NYPD Officer's Killer Sentenced to 115 Years in Queens Court

Conviction and Sentencing

Guy Rivera was sentenced Monday to 115 years to life in prison for the 2024 killing of NYPD Detective Jonathan Diller during a traffic stop in the Far Rockaway neighborhood of Queens. Queens Supreme Court Justice Michael Aloise handed down the sentence after designating Rivera a persistent felony offender, running all convictions consecutively. A jury had convicted Rivera earlier this month of aggravated manslaughter, attempted murder of a second officer, and two counts of criminal possession of a weapon. The same jury acquitted him of first-degree murder, a decision that drew immediate backlash from law enforcement.

Aloise was direct in his remarks from the bench. “Your sentence to me was determined the second you pulled that trigger,” he told Rivera. “It’s going to take you a lifetime to calculate the damage you caused.” The judge added that Rivera would “most certainly” die in a prison cell.

What Happened on March 25, 2024

Diller and other members of the NYPD’s Community Response Team approached a vehicle parked illegally at a bus stop near Mott Avenue and Beach 19th Street in Far Rockaway shortly before 6 p.m. Authorities say officers spotted a suspicious object under Rivera’s hoodie as he and another man walked toward the car and got in. While officers were questioning the driver, Rivera, seated in the passenger seat, drew a .380-caliber handgun and fired, striking Diller below his bulletproof vest. Rivera then pointed the weapon at Sergeant Sasha Rosen, but the gun jammed. Diller was rushed to Jamaica Hospital Medical Center, where he died. He was the first NYPD officer killed in the line of duty in two years.

Rivera’s defense argued throughout the three-week trial that the shooting was accidental - that the gun discharged during a struggle with Rosen - and that Rivera did not intend to pull the trigger. That argument held enough weight with jurors to defeat the first-degree murder charge, but not enough to escape the lesser convictions. Rivera declined to address the court at sentencing on the advice of his attorney, who said he planned to appeal.

Families and Colleagues in Court

The sentencing drew a packed courtroom and a large showing of uniformed NYPD officers gathered outside. Diller’s widow, Stephanie Diller, addressed Rivera directly. “Every moment brings me back to that day, my life changed forever,” she said. “The person who lost the most is our son, Ryan. He will grow up without his father.” Diller’s mother told the court she had been given 31 years with her son before he was taken from her. “My world has been completely shattered,” she said.

Diller was posthumously promoted to Detective First Grade. The case became a significant focal point during the 2024 presidential campaign, when then-candidate Donald Trump attended the officer’s wake and referenced the killing repeatedly on the trail. NYPD Commissioner Jessica Tisch said Monday that the sentence meant Rivera would spend the rest of his life in prison, calling it the right result for anyone who kills a New York City police officer.

Legal Posture Going Forward

Rivera’s attorney, Jamal Johnson of the Legal Aid Society, said he would file an appeal, arguing that pre-trial rulings by Aloise had limited the jury’s ability to consider lesser charges and unfairly constrained the defense. A second suspect in the case, Lindy Jones - the driver of the vehicle - has not yet stood trial and remains pending on weapons charges. Rivera received 25 years to life for aggravated manslaughter, 40 years to life for attempted murder of Sergeant Rosen, and 25 years to life on each of the two weapons charges, all running consecutively.
