaped deposition, Rogers objected to the following direct examination testimony:
Q. Okay. You described [Gale’s] emotions as being at times angry, at other times teary eyed.
A. Uh-huh.
Q. Did any of that seem inappropriate to you?
A. No. In my experience of dealing with women who have reported to be raped, that’s very consistent. It seemed very appropriate.
Rogers asked the court to excise the testimony from the videotape on the grounds it was opinion testimony for which he did not “think a foundation [had] been laid.” Without specifying whether Dr. Dusing was offering an opinion at all or, if so, whether it was expert or lay opinion testimony, the District Court overruled the objection and admitted the entire videotaped testimony. The court observed that Dr. Dusing had been an emergency room physician for more than 12 years, during which time he would have been exposed to people who reported being raped, and concluded that that experience provided foundation for Dr. Dusing to report whether or not Gale’s demeanor was consistent with what he had observed in his experience.
¶ 14 Rogers contends the District Court abused its discretion in admitting the testimony because the State failed to lay a proper foundation of special training or experience to qualify Dr. Dusing as an expert in Rape Trauma Syndrome (RTS) and because Dr. Dusing testified to the ultimate issue of whether Gale was raped and to her credibility. The State *192 responds that Dr. Dusing did not testify regarding RTS and, therefore, it was unnecessary to lay a foundation qualifying him as an expert in RTS. In addition, the State contends Dr. Dusing’s testimony did not encompass the ultimate issue or Gale’s credibility because it was limited to his observations and experience within his own practice.
¶15 RTS is a post-traumatic stress disorder which persons subject to severe trauma such as rape may experience.
State v. Liddell
(1984),
¶ 16 In support of his contention that Dr. Dusing testified to the ultimate issue and to Gale’s credibility, Rogers asserts the District Court allowed Dr. Dusing “to tell the jury that Gale’s behavior meant that she was telling the truth about being raped.” Rogers over characterizes Dr. Dusing’s testimony.
¶17 When asked if Gale’s emotions as he had previously described them — at times angry, at other times teary eyed — seemed inappropriate to him, Dr. Dusing merely stated that “[i]n [his] experience of dealing with women who have reported to be raped, that’s very consistent. It seemed very appropriate.” The testimony did not characterize Gale’s emotions as having any particular meaning, much less state that Gale was telling the truth about being raped. It merely compared Gale’s emotional state with that of other women in Dr. Dusing’s experience who had reported being raped.
¶18 The general rule is well established that an expert may not comment on the credibility of an alleged victim.
See State v. Stringer
(1995),
¶ 19 We hold the District Court did not abuse its discretion in admitting Dr. Dusing’s testimony.
¶20 2. Did the District Court abuse its discretion in admitting testimony about previous sexual assaults by Rogers?
¶21 Prior to trial, the State notified Rogers of its intent to introduce evidence of other crimes, wrongs or acts and Rogers filed a motion in limine to prohibit the State from doing so. The District Court denied Rogers’ motion and admitted the State’s other acts evidence via testimony by Tretteen and Auwen regarding past sexual assaults by Rogers.
¶22 Tretteen testified that Rogers sexually assaulted her in September of 1995. She worked for Rogers’ parents and considered Rogers a friend. After tending bar one night, she interrupted a fight between Rogers and his mother and asked Rogers to go for a drive. Rogers drove down a country road, stopped and made advances toward Tretteen. When she asked him to stop, he pulled out a gun and told her they were going to have intercourse. When Tretteen responded she would rather die first, Rogers fired the gun out the window and then pointed it at her. Tretteen continued to argue and plead with him to take her home. Tretteen eventually escaped and hid until he quit looking for her. Rogers subsequently was charged with attempted sexual intercourse without consent and felony assault, and convicted of felony assault.
