MOUNT LAUREL, N.J. (WXIA) -- Three people from a Stone Mountain family were killed in an accident Thursday on the New Jersey Turnpike in Mount Laurel, authorities said.
Drew Mallett, 51, his 49-year-old wife Jacqueline and their 12-year-old son Drew died in the crash.
Another child, 18-year-old Nicole, survived the accident with what police said were minor injuries and was taken to Cooper University Hospital with non-life threatening injuries. Police said the family's dog also died in the collision.
Our Philadelphia sister station, WCAU, said the wreck happened at about 10 a.m. in the southbound lane at milepost 39.9, when a tractor-trailer hit a silver Toyota Camry from behind and bumped a Ford Edge. Police said that as the tractor-trailer jackknifed, the Camry was crushed and apparently pushed into another tractor-trailer.
The roadway was closed at the scene of the wreck for more than five hours, police said.
Investigators said Drew Sr., Drew Jr. and Jacqueline Mallett were pronounced dead at the scene of the accident.
Police said all the victims were in the Toyota. The cause of the wreck is under investigation.
