The newborn boy who initially survived the hit-and-run accident in Brooklyn that killed both of his Orthodox Jewish parents has died as police close in on the driver that caused the deadly crash.

The 1-day-old boy was delivered by emergency C-section early Sunday morning shortly after his parents, Raizel and Nachman Glauber, died in the crash in Williamsburg. He died early Monday morning, a leader of Brooklyn’s Orthodox Jewish community told the New York media. The boy was expected to be named after his father.

"The only thing I can say is, unfortunately, this little 3-pound-boy would have been at least an umbilical cord for the family to remember the couple. And even that was torn away for them,” Isaac Abraham, the community leader, told the New York Post.

The death of the newborn and his parents has galvanized the Orthodox community to demand justice. The hit-and-run driver is still at large after fleeing the scene on foot.

"The best thing for this coward is to charge him with triple homicide -- and we are going to demand that,” Abraham said.

Police know the name of the driver who caused the accident and were showing the picture of the driver to potential witnesses, sources told the Post.

A driver in a BMW, who did not own the car, was speeding around 12:30 a.m. Sunday when it T-boned into a cab the Glaubers were riding while the taxi was near a stop sign, the New York Post reported. The young Orthodox Jewish couple was heading to a Brooklyn hospital because Raizel, who was seven months pregnant, was experiencing labor pains.

Raizel Glauber, 21, was ejected from the cab and her body wound up underneath a parked tractor trailer, according to the New York Daily News.

The taxi driver was treated and released from Bellevue Hospital.

“I don’t remember anything,” Pedro Nunez, 32, said to the Daily News. Police “told me it was a hit-and-run. There’s an investigation.”

Large numbers of mourners paid their respects to the Glaubers, both 21, at a Williamsburg synagogue for their funeral.

"It’s a great tragedy for the community,” said Rabbi Zalman Leib Teitelbaum of the Khal Yitav Lev synagogue, the Daily News reported. “We have to hold on together and see what we can do to make things better. This is a very, very big tragedy.”

Raizel Glauber’s brother, Nuchem Yoel Silberstein, called her “the crown of the family.

“We were sitting together last night and today she’s gone,” he told mourners, according to the Daily News.

Silberstein also said his brother-in-law was a model husband.

“We can all learn from him how to treat a wife,” he said. “The way he treated her was special.”

Police arrested a woman who co-signed the lease for the BMW; she was charged with insurance fraud, the Post reported.

Takia Walker, 29, allegedly let a third party drive the car despite the third party not being on the insurance.
