Slain NYPD Officer Jonathan Diller’s wife told jurors on Thursday that their last conversation was about making up for lost time.
Diller, who was shot to death by an ex-con on a Queens street nearly two years ago, was supposed to have the day off, and had started it by sharing a cup of coffee with Stephanie Diller before being called in for a shift at the last minute.

The husband and father packed his lunch and got ready to go to work.
“He said, ‘I love you,’” the widow recalled. “I said, ‘I love you, too. Be safe always.’”
“And he kissed my hand,” she said. “And that was the last time I saw him.”
But she would talk with him again. Later in the day, Jonathan called her to let her know he was skipping his meal break.
”So we can have dinner together,” he told her.
“Jonathan said, ‘I love you. See you soon,’” she said.

A short time later, a neighbor called to see if Stephanie had heard from her husband. The neighbor had heard that a cop from Queens’ 101st Precinct had been shot, and she feared the worst.
“And I said, ‘Well, I just talked to him,” the wife recalled. “‘It’s not him. I’m making dinner.’”
But she started texting Diller, and he wasn’t answering, and when she checked his phone’s location, he was in the hospital.

“So I called my brother and my dad and said, ‘Can you come over, because I think something’s wrong and I’m starting to spiral,’” she said. “I opened the door to get ready for them and my phone started buzzing.”
It was her husband’s former NYPD partner.
“And in that moment, I knew it must be John,” she said. “‘Is it him? Is it John?’ I heard him crying as he said, ‘It is.’”
“How bad is it?” she recalled asking him.
“It’s bad,” the former partner said. “They’re gonna come get you.”
As she spoke before the court, Stephanie Diller touched on her life with her husband, the years they dated and the 3-year-old son they shared.

Stephanie, an assistant nurse manager at Good Samaritan Hospital, said she went into nurse mode at the hospital, where doctors tried desperately to save Diller’s life.
“I just started panic-nursing, and I was asking them, where was he shot, did he have a pulse, did he have consciousness, did he get blood?” she said.
The hospital staff told her to take a deep breath and sit down.
Then the trauma surgeon who worked on Diller, Robert Laskowski, came out with an update.
“I looked up and I said, ‘I’m John’s wife,’ and I could see it in his eyes what he was gonna tell me,” she said.

“Did he die?” she asked him. “Is he dead?”
“And he said to me, ‘Yes he’s dead. I’m sorry.’”
And seven minutes later, the most powerful testimony in the murder trial of accused cop killer Guy Rivera, 35, was over.
“She showed unbelievable strength and courage from that day and every day after that, including today, getting up on that stand,” said Police Benevolent Association President Patrick Hendry. “In an instant, her life was turned upside down. She lost her husband. Ryan, lost his father. She had to pick up the pieces.”
Rivera, who had more than 20 prior arrests before the shooting, faces life in prison for the single-gunshot death of Dillard, 31, who had only been on the force for three years.

On March 25, 2024, while patrolling a street in Far Rockaway, Diller and his partner, Sgt. Sasha Rosen, crossed paths with a man in a hoodie with an L-shaped object tucked in his pocket, authorities said.
They followed him to a car, and asked him several times to roll down his window, cops said. When the door finally opened, Rivera, seated on the passenger side, slowly removed his seatbelt before quickly reaching for his gun and shooting Diller, prosecutors said. The bullet lodged in his hip, below his bullet-proof vest, striking an artery and causing massive internal bleeding.
Diller died a short time later at Jamaica Hospital.
Another officer returned fire, hitting Rivera twice.
Cops said Rivera’s gun jammed after he fired a single, fatal shot, and Rosen escaped unharmed.
Lindy Jones, who was in the driver’s seat of the car that was stopped, has been charged with gun possession
