NYC serial killer? New York City police release sketch of suspect believed targeting store owners

New York City Police have released a sketch of the man believed to be targeting and killing store owners in Brooklyn.

Investigators are looking for a male in his 20s, around five-foot-nine, with a medium build.

According to Police Commissioner Ray Kelly said Monday that police are trying to identify a tall, balding man with a mustache who was seen on surveillance video wearing an overcoat and carrying a black duffel bag near the scene of the latest shooting. 

All three victims are of Middle Eastern descent and none of their stores had surveillance cameras.

Police also say the gunman shot all three men in the head, pulled their bodies away from the stores' front windows and covered them with clothes or merchandise.

The victims were murdered over the last four months, the latest coming Friday.

N-Y-P-D has a hate-crimes detective working the case.

WABC says the FBI is now involved.
