WARREN — Two violent offenders from Trumbull County will remain in prison after their bids at parole were recently denied.

John E. Kopp, 59, who is serving an aggregate 15-years-to-life prison sentence for five counts of rape and other sex charges involving a 14-year-old female victim, was denied release and will have his next parole hearing in March 2032.

Also, John Lysikowski, 65, who is serving a 15-year-to-life prison sentence for an October 1987 conviction of murder, was denied parole with another hearing set for September 2027.

Kopp, who is housed in Richland Correctional Institution, was termed by Trumbull County Assistant Prosecutor Gabe Wildman as a “child pornographer, a pedophile and a child rapist.”

“He preyed on children who trusted him,” Wildman stated in a May 8 letter to the parole board opposing Kopp’s release.

Lysikowski has served 39 years in prison, most recently in Richland Correctional Institution, after being convicted for the June 1987 stabbing death of Warren resident Randy J. Nicholson in Weathersfield.

Lysikowski served very little time in a Florida prison after his arrest in the 1985 stabbing death of a 26-year-old Orange Park, Fla., man whom he argued with in the parking lot of an apartment complex. He was taken into custody by Clay County deputies immediately after the episode. Authorities said a Buck knife was the weapon used in the crime.

After a quick release and a move to the Mahoning Valley, Lysikowski was indicted in a similar murder in Weathersfield after being arrested at the scene with a knife. He was charged with killing Nicholson, 26, of Delaware Street SW, Warren, after the two argued at an address on Clearfield Avenue.

Weathersfield police said when they arrived, they found Nicholson lying on the ground next to a car with a stab wound to his left side.

In his letter to the parole board opposing Lysikowski’s release, Trumbull County Prosecutor Dennis Watkins wrote that his long criminal history of violence and horrible behavioral record in prison qualifies him for a longer stay in prison.

“This non-stop (behavior)… clearly qualifies him as one of the most incorrigible offenders that this office has seen,” Watkins stated, noting that Lysikowski has recently been written up for 18 new rules violations.

He had 99 recorded infractions between 2006 and 2024, ranging from drug abuse and theft to threats against prison staff, according to Watkins’ office.
