These are the 22 witnesses and experts who testified in police officer’s murder trial

GRAND RAPIDS, MI – Nearly two dozen witnesses and experts have taken the stand during the high-profile murder trial involving a police shooting in Michigan.

Over the span of six days of the trial, the parties called 22 witnesses and experts to testify.

After nearly two weeks of testimony, the prosecution and defense attorneys rested Monday, May 5 in the murder trial of Grand Rapids police officer Christopher Schurr.

Jurors are deliberating over a second-degree murder charge against Schurr, 34, for the high-profile killing of 26-year-old Patrick Lyoya. The jury could convict Schurr on a lesser charge of voluntary manslaughter.

Schurr pulled over Lyoya’s car April 4, 2022, in a neighborhood on the city’s southeast side for having the wrong license plate. Lyoya, a Congolese refugee, soon after tried to flee on foot.

The two later struggled over the officer’s Taser before Schurr drew his handgun and shot Lyoya in the back of the head.

Testimony in the landmark murder trial wrapped up Monday with the prosecution and defense attorneys delivering closing arguments.

The people who testified included Lyoya’s friend who recorded part of the incident on his cell phone, two homeowners who witnessed portions of the scuffle, and Grand Rapids police officers who responded to Schurr’s call for help.

Kent County Prosecutor Chris Becker and Schurr’s defense team – Matt Borgula, Mark Dodge and Mikayla Hamilton – each called policing experts who offered differing opinions of whether the shooting was justified.

In a pivotal moment during the trial, Schurr took the stand. For the first time, Schurr offered some insight of what happened, from his point-of-view, that morning.

Schurr told jurors he was “running on fumes” midway through a scuffle with Lyoya. He said he feared for his life and if he didn’t shoot Lyoya, he “wasn’t going to go home.”

Here’s a look at the 22 witnesses and experts to take the stand:

Witnesses, experts for the prosecution:

David Bukuru was hanging out with Lyoya the night before he was killed. The two men, among other friends, were hanging out at Bukuru’s apartment. Lyoya told Bukuru to wake him up in the morning because he had something to do, Bukuru testified.

Aime Tuyishime was a friend of Lyoya and a passenger riding in the vehicle the morning of the shooting. Tuyishime recorded a portion of the struggle between the two men, including the moment the officer, while on top, shot Lyoya in the head.

Wayne Butler saw police lights outside of his house on Nelson Avenue and witnessed – from behind a vehicle – part of the “tussle” between Schurr and Lyoya. He went back inside his home to get his cell phone when he heard a gunshot.

Fred Hunter lived in the home on Nelson Avenue where the altercation unfolded and witnessed part of the scuffle between Schurr and Lyoya.

Zachary Batchelor is a detective sergeant with Michigan State Police who was tasked with synchronizing three video sources of the incident into one video file so it could be viewed all at once.

Jessica Beaudry is a crime scene technician with the Grand Rapids Police Department who was responsible for photographing Schurr shortly after the incident. She took photos of the officer from various angles while he was still in uniform.

Aaron Tubergen is a detective sergeant with Michigan State Police was the lead officer investigating the incident. He was responsible for reviewing 17 different video clips of the shooting.

Dr. Stephen Cohle is Kent County’s chief medical examiner who performed Lyoya’s autopsy. Dr. Cohle testified that Lyoya was shot in the back of the head with the gun likely pressed against his head based on a lack of gunshot residue around the wound.

Seth Stoughton is a professor at the University of South Carolina Joseph F. Rice School of Law. Schurr made tactical errors that put both himself and Lyoya at risk, Stoughton testified based on his expertise.

Bryan Chiles is the senior investigations engineer with Axon, the company that manufactured the Taser Schurr used prior to shooting Lyoya. Chiles examined Schurr’s Taser and testified that both of the weapon’s cartridges had been fired and missed Lyoya.

Nicholas Bloomfield is an expert on police use of force and professional policing practices. Bloomfield testified, based on his expertise, that Schurr’s decision to use deadly force was not justified.

Witnesses, experts for the defense:

Robert McFarlane is a forensic video analyst expert who was asked by the defense to synchronize three video sources of the incident. The software McFarlane used broke down the commands Schurr gave to Lyoya from the moment the traffic stop was initiated. Schurr made a total of 31 commands during the confrontation.

Timothy Johnston is a now-retired Grand Rapids police sergeant who responded to Schurr’s call for backup the morning of the shooting.

Sam Mott is a Grand Rapids police officer who responded to the scene after Schurr shot Lyoya. Schurr looked “absolutely exhausted,” Mott testified.

Nicholas Calati is a Grand Rapids police officer arrived at the scene of the traffic stop sometime after the shooting. Calati testified that Schurr was still breathing heavily and looked pale.

David Siver is a Grand Rapids police captain who trains the department’s officers in use of force. He testified that that Schurr’s escalation to deadly force was reasonable, and a reasonable officer could perform the same way in that situation.

Chad McKersie is a Grand Rapids police captain who trains the department’s officers in use or force. McKersie testified that Schurr acted reasonably in resorting to deadly force when Lyoya took hold of his Taser.

Jason Gady is a Grand Rapids police officer who trains the department’s officers in firearms and use of force. Gady testified that Schurr was not unreasonable when he shot Lyoya in the back of the head.

Lon Bartel is the director of training and curriculum for VirTra, a company that provides advanced simulation training systems for law enforcement.

Christopher Schurr is the former Grand Rapids police officer on trial for second-degree murder in Lyoya’s death. Schurr testified that he feared for his life during the altercation. If Schurr didn’t shoot Lyoya then “he wouldn’t be here today,” he testified.

David Blake is an expert in police practices and human factors in officer-involved shootings. He testified on how a police officer’s auditory response can be impacted and said it was possible for Schurr to experience auditory exclusion during the scuffle and didn’t hear the second probe deploy from his Taser.

Lewis “Von” Kliem is the director of community relations for Force Science Institute, which provides research and training to help police officers. He analyzes officer-involved shootings. Kliem testified it was reasonable for Schurr to believe that Lyoya was trying to take Schurr’s Taser and use it against him.
