UPDATE 4:26 p.m. Police are set to pull back officers from Bear Mountain overnight, though they expect their search of cabins to be completed after dark.
"They have to rest," San Bernardino County Sheriff's Department spokeswoman Cindy Bachman said. "They probably would stay there all night and search through the forest, if they could."
However, she added that she didn't think that overnight search would be very productive. Dorner remains at large as the search continues.
"Obviously he's armed. He's shot several people over the past week," Bachman said.
The tracks that were investigated also included ski tracks associated with them, but they didn't lead to Dorner.
Overnight, there will still be 12 additional two-man patrols in Big Bear Lake, along with the regular patrol.
Bachman said there was no indication that Dorner had an accomplice.
Saturday, they also have to give up their command post, which belongs to a local golf course, and move to the Big Bear sheriff's station.
Bachman said that people can come up to the mountain, though driving remains dangerous due to the weather.
The next news conference is scheduled for noon Saturday, unless news breaks first.

UPDATE 12:38 p.m. LAPD back on tactical alert
LAPD went on "tac" or tactical alert around 11:45 a.m., according to Rudy Lopez from LAPD Media Relations. They'd been on tactical alert before, but it was lifted before 7:30 a.m. this morning — now it's back on.
It's due to a high call load for service, according to Lopez. Some of it is related to the Dorner search, including reported potential sightings.
Lopez said that LAPD officers don't want to think of Dorner as "one of [their] own."
There's no ETA for when the tac alert will be lifted once again.

UPDATE 12:28 p.m. Big Bear search for Christopher Dorner continues amidst snow
In a noon press conference, Sheriff John McMahon said that authorities are searching about eight square miles, but have no new information on the suspect or his location. They're checking 200 empty cabins one by one, using SWAT teams.
"Our guys are making good progress at this point," McMahon said.
When asked what it would take to call of the search, McMahon said, "Some reasonable information that would suggest he's no longer in this area."
While it's snowing, McMahon said, "We can see tracks in this kind of condition." He said that snow is great for tracking, as well as seeing signs of forced entry into the various buildings in the area.
McMahon said that he met with the mayor and city manager earlier, and that they, along with Rep. Paul Cook and the board of supervisors, were supportive of the search.
"We have as many resources here as possible," McMahon said.
Big Bear Lake Mayor Jay Obernolte also spoke at the news conference. He said that the thing he's been asked the most if people in the community are panicking, and that no, they're not.
However, Obernolte added that he was more worried that someone in the community would see something and take the law into their own hands. He encouraged residents that, if they did see something, call 911 and report the incident to law enforcement.
The ski resorts are also open Friday.
"We've been assured that the suspect does not pose a substantial threat to the ski resorts or the surrounding community," Obernolte said.
"There's no information to suggest he's anywhere near the ski resort," McMahon said.
Olbernolte also thanked the law enforcement community.
"I want everyone to know you're making a big difference," Olbernolte said.
McMahon said that Dorner's burned-out truck was in the Sheriff's Department's possession back in San Bernardino. "We're turning over all the evidence and the vehicle to the Irvine Police Department."
As far as the inclement whether, McMahon said, "It's still snowing, but our folks are dressed correctly," and have the right equipment.
To get around the mountain area, authorities are using snowcats and armored personnel carriers (APCs), McMahon said. He did note that it was slower to get to areas on foot due to the weather, but that they aren't having any trouble getting to places that need to be searched.
McMahon said that the search would continue through the day and throughout the weekend if necessary.
"We have over a hundred people here again today," McMahon said. He added that they'll reassess staffing levels by the beginning of next week if the search is continuing.

UPDATE 11:45 a.m. Possible Dorner sighting turns out to be dead end
How tense is law enforcement about alleged cop killer Christopher Dorner’s whereabouts?
L.A. County Sheriff’s officials locked down Men’s Central Jail and the Twin Towers Jail in downtown around 8:45 a.m. after an employee thought she saw Dorner entering one of the facilities.
“Out of preponderance of caution, the jails and nearby courts were shut down,” Sheriff’s spokesman Steve Whitmore said. Dozens of deputies swarmed the area and searched the massive complex.
Dorner was nowhere to be found.
“It wasn’t him,” Whitmore said. He said officials still don’t know who was mistaken for Dorner.
In his online manifesto, Dorner promised "asymmetrical and unconventional warfare" against police.

