A man was killed overnight in a crash on Route 16 in Alton, just a short distance away from where his mother died in a car accident last week.

Alexander Gardner, 32, died after his pickup truck crashed into a tree at a high rate of speed, state police said Friday afternoon.

The wreck was discovered around 9:30 a.m. by a passing motorist.

Troopers think the crash occurred sometime during the night and are attempting to retrace Gardner’s movements.

Gardner’s mother, Robin Gardner, 63, was killed Nov. 24 when her car collided head-on with another vehicle, about a mile away from where her son died. The driver of the second vehicle was charged with manslaughter.

State police in Bangor are asking anyone who had contact with Alexander Gardner or saw his red Chevrolet pickup during the night to call them at (207) 973-3700.
