MADISON — A Hartland man was killed when a pickup truck he was traveling in left Route 201 in Madison and struck a storage building before rolling onto its roof, the Somerset County Sheriff’s Office said Monday.

Steven Young, 42, was partially ejected from the 2000 GMC pickup and was pronounced dead at the scene, Chief Deputy Mike Mitchell said in a news release.

A second man in the pickup, identified as 55-year-old Paul Pronteau of Sand Coulee, Montana, was not hurt but was arrested later in the day when he became combative with investigators who were questioning him about the wreck, Mitchell told the Morning Sentinel on Tuesday.

Pronteau was charged with disorderly conduct and taken to the Somerset County Jail, Mitchell said. He posted bond and later was released.

Pronteau refused to explain aspects of the wreck, such as who was driving at the time, Mitchell said.

The crash occurred around 6:30 p.m. Sunday on Route 201 about a quarter mile south of the intersection with White School House Road.

The pickup was heading north when it left the road. Neither man was wearing a seat belt, he said.

The wreck remains under investigation to determine why the pickup left the road, he said.

Maine State Police conducted a reconstruction of the crash, and among the emergency responders to the scene were Madison fire personnel and the Upper Kennebec Valley Ambulance Service.
