Opinion

TAYLOR, Justice.

After a deadly ear accident claimed the life of Charles Pennington and left Eric Mintun seriously injured, with no recollection of the accident or prior events, Eric Mintun was charged with aggravated homicide by vehicle in violation of Wyo. Stat. § 6 — 2—106(b)(i) (1997). Both Charles Pennington and Eric Mintun were ejected from the vehicle during the accident; thus, the only issue at trial was who was driving the car when it crashed. The jury determined Eric Mintun was driving, leading to a guilty verdict. We affirm.

I.ISSUES

Appellant, Eric L. Mintun (Mintun), raises four issues:

ISSUE I.
Was the Appellant denied a fair trial when the court allowed the admission of a computerized recreation of the accident into evidence over objection?
ISSUE II.
Was the Appellant denied a fair trial when the State had a second expert witness give cumulative testimony for the purpose of bolstering the credibility of its main witness, Sergeant Kourbelas?
ISSUE III.
Was the Appellant denied a fair trial as guaranteed by the due process clauses of the United States and Wyoming Constitutions because of prosecutorial misconduct during the closing argument?
ISSUE IV.
Was the Appellant denied a fair trial when the trial court allowed the State’s expert witness to impeach the Appellant’s expert witness before he testified?

The State phrases the issues as:

I. Did the district court properly admit a computer animation of the automobile crash that killed the victim?
II. Did the district court err in permitting the State’s expert witness, John Kwasnoski, to testify over Appellant’s objection that the testimony was cumulative?
III. Did counsel for the State commit prosecutorial misconduct in closing argument?
*957 IV. Did the district court properly permit the State’s expert witness, during the State’s case-in-chief, to comment upon the conclusions made by Appellant’s expert witness in his oral pretrial report?

II. FACTS

After a night of heavy drinking, Mintun and two of his friends, Charles Pennington (Pennington) and Brian Chapman (Chapman), decided to go hunting. Around 5:00 a.m. on October 8, 1995, the three friends stopped at Mintun’s home where he traded his pickup for his girlfriend’s car. They left Mintun’s home with Mintun driving, Chapman in the back seat, and Pennington asleep in the front passenger’s seat. A few minutes later, they stopped at the home of one of Chapman’s friends, Charlotte Mudd. Concerned that the men were too intoxicated to hunt safely, Ms. Mudd tried to persuade them to stay at her home and “sleep it off.” Making perhaps the wisest decision of his life, Chapman agreed to stay. Mintun became angry at Chapman, and drove off “like a bat out of hell.” Pennington remained asleep in the ear during this visit to Ms. Mudd’s residence, and was still sleeping when they left.

Sometime prior to 7:20 a.m., the car failed to negotiate a curve. Traveling at approximately forty miles per hour, the car jumped the curb, struck a street sign, and collided with a light pole. The ear rolled and turned, eventually coming to a stop on its top and facing the direction from which it had come. Both Pennington and Mintun were ejected from the ear, with Mintun landing in the street and Pennington next to the car’s final stopping place. Pennington died at the scene and Mintun sustained serious life-threatening injuries. Police were notified of the crash at 7:20 a.m., and arrived shortly thereafter.

Sergeant Neil Kourbelas investigated the accident. None of those who stopped to assist had seen the crash occur and Mintun’s injuries left him unable to recall the accident. 1 Thus, Sergeant Kourbelas had no witness accounts of how the crash occurred or who was driving. Using his education and experience in accident reconstruction, Sergeant Kourbelas attempted to reconstruct the accident from the evidence he collected at the site, coming to the conclusion that Min-tun had been driving.

At trial, Sergeant Kourbelas testified as to his investigation and reconstruction of the accident. The State also presented John Kwasnoski (Kwasnoski), a physics professor who also specializes in accident reconstruction. Using Sergeant Kourbelas’ investigation results and his own personal observation Of the damaged vehicle, Kwasnoski did his own reconstruction of the accident. He too came to the conclusion that Mintun had been driving. Kwasnoski testified that his reconstruction depended upon mathematical computations and the laws of physics, differing from Sergeant Kourbelas’ reconstruction which was based upon experience. Over Mintun’s objection, Kwasnoski was also allowed to compare his conclusions with those of Milo Beaver (Beaver), the expert hired by Mintun. Although Mintun’s expert had not yet testified, Kwasnoski refuted the conclusions Beaver had stated prior to trial.

The State also offered the testimony of Nathaniel Huff (Huff), an eyewitness to the accident who did not come forward until shortly before trial. Huff explained his location at the time of the accident, and related his version of what had occurred. Huff testified that he saw Mintun ejected from the vehicle. Huffs calculation of Mintun’s point of ejection was the same point at which Kwasnoski had calculated Mintun’s ejection was most likely. However, Huff also testified that Mintun was ejected from the passenger’s side of the car, and that he had seen Pennington gripping the steering wheel while the accident was in progress.

Finally, the State used a computer-generated video animation of the accident as a demonstrative exhibit during Sergeant Kourbelas’ testimony. The animation showed the accident from three different vantage points: a top, or helicopter, view; a *958 side view; and what was termed the witness view. Marvin Larsen, the animator responsible for this exhibit’s creation, testified he used measurements and other information provided by Sergeant Kourbelas, and the animation was intended to present Sergeant Kourbelas’ reconstruction of the accident from the three different vantage points. Sergeant Kourbelas affirmed this intent, and specifically testified the “witness view” was intended to present what he believed an eyewitness would have seen from Huffs vantage point, not what Huff claimed to have actually seen. The witness view was inconsistent with Huffs testimony, showing the car spinning before Mintun was ejected. Sergeant Kourbelas explained his theory that, although Huff accurately placed the point and time of ejection, Mintun was actually ejected from the driver’s side after the car had spun around.

In his defense, Mintun called Beaver, a mechanical engineer who is also an accident reconstructionist. Beaver testified he used Sergeant Kourbelas’ investigation results along with his own measurements and observations of the vehicle and accident site in reconstructing the accident.
