WINTHROP — Police are still investigating a car crash that sent six people to the hospital Sunday, including a teenage girl who suffered serious injuries.

The girl, whose name was withheld because she is under 18, was flown by a LifeFlight helicopter to the hospital, Winthrop Police Chief Joseph Young said Monday. The helicopter was initially headed to Central Maine Medical Center in Lewiston, but was diverted to either Maine Medical Center in Portland or a Boston hospital, Young said.

Young did not know the teenager’s condition. He was also unsure where the other five accident victims were taken and what condition they were in.

The girl was a passenger in a Mazda driven by Theresa Rossignol, 48, of St. Agatha. Rossignol and two other passengers in her car, both of whom were described as juveniles, were taken to the hospital, said Winthrop Police Capt. Ryan Frost.

The driver of the Hyundai crossover that hit Rossignol’s car, Sandra Hodgkins, 71, of Lewiston, and a passenger, John Hodgkins, 74, also of Lewiston, were both taken to the hospital, Frost said.

The crash occurred shortly after 2:30 p.m. as Rossignol’s car left Main Street and attempted to crossed the divided lanes on U.S. Route 202 to head east. Hodgkins was driving west.

Young said it appears Rossignol drove through a stop sign and pulled out in front of Hodgkins’ car.

Young declined to say whether blood samples were taken from the drivers, which is standard procedure in Maine in crashes involving serious injury or death. It could take up to a month to complete the investigation, Young said.

The Maine Department of Transportation has altered traffic patterns through the area in recent years, reducing the number of westbound lanes from two to one.

“We’ve had our fair share of bad accidents right at that intersection,” Young said.
