The crazed gunman who shot dead a Long Island dad visiting his son at upstate Marist College was hit with the maximum life sentence on Monday.

Roy Johnson, 35, was sentenced to 58-years-to-life in state prison following his murder conviction last month in the October 2022 shooting of Paul Kutz at a Courtyard by Marriott hotel in Poughkeepsie, Dutchess County prosecutors said.

“Due to the egregious facts of this case, as well as the immeasurable loss and trauma inflicted on the victims, my office recommended the maximum penalty allowable by law,” Dutchess County Chief Assistant District Matthew Weishaupt said in a statement.

“We are extremely pleased that Judge [Edward] McLoughlin sentenced the defendant in accordance with our recommendation,” Weishaupt said.

“Everyone involved in this case deserves a great deal of credit for remaining focused on the task at hand,” he added. “It was truly an outstanding job.”

Kutz, 53, a married father of three, was in town for Family Weekend at the school and was getting coffee in the hotel lobby shortly before 7:30 a.m. on Oct. 2 when Johnson stumbled into the room acting erratically while waving a gun.

Prosecutors said Johnson was yelling and cursing in the lobby of the hotel and tried to get behind the check-in counter before pulling the trigger of the modified Glock handgun, firing as many as 30 rounds.

Kutz, a Long Island accountant, was struck and died moments later.

Johnson was found guilty of murder, criminal possession of a weapon and reckless endangerment on May 12.

He was handed the max sentence on each charge, with the time to run consecutively.

At the time of the shooting, Johnson was already facing murder and robbery charges in a separate case stemming from the August 2022 shooting death of Darren Villani in Poughkeepsie.

He was indicted in that case in March, and the matter is still pending, court records show.

A second suspect in Kutz’s shooting, 26-year-old Devon Taylor, who was with Johnson in the hotel, was charged with criminal possession of a weapon after cops allegedly found guns in his room.
