Suspect in Brooklyn hit-and-run proclaims his innocence

(CNN) -- The suspect in a hit-and-run crash that killed a New York couple and their baby told a court Thursday he is innocent of charges of second-degree manslaughter and criminally negligent homicide, the Kings County District Attorney's office said.

Julio Acevedo, 44, was indicted last week, accused of driving a car that hit a livery cab carrying Nathan and Raizy Glauber, both 21, on March 3. He was also charged with leaving the scene of an incident.

Raizy Glauber was pregnant; she and her husband were going to the hospital because she wasn't feeling well, said her cousin, Sarah Gluck.

The couple's baby boy was delivered by cesarean section from his dead mother's womb but died the next day, police said.

Acevedo, who was arrested several days later in Pennsylvania, could face up to life in prison if convicted.

An investigation found that Acevedo was traveling at almost 70 mph, more than twice the legal speed limit for where the accident happened, at an intersection in Williamsburg, Brooklyn. Acevedo fled on foot after the collision, the district attorney's office said.

The driver of the cab survived. The front of the BMW was smashed but the black Toyota Camry cab was left a mangled wreck. The driver's side was crushed, the front wheel was hanging off, and pieces of metal were bent in every direction.

The deaths brought heartache to the Glaubers' close-knit, ultra-Orthodox Jewish community in Brooklyn.

"A loss like that cannot be replaced by having him arrested or by surrendering or no matter what charges will be brought against him once he finally faces up to the justice system," Isaac Abraham, an Hasidic community leader and neighbor of the couple, said in early March.

The young couple were "preparing for the most joyous moment in life, to become parents, ready to build a castle to the future and build a family," he told CNN affliate WABC.
