The child apparently was on his mother’s lap when the late-model Mercedes sedan struck a utility pole in front of 286 Passaic Street just after 9 p.m., a law enforcement official with direct knowledge of the tragedy said.
The boy "sustained head trauma as a result of the accident and was later pronounced dead at Hackensack University Medical Center," Bergen County Prosecutor Mark Musella said in a brief release Sunday afternoon.
A responder reported seeing a child's car seat in the rear cabin of the car.
"The cause of the accident is under investigation by the Bergen County Prosecutor's Office Fatal Accident Investigation Unit and the Hackensack Police Department," Musella said.
Passaic Street was closed in both directions between Franklin and Haynes places while the Bergen County Sheriff's Bureau of Criminal Identification collected evidence and members of the FAIU began their investigation.
