State Police Investigating Fatal Marion Accident

MARION (CBS) -- The left lane of Route 195 eastbound was closed for about an hour and a half Wednesday morning as State Police investigated a fatal two-car rollover crash.

Troopers responded to the accident around 6:45 a.m. A 2006 Ford Econovan was traveling east near exit 20 in Marion when it lost control, rolling over and killing one man inside.

Three other male victims were transported to Rhode Island Hospital for injuries from the crash. Another person was taken to Tobey Hospital in Wareham, but later transported to a Boston hospital by Med Flight. The victims' names have not yet been released.

The other vehicle involved in the crash was a Ford pickup truck.

The crash is still under investigation, and authorities are not yet sure what caused the van to lose control.
