MONTVILLE – One teenage girl was killed and two others critically injured in a two-vehicle crash on Route 220 in Montville on Wednesday.

The crash was the second fatality in the state Wednesday afternoon.

Maine State Police said 19-year-old Cassandra Locke of Knox was killed instantly when the car she was driving slammed into a pickup truck on a curve.

Locke’s two passengers were thrown from the car onto the pavement, police said. Being treated at Eastern Maine Medical Center in Bangor with multiple injuries Wednesday night were Danielle Harriman, 16, and Cassie Hall, 15, both of Liberty.

Investigating Trooper Stephen Hills said none of the three teens were wearing seat belts. All three girls were students at Mount View High School in Thorndike. School officials said counselors will be available Thursday and students should call the high school for details.

Trooper Hills said Locke had attempted to pass a second pickup, lost control of her 1992 Saturn, and collided head-on with a pickup driven by John Studley, 63, of Somerville.

Studley and his 66-year-old wife, Grayce, were taken to Waldo General Hospital in Belfast, police said. Montville is west of Belfast in Waldo County.

About 12:15 p.m., 85-year-old Gertrude Chisholm was killed in a wreck on Route 11 in Newfield. State Police Trooper Lauren Reese said Chisholm’s 2000 Ford Focus traveled off the roadway onto a lawn, struck a tree and overturned on its side. The woman was partially ejected and died at the scene, police said.

Newfield is on the New Hampshire border in York County.
