ROCHESTER, N.Y. (WROC) — Closing arguments in the trial of a man accused of shooting and killing a Rochester police officer began Tuesday morning as jurors and attorneys were escorted into the courtroom.

The defense began their argument by opening with “shots fired,” which were the words used by the prosecution’s opening statement. They then asked the jurors to consider the area where Officer Mazurkiewicz was shot and killed as a “war zone.”

The defense continues to instruct the jury to consider Vickers guilty “beyond a reasonable doubt.”

During the prosecution’s opening statement, Monroe County DA Sandra Doorley began by reminding the jurors that this was Vickers’ trial, not a trial on gang war. She is asking the jury to consider what Vickers did between July 19 through July 21.

The prosecution says that they are confident that the evidence presented during the trial will prove beyond a reasonable doubt that Vickers is guilty, noting the video evidence. Doorley added that it was proven that Vickers was responsible for the arson of a Dodge Caliber.

On the night of July 21, 2022, Officer Mazurkiewicz was inside an unmarked police car with his partner Officer Sino Seng when a suspect went up to the car and fired shots, fatally striking Officer Mazurkiewicz. Officer Seng and a 15-year-old girl in a nearby house were also hit.

22-year-old Kelvin Vickers of Boston was identified as the suspect as police said they found him hiding inside a vacant house near the scene of the shooting.

Jury selection in Vickers’ trial began last month as the jury heard testimonies from police officers — including Officer Seng — and watched surveillance footage from the day of the shooting.

After the closing arguments are finished, the jury must then decide whether Vickers killed Officer Mazurkiewicz and if the shooter knew that there were officers inside the unmarked van on the night of the shooting.

Monroe County Court Judge Julie Hahn will instruct the jury Wednesday morning

Deliberations in Vickers’ trial is scheduled to begin on Wednesday at 9:30 a.m. The judge is expected to deliver instructions to the jury on that morning.
