Christopher Stella raised his off-duty Glock 9 mm pistol to his head and shot himself, according to law-enforcement sources.

It was unclear why Christopher Stella, of Great Kills, took his own life, and law-enforcement sources said it appeared he left no note.
Stella first smashed his own car into two parked vehicles at the King Kullen supermarket in Greenridge Plaza at about 3:30 a.m., cops said.
He then raised his off-duty Glock 9 mm pistol to his head and shot himself, according to law-enforcement sources. "He was a good kid, quiet kid, no problems," said one colleague in the 72nd Precinct in Sunset Park, Brooklyn. Officials also noted that Stella was not under departmental investigation.
