NEW YORK (CBSNewYork/AP) — A beloved Staten Island celebrity may have gone out to buy marijuana when he was killed at 2 a.m. Sunday morning.

A friend of slain radio and TV personality DJ Megatron, whose real name is Corey McGriff, told investigators Monday the two were chatting on the phone as the deejay went out to buy marijuana when the line went dead, likely because he’d been shot.

Police said McGriff was shot once in the chest. They are investigating whether drugs played a role in his death, but said Monday they do not believe it was a robbery.

Staten Island residents who spoke with CBS 2’s Pablo Guzman said they were very hurt about the entire situation.

“He helped the community. He helped a lot of people as far as rappers, upcoming rappers, DJs,” Leslie Heath, of Stapleton, said.

Joshua Lopez spoke highly of the slain celeb as he showed Guzman an autographed photo.

“Every time he saw me..he always said ‘hi’ to me — with a hug and everything,” Lopez said.

His manager, Justin Kirkland, known as J. Smoove, said friends and family had no idea why anyone might have attacked the deejay known for his upbeat attitude.

Rising to the on-air ranks after starting as an intern, DJ Megatron began his career at New York’s WKRS-FM, better known as Kiss FM, where deejays remembered him on the air and online Sunday.

He also worked at what was then Boston’s Hot 97.7, or WBOT-FM, and at Philadelphia’s The Beat, or WPHI-FM, according to a bio on his MySpace site.

He was a father of three and also devoted time to charitable events on Staten Island, his manager said.
