In the aftermath of the horrifying accident, friends rushed to the hospital to visit the newborn tenaciously clinging to life, then on to the synagogue for the funeral of his parents. The boy’s birthday would fall on the anniversary of his parents’ death; their burial would occur well before his bris, the circumcision ritual that Jews have honored for thousands of years, and his naming.

Even for a community accustomed to burying its dead quickly, it was a shattering avalanche of events.

The crash happened at Kent Avenue and Wilson Street. The police said the livery cab, a black 2008 Toyota Camry, was traveling west on Wilson Street when it was struck on the driver’s side by the 2010 BMW, which had been going north on Kent.

It was not clear if one or both of the drivers was at fault, the police said; the crash was still under investigation. The driver of the BMW is expected to face an eventual charge of fleeing the scene of the accident.
