Former LAPD Chief Bill Bratton on "chilling" memento ex-LAPD officer Christopher Dorner sent to network

(CBS News) More than a dozen local, state, and federal authorities have joined the three-state manhunt for Christopher Dorner, the ex-LAPD officer suspected of killing three people in a vendetta against the police force.

Thursday afternoon, the search shifted to the snowy mountains around Big Bear Lake, about 80 miles east of Los Angeles, where police found his burned-out pickup truck and tracks leading away from the vehicle.

Bill Bratton, Los Angeles Police Chief while Dorner served on the force said Friday that the truck was "possibly a diversionary tactic to just draw people up into that area when he's actually heading south."

Bratton said that despite the increasingly complex search, "the LAPD is superbly equipped for" the hunt.

"The Southern California police community is incredibly well networked with each other," Bratton said. "The manhunt that is underway is coordinated, sophisticated, and very complicated."

Bratton does not remember Dorner personally but did pose for a photo with him before he was deployed to serve in the Navy. Referencing the photo, Bratton said "chances are this is when he was being deployed into the military. I bring them up into my office and wish them well ... and give them a good luck charm."

The good luck charm -- a ceremonial coin -- was one of the props Dorner used, along with a lengthy manifesto, to indicate his targets. Dorner mailed CNN a package and the manifesto referencing Bratton. The package included the ceremonial coin, with Bratton's name on it and three bullet holes in it.

"[It's] very chilling when you see that," Bratton said. "It's a custom that you give as a sign of respect, a good luck charm for those who are going overseas. When you see that that a coin that was given in friendship and respect has three bullet holes, it's certainly very chilling."

Turning to the tactical elements of Dorner's rampage, John Miller -- CBS News senior correspondent and former head of the LAPD Major Crimes Division -- said the attacks likely took a "remarkable amount of pre-staging" and added that "somebody who put that much pre-staging planning into a series of events ... it's doubtful that they didn't put the same amount of planning into the end game ... It makes you wonder what his plan is for the end game."

Bratton said he found it "very surprising that now with all this attention he has brought onto himself, he has not started to reach out to the media to exploit it ... it's very interesting that he has stayed quiet."

Miller explained that Dorner "cut off all his cell phones and other connections" on Jan. 31 and Bratton said, "he's aware that anything he uses electronically can be immediately zeroed in on so he's possibly staying quiet because of that understanding.

As they look to bring the manhunt to an end, "the police are certainly on edge," Bratton said, emphasizing that Dorner is "an incredibly dangerous individual."

Miller added, "He has brought this to a certain pinnacle. It seems like he is going to be moving towards however he wants this to wrap up.
