Mass. man dies in Chesterfield crash

CHESTERFIELD -- A 52-year-old Massachusetts man died Wednesday night after he was pinned underneath his tractor-trailer that jack-knifed on Route 9.

He was identified by state police as Fritz Etienne, 52 , of Tewksbury, Mass.

According to state police, the crash happened about 9:50 p.m. Etienne was operating a 2000 Peterbilt conversion tractor with an attached Monarch Van Trailer west on Route 9 when the trailer began to slide due to icy roads.

It skidded off the road and into a snow-covered embankment. State police said it appears Etienne tried to get out the driver's side door at some point during the collision.

However, he was pinned underneath the truck and rescue workers from Chesterfield police and fire departments were unable to extricate him. He died at the scene.

The cause of the collision remains under investigation.

Anyone with information about the collision is asked to call Trooper Rich Camacho at 603-358-3333.
