A 19-year-old who fled the scene of an accident died Sunday when he crashed into a tree on Route 35 in Naples, according to the Cumberland County Sheriff’s Office.

Ethan Gardner of Otisfield reportedly rear-ended a truck driven by Evert Kinser, 59, of Naples in the area of Routes 302 and 35 in Naples about 1:30 p.m. Witnesses told deputies Gardner left the scene and drove north on Route 35 toward Harrison.

Police said Gardner drove onto the shoulder on the right side of the road, then went across the road and struck a tree. Gardner died in the accident.

Speed appears to be a factor in the crash, which is still under investigation, according to the sheriff’s office.
