A Monroe County grand jury has voted to indict the man accused of killing RPD officer Tony Mazurkiewicz.

Kelvin Vickers, 21 of Massachusetts, was supposed to appear in Rochester City Court on Wednesday morning but that hearing was waived. The grand jury indicted Vickers on at least one of the charges against him. We won't know the charges until the grand jury rises which may be after the funeral for the fallen RPD officer.

Vickers is charged with the second-degree murder of Officer Mazurkiewicz. He is being held in Monroe County jail without bail and he first appeared in court on Saturday.

Two RPD officers, Tony Mazurkiewicz and Sino Seng, were shot in the line of duty during an ambush near Bauman Street on Thursday night. Officer Mazurkiewicz has died and Officer Seng is recovering from his injuries.

A 15-year-old girl was also shot during the ambush. A stray bullet went through a wall in her house, hitting her as she was sitting in her living room. News10NBC spoke with the girl, Tamaia Walker, who said she is recovering from the gunshot wound.

RPD said that a suspect, later identified as Vickers, fired 17 shots as he hid behind shrubs from about 10-15 feet away from the two officers, who were in an unmarked police car. The RPD officers were in plain clothes and part of an intelligence unit investigating a recent murder.

Mazurkiewicz, who was in the driver's seat, was shot in the torso. Seng was shot in the leg and exited the car and returned fire. The suspect was not shot and ran away. RPD Chief David Smith said that over 13 police agencies responded to the scene of the shooting.

Mazurkiewicz was taken to Strong Memorial Hospital, where he died at around 11:30 p.m., three hours after the ambush. Seng was taken to Rochester General Hospital and is now at home recovering from at least one gunshot wound to the lower body.

Mazurkiewicz, 54, was a 29-year veteran of the RPD and a father. A vigil at the Public Safety Building honored his service. Fairport, the hometown of Mazurkeiwicz honored his memory by tying blue ribbons around trees along Main Street. Rochester General Hospital and Unity Hospital also displayed blue color to honor Mazurkeiwicz. The last RPD officer killed was Daryl Pierson, a father of two, back in 2014.

Police said they found Vickers shortly after the ambush hiding in the second-floor crawl space of an abandoned house and took him into custody. Police said that Vickers had a loaded 9mm handgun on him. Preliminary firearms testing suggests that it was the gun used in the shooting.

Vickers was charged with murder, attempted murder, assault, and two counts of criminal possession of a weapon all in the second degree. He was arraigned on Saturday morning in Rochester City Court. His last known address is in Brockton, a suburb north of Boston, which is 400 miles from Rochester.

Vickers' attorney entered a not guilty plea for him. A criminal complaint was filed after the plea. Vickers is due back in court for a preliminary hearing on Wednesday, July 27, and he will remain in jail until then. The grand jury will have the final say in what Vickers will be charged with and his murder charge could be upgraded to first degree.

Vickers has had a long history of criminal convictions. He was released from a Massachusetts maximum security prison on May 24 after serving a three-year sentence for a gun possession crime. He was not on parole or supervision after he was released.

Police said Vickers was 12 years old when he faced charges of assault and battery on an officer. Before his 18th birthday, he would be charged with burglary-related offenses, strangulation with a deadly weapon, assault with a deadly weapon, and two separate possession of firearms offenses. When he was 18 he was convicted of possessing an unlicensed firearm.

News10NBC's Berkeley Brean asked Mayor Malik Evans what the suspect from Massachusetts was doing in Rochester. Evans said it's unknown, but it will likely be the focus of the investigation into the murder.

"We will not tolerate people coming from out of state, in state, trying to create havoc in our community," Evans said.
