NEW YORK — A friend of slain radio and TV personality DJ Megatron 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.

The friend was on the phone with the 32-year-old deejay, whose real name is Corey McGriff, at around 2 a.m. Sunday when the line suddenly went dead, police said. The deejay, also known as Mega and or Mega McGriff, was later found shot once in the chest. Police said he had been walking to a store near his home on New York’s Staten Island.

Police were looking at whether drugs may have played a role in his death. He had a few previous minor arrests for possession of marijuana, but no serious crimes. Police said Monday they do not believe it was a robbery. No arrests have been made.
