After two years of legal proceedings, a Queens jury delivered a mixed verdict Wednesday in the trial of the man accused of killing NYPD Detective Jonathan Diller. Guy Rivera was found guilty of aggravated manslaughter and attempted murder but was acquitted of the most serious charge: first-degree murder.
The decision came after a tense deliberation process that nearly stalled. When the jury first announced they had reached a verdict, the court clerk polled them individually to confirm unanimity. Juror No. 5 dissented, disagreeing with the group’s decision on the murder charge. Judge Michael Aloise instructed the panel to return to the jury room, reminding them that there was no time limit but that their verdict must be unanimous.
Following further deliberation, the jury returned with a final decision. Rivera was convicted of aggravated manslaughter in the first degree and attempted murder in the first degree for firing at Sergeant Sasha Rosen, who responded to the scene alongside Diller. He was also found guilty on two counts of criminal possession of a weapon in the second degree.
A Traffic Stop Turned Fatal
The charges stem from an encounter in March 2024 in Far Rockaway, Queens. Authorities stated that Detective Diller and Sergeant Rosen stopped a vehicle that was illegally parked outside a cell phone store. Prosecutors alleged that Rivera shot and killed Diller after being ordered to exit the vehicle.
According to testimony, Rivera then pointed his gun at Sergeant Rosen’s chest and pulled the trigger, but the weapon jammed. Diller managed to wrestle the gun from Rivera’s hand before collapsing from his injuries. Rivera was also shot twice during the confrontation.
The Human Cost
Detective Diller was scheduled to be off duty on the day of the killing. He was at a park with his wife and young son when he was called in to respond to the incident. His widow, Stephanie Diller, attended the trial proceedings, witnessing the conclusion of the case that has dominated her family’s life since March 2024.
Queens District Attorney Melinda Katz issued a statement following the verdict, emphasizing the personal loss behind the legal outcome. “The last words Detective Jonathan Diller told his wife were ‘I love you,'” Katz said. “Detective Diller was a father, a husband and a son. He was also a dedicated member of the New York City Police Department who put on a uniform every day to protect our city.”
The DA’s office noted that the crime endangered the life of Sergeant Rosen as well as stealing the life of Detective Diller. “We continue to stand in solidarity with Detective Diller’s loved ones, Sergeant Sasha Rosen and all the brave men and women who protect our city,” the statement added.
