Three men were injured, one critically, when the 2001 Jeep Wrangler they were riding in rolled over on Five Islands Road in Georgetown on Wednesday evening.

Sheriff Joel Merry said the driver, James Moran, 50, of Bath, suffered internal injuries and was taken to Maine Medical Center in Portland, where he was listed in critical condition.

A passenger, Richard Heffron, 38, was also taken to Maine Med and was listed in fair condition.

The third occupant, Michael Tibbetts, 60, of Georgetown, was treated for less serious injuries at Mid Coast Hospital in Brunswick, according to Merry.

Merry said Moran got pinned in the Jeep, which has a soft top, when it crashed in the vicinity of 83 Five Islands Road.

The cause of the crash is under investigation by Deputy Brian Carlton, who is being assisted by an accident reconstruction specialist from the Bath Police Department.
