The suspect in a fatal Brooklyn car crash that killed a pregnant woman, her husband and their unborn baby enroute to the hospital has surrendered to police in Pennsylvania.

Julio Acevedo (NYPD and

Julio Acevedo's surrender at a mini-mart in Bethlehem, Pennsylvania went without incident and he will be extradited to New York City.

Acevedo had been in touch with teh NYPD shortly after the accident early Sunday morning that took the lives of Nachman and Raizy Glauber, both 21, and said he would surrender but was fearful of being shot. He told the New York Daily News that he fled the scene because he was worried he'd be killed, and claimed he didn't know the couple had died until he saw it in the news.

Earlier today, NYPD Commissioner Kelly knocked down that claim and said there were no reports of shots fired in the area at the time of the wreck.

The tragedy unfold shortly after midnight Sunday, when Raizy Glauber, who was seven months pregnant, decided to go to the hospital because she wasn't feeling well, her family said. They called a livery cab, a hired car that is arranged via telephone, not hailed off the street like a yellow cab.

The crash with the BMW reduced the cab to a crumpled heap, and Raizy Glauber was thrown from the wreck. The engine ended up in the back seat. The driver of the livery cab was knocked unconscious but was not seriously hurt.

The couple belonged to a close-knit ultra-Orthodox Jewish community in Brooklyn, which is home to the largest community of ultra-Orthodox Jews outside Israel, more than 250,000. They were members of the Satmar Hasidic sect. Raizy Glauber grew up in a prominent rabbinical family. Her husband was studying at a rabbinical college; his family founded a line of clothing for Orthodox Jews.

The child was delivered by cesarean section after his parents were killed. The baby weighed only about 4 pounds when he was delivered, neighbors and friends said. He died of extreme prematurity, the city medical examiner's office said.

The baby was buried Monday near his parents' graves, according to a spokesman for the Hasidic Jewish community. About a thousand community members turned out for the young couple's funeral a day earlier.

Acevedo, 44, was arrested last month on a charge of driving while under the influence, and the case is pending. He was stopped by police after they said he was driving erratically around 3 a.m. Feb. 17. He had a blood-alcohol level of .13, over the limit of .08, police said.

He served about a decade in prison in the 1990s for manslaughter after he was convicted of shooting Kelvin Martin, a Brooklyn criminal whose moniker "50 Cent" was the inspiration for rapper Curtis Jackson's current stage name.

How Acevedo came to possess the BMW is under investigation. The registered owner was arrested Sunday on insurance fraud charges related to the vehicle, but the case was deferred.
