A Queens man who took part in a phone store robbery that led to the tragic friendly fire death of NYPD detective Brian Simonsen in 2019 was convicted of murder Monday for his role in the fatal heist.

Jagger Freeman, 28, was found guilty of 13 out of 14 counts he faced, including felony murder and robbery, following a trial in Queens Supreme Court that began in early May.

The convicted cop killer broke down in tears and professed his innocence as officers tried to haul him out of the courtroom following the jury’s verdict.

“For murder though? I didn’t do this sh–t,” he yelled.

Though neither pulled the trigger, Freeman and his accomplice Christopher Ransom were each charged with murder in the February 12, 2019 shooting under a state law that allows for the count if a death is caused during the commission of a felony.

Both men initially pleaded not guilty, but Ransom later copped to aggravated manslaughter and other charges and was sentenced to 33 years in prison in November 2021.

Ransom, 30, was seen brandishing what turned out to be a fake pistol inside the T-Mobile store in Richmond Hill while ordering two employees to fork over cash and merchandise from the back room.

When police officers arrived, he pointed the gun at them, causing several cops to unleash a fusillade of 42 bullets that left Simonsen mortally wounded. Another officer, Sgt. Matthew Gorman, was struck in the leg and later recovered.

Ransom was shot eight times in the melee but survived.

Simonsen, a married 19-year veteran of the department, was struck in the chest and died that night.

Freeman, who was acting as a lookout during the caper, stood across the street from the store when the shots rang out.

He was arrested a few days later after investigators determined he and Ransom had planned the robbery together, as well as another they had pulled off not long before.

Freeman’s attorney Ronald Nir said he was shocked by the verdict. 

“I honestly thought, with the way the jurors had been out last week and the questions they were asking, that they were gonna find him not guilty of the murder, not guilty of things related to Gorman and to Simonsen,” Nir said. “But I did think they would find him guilty of other charges, with regard to the robbery.”

Ultimately, the jury only acquitted Freeman of one of the 14 counts, criminal possession of a weapon in the fourth degree.

He faces up to 25 years to life in prison when he’s sentenced June 30.

Queens District Attorney Melinda Katz said she hoped the verdict brings closure to Simonsen’s family. 

“The jury has spoken,” Katz said in the statement. “The defendant’s actions set in motion a terrible chain of events that began with an armed robbery in progress and resulted in the tragic loss of Detective Brian Simonsen as well as Sergeant Matthew Gorman being shot in the leg.”
