Yeah. He was born with facial deformities and mental disability. The other campers at Camp Crystal Lake picked on him and he fell into the lake and supposedly drowned. His mother went crazy and started killing everyone at the camp except for one counselor who decapitated her. Jason was there when his mother was killed. He then went on his own killer spree. His first victim being the woman who decapitated his mother. He now keeps his mother's severed head as a trophy.
