There's nothing to indicate Dorner is headed our way, but police chief Jerry Dyer shared how manhunts are coordinated here.
Sheriff Margaret Mims, has been in southern California all week watching the situation unfold.
Hundreds of law enforcement officers are on an unprecedented manhunt for former LA police officer Christopher Dorner, who, police fear, could be hunting them.
Sheriff John McMahon, San Bernardino County: "It's extremely dangerous. I explained to them to be careful."
The bad weather is burdening a massive search of the Big Bear mountain area, east of Los Angeles.
So far, the search has turned up empty.
Clint Van Sandt, Former FBI Profiler: "As long as he's out there, he's a threat not only to law enforcement, but to the general public, too."
According to a Facebook manifesto police attribute to him, Dorner's anger has been simmering since he joined the force.
The manifesto accuses the LAPD of betraying and destroying lives, including his, and says the killing will stop only when the truth comes out.
The truth for police?
The daughter of a retired police captain, and her fiance, were shot and killed. And three officers have also been shot, with one dead. And the suspect is still on the loose.
Police chief Jerry Dyer shared his thoughts on the manifesto.
"He thrives on creating panic. And so we can't become fearful and we can't panic."
Chief Dyer says Fresno has been involved in manhunts before, but nothing like this.
"The individual that shot Brian Nieto, we had an extensive manhunt there involving state and federal authorities as we as is, centralized command and control."
There's nothing to indicate that Christopher Dorner would be heading to the central valley, but the chief says that "centralized command" is key to coordinating a local manhunt.
He says his officers are prepared.
"There's always a potential for copycats and we always have to be prepared for that."
Sheriff Margaret Mims was been in southern California this week for the state sheriff's meeting, where extra security was provided.
Sheriff Mims agrees with the centralized command approach.
She's also the mutual aid coordinator for 7 counties.
"We would all pull together, like we always do whenever we have something serious, devastating and large scale. We have a lot of resources at our disposal."
While this is a southern California coordinated search, Chief Dyer says it's important for residents to know what Christopher Dorner looks like, and to report any sightings right away.
Meanwhile, police involved in the manhunt are facing harsh criticism after firing on two cars they feared might be Dorner's.
A 71-year-old woman delivering newspapers was shot multiple times in her back, and her daughter was also injured.
