The NYPD has released this photo of the man believed to have been behind the wheel of a BMW that crashed into a livery cab in Williamsburg shortly after midnight on Sunday morning, killing a young married couple and their unborn child. Investigators are on the hunt for one Julio Acevedo, 44, who is suspected of fleeing the scene of the accident on foot, leaving Nathan and Raizy Glauber, both 21, for dead. Raizy was seven months pregnant, and her infant son was briefly saved through cesarean section, but subsequently died this morning.

Police say the BMW was not registered to Acevedo, but rather one Takia Walker, 29, of the Bronx. She was arrested and charged with insurance fraud yesterday; investigators tell the Wall Street Journal she "acquired the car under false pretense and allowed another person who was not insured to drive the 2010 grey BMW sedan." Acevedo was arrested for drunk driving on February 17th and was released without bail. Police sources tell ABC 7 he served ten years in state prison on a 1989 manslaughter conviction.

"We have identified him and are looking to talk to him in connection with these deaths," NYPD spokesman Paul Browne told reporters today. "We believe he was the driver of the BMW and fled the scene." According to a woman who identified herself as Acevedo's mother (while insisting she "didn't raise him"), Acevedo will turn himself in. “I know why you are here," the sobbing woman told the Daily News from behind the closed door of her Brooklyn apartment. "You are here for my son. He doesn't live here. I don't want to talk. I have nothing to say. Tell the family of my condolences."
