Murder charges have been filed against Jahmell W. Crockam, 19, in the killing of township police Officer Christopher Matlosz, Ocean County Prosecutor Marlene Lynch Ford said this afternoon.

Crockam, 19, of Lakewood, is known by the street name “”Sav,” which is short for “”Savage,” Ford said. He remains at large.

“”At this point, we need to assume that he is armed and that he will use that lethal weapon,” Ford said.

Crockam was charged with weapons violations on Dec. 29 during an “”incident” that Ford declined to describe. During that incident Crockam was arrested for possession of a rifle and hollow-point bullets. Ford would not comment on whether Matlosz was shot with hollow points. Ford did not comment on Crockam’s possible affiliation with with street gangs. She said his known associates are being questioned and anyone with outstanding warrants is being brought in by police.