¶23 Auwen testified that Rogers sexually assaulted her in May of 1997. She knew Rogers’ mother and talked with Rogers in a bar one night. She subsequently left the bar and drove a short distance out of town, where one of her vehicle’s tires went flat. Rogers and a friend stopped to help and, after they changed the tire, Rogers gave his friend Auwen’s keys to return her car to town. Auwen went with Rogers, who drove her through town and into a wooded area where he pulled her clothes off, called her a “bitch,” and told her if she did not behave herself she would end up dead. She testified that, although Rogers did not threaten her with a gun, she saw a gun on the floor of his truck as he pulled her hair to force her to engage in oral and sexual intercourse with him. After the assault, Rogers drove her back to her car. She reported the *194 incident to the Missoula County Sheriff’s Department, but did not pursue it.
¶24 Rogers contends that, because the only issue in his case was whether or not Gale consented to intercourse with him, Tretteen and Auwen’s testimony was not admissible other acts evidence under Rule 404(b), M.R.Evid., or this Court’s decisions. Therefore, according to Rogers, the District Court abused its discretion in admitting the evidence.
¶25 Rule 404(b), M.R.Evid., generally prohibits the use of other acts evidence to prove a person’s character in order to show that he or she acted in conformity with that character at the time in question. The Rule also provides, however, that other acts evidence may be admissible for certain other purposes. We have established relatively strict criteria for the admissibility of such evidence, however:
(1) The other crimes, wrongs or acts must be similar.
(2) The other crimes, wrongs or acts must not be remote in time.
(3) The evidence of other crimes, wrongs or acts is not admissible to prove the character of a person in order to show that he acted in conformity with such character; but may be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.
(4) Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, misleading of the jury, considerations of undue delay, waste of time, or needless presentation of cumulative evidence.
State
v. Matt
(1991),
¶26 With regard to the first Modified
Just
Rule criterion, Rogers relies on
State v. Hansen
(1980),
¶27 There, the prosecution’s evidence was that the defendant met the alleged victim in a bar, they left together, he drove into an isolated area and, when she resisted his advances, he twisted her thumb against her wrist and engaged in intercourse with her.
Hansen,
¶28 The defendant appealed the admission of evidence of the earlier sexual assault and we applied the four-part
Just
test, the first prong of which was identical to that later set forth in the Modified
Just
Rule.
Cf. State v. Just
(1979),
¶29 We then surveyed — and were persuaded by — holdings from other jurisdictions which recognized that, when the alleged similarities between crimes are nothing more than a sequence of events common to the crime, they are not sufficiently distinctive to satisfy the similarity element for admissibility of other acts evidence.
Hansen,
¶30 We reach the same conclusion here. Tretteen and Auwen’s testimony regarding prior sexual assaults on them by Rogers, as well as Gale’s testimony about the incident which formed the basis for the charge in this case reflected the general barroom pickup scenario described in Hansen: spend time together in a bar, enter a vehicle together in a remote location or subsequently drive to a remote location, advances, resistance and forced sexual assault or intercourse. As was the case in Hansen, the sequences of events related by Tretteen and Auwen do not contain distinctive qualities that distinguish them *196 from numerous other incidents resulting in sexual intercourse without consent so as to meet the similarity criterion of the Modified Just Rule.
¶31 The State does not advance an analysis of the similarity element pursuant to
Hansen.
It argues
Hansen
has been cited by other courts as consistent with the rule that, without “distinctive qualities,” the prior acts evidence is insufficient to establish a “modus operandi,” and simply operates as evidence of a propensity to commit the offense which Rule 404(b), M.R.Evid., prohibits.
See, e.g., Idaho v. Martin
(1990),
¶32 It is true that, in
Hansen,
we also considered the similarities of the other crimes evidence in the context of whether a modus operandi existed.
Hansen,
¶33 The State also attempts to analogize the facts in the present case to
State v. Wurtz
(1981),
¶34 The same cannot be said here. As discussed above, the sequences of events to which Tretteen and Auwen testified — while similar to each other and to the events at issue — do not contain distinctive qualities distinguishing them from numerous other incidents resulting in sexual intercourse without consent. Therefore, pursuant to Hansen, we conclude the State’s other acts evidence in this case does not meet the similarity criterion of the Modified Just Rule.
