The ex-cop accused of three revenge killings left behind a long manifesto outlining all of his grievances and observations. That manifesto has given investigators some clues, but they still don’t know where is Christopher Dorner. Law enforcement spent four hours searching his mom’s Orange County home. They took out 10 grocery bags filled with evidence. Dorner lost his job with the Los Angeles Police Department in 2008. His manifesto vows revenge for that; and, surprisingly, thousands of people actually support him. It’s hard to believe but there are those out there who sympathize with the man targeting police officers.
