BAY SHORE - A possible motive has been discovered in the murder of a pregnant woman in Bay Shore.

Suffolk police and federal agents are looking into whether MS-13 gang members shot Milagro Canjura for possibly being an informant, Newsday sources say.

Canjura was killed while sitting in her car Saturday night.

Friends say the 31-year-old had just picked up her mail from her former home on Stein Drive when she was murdered.
