Julio Acevedo: Hit-and-run driver wanted in Jewish death crash served eight years in prison for the murder of the original '50 Cent' The man wanted for driving the car that killed a pregnant woman, her husband and their child in Brooklyn has said his 'heart goes out to' the young family. Julio Acevedo, 44, has eluded authorities since fleeing the crash that killed Nachman and Raizy Glauber, both 21, on Sunday. Their son, who was delivered by caesarean section, died on Monday. But on Tuesday he vowed to turn himself in as he spoke out for the first time since the deaths. 'My heart goes out to them,' Acevedo said of the couple as he spoke to the New York Daily News over the phone. 'I didn't know they died until I saw the news.' Killer: Police are looking for Julio Acevedo, 44, in connection with the deaths of an expectant couple in Brooklyn. He previously served time in prison for shooting Kelvin '50 Cent' Martin, right, to death in 1987 Origins: His name inspired rapper 50 Cent, pictured, whose real name is Curtis Jackson He added that he had been fleeing from gunshots when his car smashed into the cab carrying the couple to hospital. He said he is making contact with a lawyer before contacting police. It also emerged on Tuesday that Acevedo served eight years for a first-degree manslaughter charge for the 1987 shooting of his one-time associate Kelvin Martin, who went by the nickname of '50 Cent'. Martin was the inspiration for the moniker assumed by platinum-selling rapper Curtis Jackson. Acevedo has a long criminal record that includes time in Attica prison for Martin's death, two arrests for drug possession and arrests for robbery and reckless endangerment. His record also includes a 1997 robbery in the Bronx. Just two weeks before the deadly crash in Williamsburg, he was stopped by police for driving erratically and his blood alcohol level was far above the legal level at .13. Kelvin Martin lived at a housing project in Fort Greene, Brooklyn and terrorized the streets throughout the 1980s until his death aged 23. He made a living through robberies and allegedly murdered local hustlers. Friends estimate that he sustained 24 bullet wounds and murdered at least 30 people in his life. According to legend, Martin also stole from rap stars, such as LL Cool J. He allegedly robbed a gold chain from the rapper's neck in a parking lot in Brooklyn. He was nicknamed '50 Cent' by his associates, but there are different theories over its origin. It has been claimed the name came from his small stature - he was just 5ft 2 and weighed 120 pounds. Others say it referred to his robbery habit and how he would steal from someone, even if it were just for 50 cents. Another theory is that he once put down 50 cents in a dice game and won $500 back. He was shot by Julio Acevedo on October 20, 1987 on the stairway of his girlfriend's building and died from hemorrhaging four days later. Acevedo was convicted of first-degree manslaughter and sentenced to a minimum of eight years in prison for the death. In an interview with Vanity Fair last month, the rapper 50 Cent said: 'There was actually a guy from the Fort Greene projects [in Brooklyn, New York] who called himself 50 Cent. I used it as a metaphor for change. Musically, I had my own way of doing things. He told police he had drunk just two beers at a baby shower before he was pulled over. A friend of Acevedo's from prison said Acevedo has called him seeking guidance at least four times since the crash, according to the New York Times. 'He has remorse,' the friend said. He wants to turn himself in. Isaac Abraham, a spokesman for the family's Orthodox Jewish community, called Acevedo a 'coward' before his arrest and demanded he be charged for three deaths. The Glaubers had been heading to hospital in a taxi early on Sunday morning after Raizi, who was seven months pregnant, felt an unusual pain. Resting place: The original 50 Cent was given this headstone in Staten Island after a documentary about the rapper revealed he had died penniless and could not afford a proper burial Neighbors and friends said the boy weighed only about 2 pounds. The baby was placed in a tiny coffin and buried early on Monday afternoon in a separate area of the cemetery in Kiryas Joel where his parents were laid to rest Sunday. At the funeral on Sunday Rabbi Zalman Leib Teitelbaum addressed the mourners in Yiddish.
