A staunch supporter of the rights of immigrants - and a married father of five - was killed last week when an illegal immigrant from El Salvador facing deportation crashed into his motorcycle in Colorado.
Sean Buchanan, 45, was driving northbound on Highway 83 on August 2 when Colorado State Patrol say a southbound truck operated by Miguel Ramirez Valiente went off the side of the road, then over-corrected into the wrong lane and crashed into Buchanan's bike, killing him.
Valiente, an undocumented immigrant who was slated for deportation eight months earlier, was charged with misdemeanor careless driving with a revoked license in the deadly accident.
In an ironic twist, Buchanan was known among friends a passionate advocate for all immigrants.
