NEW YORK — Years before Las Vegas Raiders defensive end Malcolm Koonce was born, his father spent time in prison for an armed robbery conviction that prosecutors now say was tainted by a detective’s lies and “highly suggestive” photo identification techniques.

Jeffrey Koonce, now 67, will ask a suburban New York judge on Friday to vacate his conviction for a 1981 robbery at Vernon Stars Rod and Gun Club in Mount Vernon, where three people were struck by shotgun pellets as patrons were looted of cash and jewelry.

Koonce, who spent nearly eight years in prison, has always maintained his innocence. Westchester County District Attorney Mimi Rocah is backing his request after her office uncovered trouble with the case.

Conviction Review Uncovers Questionable Practices

Rocah’s Conviction Review Unit investigated the 1983 conviction and found evidence that Mount Vernon police pressured the lone victim-witness to implicate Koonce, made Koonce’s picture larger than others in a photo array and failed to interview alibi witnesses who corroborated his claim that he was elsewhere.

A Mount Vernon detective later lied about the composition of the photo arrays when he testified at pretrial hearings and Koonce’s trial, and a court subsequently ordered the department to change its unduly suggestive photo identification practices, Rocah said. One of the detectives involved in Koonce’s case later went to prison following a federal corruption sting.

In a statement, Rocah said Koonce’s conviction “was tainted by such questionable investigatory processes and procedures” that her office can no longer stand by it.

Koonce and his lawyer, Karen Newirth, are set to appear Friday before Westchester County Judge James McCarty to request that he vacate Koonce’s robbery and weapons possession convictions and dismiss the underlying indictment.

“Today marks the end of a 41-year injustice, as Mr. Koonce is finally vindicated in court. DA Mimi Rocah and her team should be commended for their commitment to seeing justice done for Mr. Koonce,” Newirth said.

Case Background and Family Impact

Koonce absconded from court during jury deliberations and was found about seven months later, sleeping on his girlfriend’s couch in the Bronx, according to newspaper reports from the time.

He was sentenced to 7½ to 15 years in prison for the robbery and served a shorter, simultaneous sentence for bail jumping. He was released on parole in August 1992. His brother, Paul, a high school sophomore at the time, also was charged in the robbery. He was acquitted.

Malcolm Koonce was born in 1998. The NFL’s Raiders drafted him in 2021. Another son, Dejuan Koonce, is a retired New York State Trooper who was assigned to protective details for Gov. Kathy Hochul and former Gov. Andrew Cuomo.

Police accused Jeffrey and Paul Koonce of being among the three men who held up the Vernon Stars club on June 20, 1981. Patrons were forced to lie face down on the floor and made to hand over about $500 in cash, jewelry and other valuables, police said.

One of the perpetrators had a sawed-off shotgun and fired off at least two rounds, striking a 15-year-old and two other patrons, police said.

Questionable Investigative Tactics Revealed

Rocah’s office found that detectives used dubious tactics to compel a victim to identify Koonce as the shooter. He was the only person to do so. Others told investigators that it was too dark in the club to identify the perpetrators by their faces.

The witness, a high school freshman at the time, picked Koonce out of a photo array that featured Koonce’s enlarged photo and smaller images of men who didn’t look like him.

The witness later told Rocah’s office that he didn’t remember seeing any faces in the dark club and that other patrons immediately covered him after the shooting, obscuring his view.

Detectives then brought Koonce to the hospital where the witness was being treated so he could identify him in person. The witness told a pretrial hearing that he felt pressured to quickly identify Koonce. The trial judge called the tactic “impermissibly suggestive.”

Rocah’s office also found Mount Vernon detectives harmed Koonce by failing to interview all his alibi witnesses. They include a now-retired New York City police detective who said Koonce was with him in the city the night of the robbery.
