A driver has been charged with manslaughter and homicide for the hit-and-run death of a Brooklyn pedestrian.

Police say Alberto Serrano, 31, was struck down by Javier Hernandez on 51st Street at Third Avenue, a few blocks from Serrano’s home in Sunset Park, at around 7 p.m. Monday. Serrano, a husband and father of two young daughters, suffered severe head trauma and died at Lutheran Hospital, according to reports.

Hernandez was charged with second degree manslaughter, criminally negligent homicide, leaving the scene, reckless driving, failure to obey a traffic control signal, and speeding, according to the office of Brooklyn District Attorney Charles Hynes.

It is not often that charges are brought against a sober driver for killing a New York City pedestrian or cyclist, even when the motorist flees the scene. On the rare occasion that such cases are pursued, thanks to rickety state laws and courts that tend to coddle killers who commit their crimes behind the wheel, justice is far from assured. We will follow the case against Javier Hernandez as it develops.
