NJ man found dead in car trunk was last seen alive in Brooklyn as brother fumes he has ‘no idea’ what’s going on with investigation

A New Jersey man who was found dead in the trunk of a car this week was last seen alive in Brooklyn, prosecutors said — as his brother claimed Saturday that he isn’t “getting any answers” from officials.

The body of David Koscuik, 57, of Lakewood, was found around 12:15 p.m. inside the trunk of a vehicle parked in the area of Fairway Court in his hometown, according to Ocean County, NJ, prosecutor Bradley D. Billhimer.

The prosecutor did not reveal the make of the vehicle or what led to the grisly discovery.

Koscuik was last seen alive Feb. 8 in Brooklyn, according to the Manchester Township Police Department, which posted a missing person bulletin on its Instagram two weeks ago. The department did not say where in Brooklyn.

Koscuik was last wearing a black Pittsburgh Steelers sweatshirt and driving a gray 2017 Chevrolet Malibu with Jersey plates, the alert said.

“I have no idea what’s going on. I haven’t been getting any answers [from authorities],” his older brother Anthony Koscuik, 62, fumed to The Post Saturday morning.

“I’m very pissed off. They just told me he was gone.”

Koscuik, who flew in from Orlando, Fla., to help make funeral arrangements, said he last spoke with his brother on Feb. 2.

“I asked him what was going on and he said, ‘I’m just tired.’ That didn’t sound right.”

Anthony Koscuik said his family grew up in Edison, NJ, and his younger brother was a chemical operator who had been living in Lakewood with their mother, who died in September.

He also said David Koscuik had a drug problem, but was in rehab.

Anthony Koscuik said he couldn’t think of any reason why someone would want to hurt his brother.

“He was easygoing. He rolled with the punches. Nothing ever bothered him,” he said. “Maybe his heart gave out and then scumbags threw him in the trunk,” he added.

The investigation into his death “remains active and ongoing; there is no known danger to the public, and additional information will be released when it becomes available,” Ocean County prosecutor Billhimer said.

The NYPD referred The Post to NJ authorities.

The Ocean County prosecutor’s office did not respond to questions from The Post about the matter of Koscuik’s death or if foul play was even involved.
