Slain NYPD Detective Jonathan Diller’s widow, mom tear into his killer as judge throws the book at him
The grieving widow of slain NYPD Detective Jonathan Diller tore into his killer in a Queens courtroom Monday — moments before a judge sent him to the slammer for life.
Stephanie Diller delivered an emotional statement denouncing Guy Rivera, 36, for the senseless 2024 shooting death of her husband as dozens of New York’s Finest looked on.
“One day you will stand before God and answer for what you did to Jonathan,” she told her husband’s killer.
“You have given us a life sentence without him.”
Queens Supreme Court Justice Michael Aloise said the hefty prison term was an easy decision — sentencing the cop-killer to 115 years to life in prison.
“Mr. Rivera, it took me five minutes to calculate these numbers,” he said. “It will take you a lifetime to calculate the grief you have caused these people.
“And to the family,” the judge added, “I know the defendant killed your loved one, and nothing can take away that loss, not even the knowledge that the defendant will die in a prison cell, which I promise you he will.”
Diller’s wife, who delivered powerful testimony during Rivera’s trial, also slammed him for leaving her young son without a father.
“There is a silence in our house where there should be his voice. The person who lost the most is our son Ryan,” she said.
The slain cop’s mother, Fran Diller, then took her turn, pleading for the judge to deliver the maximum sentence allowed by law.
“Your honor, I have watched the defendant in court over the last two years. I have never seen any remorse, only concern for himself,” she said.
“He didn’t just take our loved one, he took our whole world,” the grieving woman continued. “My son deserves justice.”
Rivera shot and killed Diller during a scuffle with police in Far Rockaway on March 25, 2024, with the fatal encounter caught on chilling bodycam.
Dozens of NYPD officers packed the courtroom during the thug’s trial, providing support for the fallen cop’s widow, who broke down on April 1 when the jury acquitted Rivera of the top murder charge.
Rivera was instead convicted of manslaughter, of the attempted murder of NYPD Sgt. Sasha Rosen and of illegal weapons charges.
The career criminal faced a sentence of 90 years to life behind bars, but Aloise tacked on another 25 years, as allowed under state law for “persistent predicate felons,” due to his lengthy rap sheet.
Queens District Attorney Melinda Katz said her office made the request, adding in a statement that “today’s sentence of 115 years to life in prison does not erase the tragedy of March 25, 2024, but it ensures that this defendant will never be free again to terrorize the streets of New York City.”
“This defendant ignored repeated lawful commands and used an illegal firearm to kill a dedicated police officer and attempt to murder an NYPD sergeant,” Katz said. “Jonathan Diller represented the very best of law enforcement: courage, commitment and service to community. He 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 void left by his senseless loss at the hands of this defendant is immeasurable.”
Rivera, who was dressed in all black, opted not to address the court during the sentencing hearing — while his lawyer griped that he did not get a fair trial and harped on the murder charge acquittal.
“Under the law, he is not a murderer because he never intended to murder Jonathan Diller,” defense attorney Jamall Johnson told the judge. “Mr. Rivera did not receive a fair trial. The jury did not have all of the evidence.”
Johnson said he would appeal the verdict — but the judge had his own reprimand for the lawyer.
“There was one argument you made to this jury that really hit home,” Aloise said, referring to Johnson’s claims at trial that his client had just made a bad decision.
“I wasn’t mad at you for doing it. I was saddened at the reality of how low we’ve sunk, morally, as a society,” Aloise told the lawyer Monday.
“When you equate a persistent felon walking these streets with a loaded weapon with one bad decision, it’s sad,” he said. “And it’s just the reality of where we are now, and that mindset, I think that is what empowers a guy like this.”
Rivera’s acquittal of first-degree murder — which carried a sentence of life without chance of parole — had outraged Diller’s family and their supporters.
Police Commissioner Jessica Tisch called the jury verdict “a gut punch to all members of the NYPD,” while the department’s union said the hero cop’s family was “devastated.”
“The decision at least gives Jonathan and his family some justice,” Police Benevolent Association President Patrick Hendry had said about the verdict. “But it doesn’t give them full closure. The pain will never go away.”
Hendry slammed Rivera’s lawyer following Monday’s sentencing.
“Let’s make no mistake, despite what the defense said this is a murderer,” the union boss told reporters. “He should never walk the streets again — and he won’t. He won’t because this judge sent a clear message with this lifetime sentence to everyone who dares harm a New York City police officer.”
