ROCHESTER, N.Y. — Lynn Mazurkiewicz, the widow of slain Rochester Police Officer Tony Mazurkiewicz, is speaking out after investigators say the man who murdered her husband attacked a corrections officer on video.

The video surfaced on social media showing a man, who appears to be convicted murderer Kelvin Vickers, and two others attacking the guard inside Coxsackie Correctional Facility. Lynn Mazurkiewicz said she’s not surprised by Vickers’ attack on Corrections Officer Corey Clark on Jan. 6.

“There is no question in my mind he had every intention of killing him. I’m not shocked by anything he does, because he’s an animal. He’s cruel, violent, he’s just evil,” she said.

She has been closely following Vickers since his incarceration and claims this is not the first time he has attacked a corrections officer.

“You just don’t get transferred around just because you checked out the wrong library book,” she said.

Lynn Mazurkiewicz fears it is only a matter of time before Vickers kills someone else. She believes he should be placed in solitary confinement for life.

“Because he’s put my family in a type of solitary confinement as well,” she added.

Rochester Police Chief David Smith also shared his reaction. He expressed concern over the safety of both prisoners and guards.

“To think that something like this can happen, this individual is able to get a weapon and allegedly attack an officer is beyond the pale,” he said.

Chief Smith says Vickers has traumatized Lynn’s family and the police department’s family. He took away a valuable member of both families.

“No injury is a small injury. My heart goes out to this C.O. and his family because I know what it’s like,” he said.

Lynn Mazurkiewicz has a message for Gov. Hochul: “These men and women who are working with people like Kelvin Vickers, they are in danger every single day. And this video just shows how much danger.”

The case is currently before the Greene County Grand Jury. Vickers is now at Attica Prison, serving a life sentence without parole.
