The California camp ranger carjacked by ex-cop turned fugitive Christopher Dorner last month has filed a lawsuit seeking claim to the entire $1.2 million reward leading to his capture. Rick Heltebrake, who was robbed at gunpoint by Dorner while driving on a Big Bear-area road last month, has filed his suit against the city of Los Angeles claiming that it was his 911 phone call that led to Dorner's cornering.
