Gov. Chris Christie is among the mourners scheduled to attend Friday's funeral in Jersey City for Officer Melvin Santiago. The 23-year-old rookie was killed Sunday in what authorities have called an ambush. His assailant was killed during a subsequent shootout.
The city on Thursday promoted Santiago to the rank of detective and posthumously awarded him the department's medal of honor.
Meanwhile, the town of Waldwick also is mourning a police officer.
Patrolman Christopher Goodell was killed early Thursday when his unmarked car was struck by a tractor-trailer.
The truck driver has been charged with vehicular homicide.
