NY1 has learned that the man police are calling a person of interest in a deadly car accident in Brooklyn will turn himself in. The hit-and-run accident left a young Orthodox Jewish couple and their newborn son dead. A friend of Julio Acevedo, 44, says he is planning to turn himself in, though it is unclear when he will do so. The New York City Police Department says Acevedo was arrested for drunk driving just last month. He also served about 10 years in prison for manslaughter and drug possession in the 1990s. It's unclear whether police think Acevedo was driving the BMW, which was traveling at about 60 miles per hour Sunday morning when it slammed into a livery cab in Williamsburg. Nachman Glauber and his pregnant wife, Raizy, were taking the cab to the hospital because she wasn't feeling well. Both died at the hospital. Their baby boy was delivered prematurely via cesarean section but died Monday morning. "This is a tragedy upon tragedy. There was a lot of hope with this baby, that there would be some kind of memory left from this baby to the family. Unfortunately, that didn't happen. God has his ways," said Gary Schlesinger, a family friend. The livery cab driver survived with minor injuries. The BMW's owner, Takia Walker, 29, is charged with insurance fraud, but police do not think she was directly involved in the crash. A $20,000 reward is being offered in connection with the case. Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
