NEW YORK (AP) — Authorities were looking for a man with a history of violence and a prior drunken driving arrest suspected of barreling down a street and crashing into a pregnant woman and her husband, killing them and ultimately the child they were expecting.

Police identified the suspected driver as Julio Acevedo, and said he was speeding down the Brooklyn street in a BMW at 60 mph early Sunday when he collided with another car carrying Nachman and Raizy Glauber, both 21. They died Sunday, and their premature son died Monday.

Acevedo, 44, was arrested last month on a charge of driving while under the influence, and the case is pending. He served about a decade in prison in the 1990s for manslaughter. No one answered the door at Acevedo's last known address, in a public housing complex in Brooklyn. Neighbors said his mother lived in the same building, but she did not answer her door.
