ATLANTIC CITY — A third child has died from injuries sustained in a two-vehicle crash Saturday in Atlantic City.

Four adults also were hurt in the incident, which occurred about 3:15 p.m. Saturday on eastbound Route 40. Authorities were still working Sunday to determine what caused the crash involving a Hummer H2 and a Ford Taurus wagon.

A 13-year-old Pomona boy and a 7-year-old Williamstown girl — both passengers in the wagon — were pronounced dead at the scene. Another passenger, the boy’s 11-year-old brother, died Sunday afternoon at Cooper University Hospital in Camden.

Two other passengers — the boys’ 9-year-old brother and the girl’s 5-year-old sister — remained hospitalized Sunday night.

Both drivers and two other adults in the wagon were treated for undisclosed injuries, none of which were considered life-threatening.

Sgt. Monica McMenamin, spokesperson for the Atlantic City Police Department, said the Taurus wagon was carrying eight passengers when it crashed.
