Dorner's friend: He was fun, intelligent

James Usera describes why Christopher Dorner was well-liked and earned respect from peers when they were college friends at Southern Utah University. He also tells Anderson Cooper why the news about Dorner is so shocking.

"It's indescribable, the sort of emotional roller coaster I've been through the past few days and trying to come to terms with everything that's going on," Usera says about allegations against Dorner and the possibility that the former LAPD officer died in a cabin fire during a standoff with police.

"Chris was a guy who was approachable, had a great sense of humor, fun to be around, intelligent, good conversationalist," says Usera. "The kind of guy most people would want to hang out with and spend time with."

"One of the things about Chris Dorner that I always respected was that he was a person of conviction...I do generally respect that trait, but I think it may be one of the things that brought about his demise in this case," Usera added.
