Oregon Man Killed in Colo. on Nationwide Walk

An Oregon man who lost his gay son to suicide and was walking across the country to raise awareness about bullying is dead after being hit by a truck in eastern Colorado.

The Colorado State Patrol says 48-year-old Joseph Bell of La Grande, Ore., died Wednesday after being struck along a two-lane highway in a rural area 20 miles northwest of Kit Carson. Investigators believe the driver fell asleep.

Bell's 15-year-old son, Jadin, died in February after hanging himself in a schoolyard. He had reported being bullied but he didn't leave a suicide note.

Bell began his walk in April and planned to finish in New York City.

The truck driver, 49-year-old Kenneth Raven, of Bryan, Texas, has been charged with careless driving resulting in death, a misdemeanor.
