State police say a man twice tried to kill himself on Interstate 79 in southwestern Pennsylvania before going to work.

The Associated Press is not identifying the 22-year-old Washington, Pa. man because of the nature of the incidents, but police say he first tried to end his life by jumping out of a moving vehicle that was driving him to work in Canonsburg, about 15 miles south of Pittsburgh. That happened about 7:45 a.m. Tuesday.

About a half hour later, police say the man stepped over a guide rail into the path of a tractor-trailer which tried to avoid the man but knocked him out of his shoes.

Troopers from the Washington barracks say the man jumped up, grabbed his shoes, slid down a hillside and walked to work. He was since been flown to a Pittsburgh hospital.
