EAST PROVIDENCE, R.I. — Authorities say a box truck was apparently crushed between two tractor-trailers on Interstate 195 in Rhode Island, leaving two Massachusetts residents dead.

State police say the crash happened Tuesday when a tractor-trailer and a box truck slowed for traffic in the westbound lanes. A second tractor-trailer hit the rear of the truck, forcing it into the back of the first tractor-trailer.

The operator of the box truck, 40-year-old Steven Magan, of Palmer, Massachusetts, was declared dead at the scene. His passenger, 38-year-old Axel Moran, of Marlboro, Massachusetts, also died.

The driver of the second tractor-trailer was taken to Rhode Island Hospital with injuries not considered life-threatening. The other driver wasn’t hurt.

The crash tied up traffic on the westbound side of the highway for about five hours.
