A Sebago teen was killed Tuesday afternoon when his car struck a tree.

Isaac Rawson, 17, was driving on Hancock Pond Road in the town of Denmark about 3:45 p.m. when he lost control of the car and struck a tree, according to Stephen McCausland, spokesperson for the Maine Department of Public Safety.

Rawson, who was alone in the vehicle, died at the scene, McCausland said.

McCausland said that speed and inexperience likely caused the crash.
