The hit-and-run driver wanted for the death of a couple killed in a Williamsburg car crash — as well as the death of their premature baby — is a convicted killer who was nabbed for drunken driving during a road rage incident just two weeks ago, sources said.

Julio Acevedo, 44, of Brooklyn, was allegedly behind the wheel of the BMW that fatally plowed into the cab carrying Raizy and Nachman Glauber, both 21, early Sunday as they rushed to a hospital for delivery pains, police sources said.

Acevedo had been arrested for drunken driving and released without bail just two weeks earlier, after he got into a road rage incident with a taxi driver at 3:15 am. Feb. 17 in Brooklyn, according to sources and court documents.

The taxi driver called 911 and Acevedo was arrested with a blood alcohol level of .13, far above the legal level, according to sources and court documents. He told police he had had two beers at a baby shower at Sugar Hill Club, court documents show.

In that incident, Acevedo was driving a 1997 BMW 501 with Pennsylvania plates near 411 Lafayette Ave. when cops stopped him for driving erratically, according to the criminal complaint.

He was arraigned the following day and released without bail, court records show. It was not immediately clear whether his license was revoked following the arrest.

But he was allegedly back behind the wheel Sunday, when he plowed a borrowed BMW into a Toyota Camry livery cab headed northbound on Kent Avenue, the NYPD said. He fled the scene on foot, witnesses said.

“I saw the driver through the window. He was trying to get the key out. I told him, ‘Get the hell out of the vehicle. It could explode.’ I told him to sit on the curb,” said a witness, who identified himself only as Asher, 31, who said he saw Acevedo behind the wheel after Sunday’s crash.

Asher said Acevedo was limping and looked shaken up. He briefly sat down on the curb but disappeared when a crowd came, Asher said.
