WARREN – A Nova Scotia husband and wife involved in a head-on collision with a tow truck Thursday on Route 1 were still hospitalized Friday at different facilities.

The couple’s three daughters and the driver of the tow truck were all treated and released Thursday from Penobscot Bay Medical Center in Rockport.

Sharon Moore, 42, of Shad Bay, Nova Scotia, was taken by ambulance to Pen Bay from the accident scene at the intersection of Routes 1 and 97, but then was transferred by LifeFlight helicopter to Eastern Maine Medical Center in Bangor. She was in serious condition Friday, according to a hospital official in Bangor.

On Friday, Moore’s husband, Carson Moore, 43, was in the intensive care unit at Pen Bay in stable but serious condition, a spokeswoman said.

The Moores’ daughters, Kristy, 9, Tara, 10, and Chantal, 11, were all treated and released, the spokeswoman said. Relatives from Nova Scotia traveled to Maine to take care of the children.

George Knight Jr., 53, of Rockland, who was driving the Mid-Knight Auto Body tow truck with a vehicle on the flatbed and another in tow, also was treated and released, she said.

Knox County Sheriff’s Chief Deputy Todd Butler said Friday that there were no charges stemming from the accident.

Deputy Steven Burns, who investigated the crash, said Thursday that it appeared the Nova Scotia family, who were vacationing in Maine, were unfamiliar with the road. The van failed to stop at a stop sign when it approached Route 1 from Route 97 and was hit nearly head-on by the tow truck, Burns said.
