FRANKLIN TOWNSHIP — Three members of the same family died in a crash with a propane tanker truck on Sunday afternoon, capping off a deadly weekend on New Jersey roadways in which at least nine people died.

Franklin Township police spokesman Lt. Matthew DeCesari told NJ.com the car became wedged under the tanker after driver Mariela Cardoso-Baez, 19, of Bridgeton hit the truck at the intersection of West Boulevard and Lake Road in Franklin Township (Gloucester County) around 3:20 p.m.

The driver's father, Jose Cardoso, 44, and her mother, 45-year-old Adriana Baez Mellado, died at the scene, DeCesari told NJ.com, while an 11-year-old boy survived but required emergency surgery.

DeCesari told NJ.com that extraction efforts were hampered by electrical wires that fell on top of both vehicles.
