Police have identified the two people killed Monday afternoon in a one-vehicle crash on Interstate 95 in Howland.

The driver -- Michael Dentico, 63, of Arundel -- died at the scene.

A passenger -- Jacqueline Gordon , 66, of Ellsworth -- died en route to the hospital.

Neither were wearing seat belts and both were thrown out of the pickup truck. Troopers say Dentico likely fell asleep.

A second passenger -- Tammy Dentico, 43, of Arundel -- had minor injuries.

Witnesses told troopers the 2004 Chevrolet pickup drifted into the median before abruptly veering back across both lanes and into the ditch on the right side of the road.

No one in the truck was wearing a seat belt.
