An 80-year-old woman died from injuries she sustained in a single-vehicle crash on Route 1 in Searsport Thursday afternoon, Sept. 16.

Eve Cassatt of Brooksville succumbed to her injuries at Eastern Maine Medical Center Thursday night, just hours after the accident.

Cassatt’s husband, 81-year-old Robert Cassatt, who was driving, and the two other passengers, William and Grace Gregor of Brooksville, were all taken to Waldo County General Hospital. Eve Cassatt was taken to Bangor by LifeFlight helicopter.

Sgt. Steve Saucier with the Searsport Police Department said Robert Cassatt and the Gregors are expected to recover from their injuries.

The crash tied up Route 1 traffic for about 90 minutes Thursday afternoon.

At the scene, Searsport Police Officer Jessica Danielson said  Robert Cassatt was headed towards Stockton Springs when he veered across the oncoming lane and up onto the lawn of Bayview Manor and struck a tree head-on. Both airbags deployed, Danielson said.

The crash occurred shortly before 3:30 p.m.

Saucier said Friday morning that the accident remained under investigation, but that the Cassatts’ daughter was at the scene and told police that her father has Parkinson’s disease. Saucier did not know if Robert Cassatt’s medical condition was a contributing factor in the accident.

Ambulance services from Searsport, Belfast and Stockton Springs were all called to the scene to assist in transporting accident victims.

Searsport police had assistance with traffic control from the Searsport Fire Department and Maine State Police. Traffic on Route 1 began backing up after the accident occurred, but Danielson said detour signs were put up on both ends of town to help re-route motorists who were approaching the scene.

Belfast police officers assisted with re-routing traffic at the intersection of Route 1 and Route 141, on the east side of the Veterans Memorial Bridge, then onto the Back Searsport Road.

The scene in Searsport was cleared around 5 p.m. Thursday.
