Man convicted in 2024 killing of NYPD officer sentenced to 115 years to life in prison
NEW YORK (AP) — A man convicted in the 2024 shooting death of a New York City police officer during a traffic stop will spend the rest of his life behind bars after a judge sentenced him Monday to 115 years to life in prison.
During an emotional hearing in a Queens courtroom packed by uniformed police officers and Officer Jonathan Diller’s family, the judge said Guy Rivera “most certainly will” die in a prison cell.
“Your sentence to me was determined the second you pulled that trigger,” Judge Michael Aloise told Rivera. “It took me five minutes to calculate the numbers. It’s going to take you a lifetime to calculate the damage you caused.”
A jury found Rivera guilty earlier this month of aggravated manslaughter and other charges in Diller's killing, but acquitted the 36-year-old Queens resident of murder.
The shooting happened on March 25, 2024, when Diller and other officers were on patrol in the Far Rockaway section of Queens. Authorities say one of the officers spotted a suspicious object bulging from Rivera’s hoodie as he and another man walked to a parked car and got in.
Police say the officers were questioning the driver when Rivera, who was in the passenger’s seat, suddenly pulled out a gun and shot Diller. The bullet struck the officer below his bulletproof vest, mortally wounding him. Another officer then shot and wounded Rivera.
At the time, Diller was the first NYPD officer to be killed in the line of duty in two years. The 31-year-old’s wake and funeral in his hometown on Long Island drew thousands of people, including President Donald Trump, and the case briefly became a focal point during his 2024 campaign to reclaim the White House on a message of “law and order.”
The Republican president hailed Diller an “unbelievably wonderful person and a great officer” in a March 2025 speech to a joint session of Congress.
Prosecutors had argued that Rivera was deserving of life behind bars because he was a “persistent felon” with prior criminal convictions who had made a “calculated, deliberate and evil choice” to inflict violence.
“This was not an accident,” Assistant District Attorney Kenneth Zawistowski said. “We ask that you honor Jonathan’s life. We ask that you honor his sacrifice."
Rivera's lawyer, Jamal Johnson, argued, as he did during the three-week trial, that Rivera was “not a murderer” because he did not intend to kill Diller.
He maintained the gun accidentally discharged as officers pulled the firearm from Rivera’s pocket. He pleaded with the judge not to issue a “sensational” sentence and complained that Rivera did not receive a fair trial.
Johnson, in a statement after the court hearing, said he intended to appeal his client's conviction.
“The fact that the court stated it had already made up its mind about sentencing well before the trial was conducted reveals the bias and uphill battle the defense faced throughout this case,” he said.
The second suspect, Lindy Jones, is due back in court Tuesday as he awaits trial on weapons charges.
On Monday, Rivera declined to address the court but members of Diller's family delivered tearful remarks.
Stephanie Diller, the officer's wife, said she and the couple's young son had been given a life sentence without their husband and father, so Rivera should also be given one.
“You took my husband and the life we were building,” she said speaking directly to Rivera through tears. “In a single moment, everything that was my life was gone.”
Fran Diller, the officer's mother, said she is haunted by her son's death every day.
“He had a future so incredibly bright,” she said. “My world has been completely shattered. Everything feels empty without him. All I feel is unbearable ache."
Patrick Hendry, president of the police officers’ union, said after the hearing that the manslaughter verdict “did not send the right message” to police officers but that the sentence had.
“He should never ever walk the streets again, and he won't,” Hendry said of Rivera.