¶35 With regard to the third Modified Just Rule criterion, Rogers urges that the District Court erred in determining that the other acts evidence tended to establish motive, intent, plan or common scheme because consent was the only issue at trial. The State responds that Rogers’ “prior acts show a conscious object to accomplish a goal, and a willingness to use any degree of threat or force to achieve that goal.” Thus, according to the State, the challenged evidence shows a “motive, intent, plan, or modus operandi to obtain sex by means of threats and violence.”
¶36 We rejected an argument similar to that advanced by the State regarding motive and intent in
State v. Keys
(1993),
¶37 Moreover, as was the case in
Keys,
the determinative issue in the present case is Gale’s intent — that is, whether she consented to intercourse — rather than Rogers’ intent or motive.
See Keys,
¶38 With regard to the District Court’s determination that “the similarities are ... probative of the Defendant’s ... plan or common scheme,” Rogers contends primarily that the District Court’s plan or common scheme rationale for admissibility merely equated acts the court considered similar in nature to satisfaction of the narrower concept of common scheme or plan. He relies on cases such as
State v. Harris
(Wash. Ct. App. 1984),
¶39 Under the Modified
Just
Rule test, it is clear that similarity of the other acts evidence which may satisfy the first element of the test is not sufficient to meet the third element, which requires that other acts evidence constitute proof of a defendant’s common scheme or plan. In making the common scheme or plan determination, we conduct a case-by-case analysis of the defendant’s actions. In
State v. Brooks
(1993),
the plan was nonetheless systematic in that swimming or water games were used as a prelude to the assaults, and the boys were each in a vulnerable position because they wore fewer clothes while they were swimming, or in G.M.’s case, receiving a back rub, than they would have in a more formal setting.
Brooks,
¶40 In
Hansen,
on the other hand, we concluded that the conduct did not suggest a common scheme or plan, relying on an earlier case where we held evidence of a prior sexual act inadmissible, stating “ ‘[sjexual acts, whether rape or no rape, originating in barroom pickups, powered by the urge, and consummated in automobiles, are entirely too common in this day and age to have much evidentiary value in showing a systematic scheme or plan.’
’’ Hansen,
¶41 As discussed above and similar to Hansen, the other acts evidence in the present case, as well as the events underlying the offense charged, fit into the basic scenario of a barroom pickup leading to intercourse or attempted intercourse and an accusation that the events were nonconsensual. Moreover, the genesis of the events involving Tretteen, Auwen and Gale was substantially different. Tretteen asked Rogers to go for a drive and they left together. Auwen left the bar alone and experienced a flat tire on her vehicle; Rogers and a friend had left the bar together, happened upon her and changed the tire. In the present case, Gale left the bar alone, Rogers followed her and then drove in *200 front of her vehicle, cutting her off. Thus, while later events in all three cases bore some similarities, the manner in which the three incidents began simply does not tend to establish a common scheme or plan by Rogers under our cases. Indeed, the other acts evidence in this case, as in Brown, suggests only that Rogers will spontaneously take advantage of opportunities that present themselves for sexual encounters with women. In other words, Rogers’ acts of sexual aggression are dictated by his character and the situation at hand; they do not reflect a systematic plan as in Brooks.
¶42 We conclude that the State’s other acts evidence was not admissible to prove motive, intent, plan or common scheme under the third element of the Modified
Just
Rule. Moreover, the evidence was not relevant to the only issue in this case — whether or not the intercourse between Rogers and Gale was consensual. Therefore, the only purpose for the evidence was to prove Rogers’ character and that he acted in conformity with his character on the night in question. Rule 404(b) expressly prohibits the admission of other acts evidence for that purpose.
See
Rule 404(b),
M.R.Evid.; Matt,
¶43 The State’s other acts evidence having failed to satisfy the first and third elements of the Modified Just Rule, we need not address the fourth element. We hold that the District Court abused its discretion in admitting testimony about previous sexual assaults by Rogers.
¶44 Affirmed in part and reversed in part.