UPDATE 11:40 a.m. Theories and opinions about Dorner case falling like snow in Big Bear
One of Big Bear's ski resorts is reporting a 15-percent drop in business because of the search for Dorner.
Police have made their headquarters for their search for alleged gunman Christopher Dorner at the Bear Mountain Resort. A skier at the food court, Mark Hertenstein, shared his thoughts on the hunt.
“I’m pro-gun, and everyone on the news — Obama and everyone — want to sit there and say, ‘Oh, only military and police officers should have guns,’” Hertenstein said. “Well, here’s one way of seeing not all police officers are good people. So if we’re only going to let them have guns, how is that going to necessarily stop the gun violence?”
The San Bernardino County sheriff said various reports that Dorner had been seen in the Big Bear area haven't panned out.

UPDATE 9:24 a.m. San Bernardino County Sheriff John McMahon said Friday more than 100 officers will continue searching the Big Bear area for fugitive Christopher Dorner.
Police will concentrate on the mountain above the town, where the sheriff said there are many abandoned cabins. The search will be done in snowy conditions as a winter storm is moving through Southern California.
“There are some parts of the mountain that we have not gotten to yet,” McMahon said. “We have no information that he has come down into the community.”
The search continued throughout the night Thursday into Friday morning. Officers stopped knocking on doors after midnight, but continued patrolling in vehicles, McMahon said.
Helicopters are unable to fly due to the bad weather, hampering search efforts.
The sheriff said reports that Dorner has been spotted outside of the area have turned out to be false. But he acknowledged that the fugitive has had plenty of time to leave the resort town.
In Las Vegas, FBI Agent Patrick Turner said Friday that no weapons were found after SWAT teams served a warrant Thursday at the two-story home Dorner owns about nine miles southwest of the Las Vegas Strip.
We will continue to update this story throughout the day.
UPDATE 7:24 a.m.: Police spent all night searching the snowy mountains in San Bernardino County, but didn't find Christopher Dorner, the former Los Angeles officer accused of carrying out a killing spree because he felt he was unfairly fired from his job.
Authorities plan a mid-morning update in Big Bear Lake, where Dorner's torched pickup was found Thursday.
Local ski areas are open Friday but schools are closed because of the manhunt.
San Diego County sheriff's deputies spent the night surrounding and searching a rural home after a hoaxer reported Dorner was there. It tied up 16 deputies and he was not found.
Dorner is accused of killing his former lawyer's daughter and her fiance last weekend and shooting at police officers Thursday in Riverside County, killing one and critically wounding another.
PREVIOUSLY: Law enforcement officers from several agencies continued their manhunt overnight for a former LAPD cop suspected of killing several people, including a Riverside police officer — and attempting to kill several others.
Fugitive Christopher Dorner is believed to be hiding around the resort town of Big Bear — about 80 miles east of Los Angeles, after officers discovered the charred remains of his truck in the area.
At a news conference Thursday night, San Bernardino County Sheriff John McMahon said that 125 law enforcement officers were combing the area around Big Bear Lake for Dorner as a snowstorm approached and a three-state manhunt increasingly centered on the rural mountain community. Temperatures dipped overnight in the area and snow blanketed the mountains, making the search difficult.
McMahon said deputies and officers were searching door-to-door for Dorner in the area where there are many empty vacation homes to hide in. He says the search will continue as long as conditions allow.
Speaking at a press briefing, San Bernardino County Sheriffs Department spokeswoman Cindy Bachman told reporters that schools in the Bear Valley Unified School District are expected to be in session Friday morning, and the local ski resort would reopen for business as well.
LAPD, Orange County and Sheriff's Department officers were on alert Thursday night, with officers pairing up for duty and extra police on hand to guard several LAPD buildings and area Metro stations.
The manhunt began Wednesday night, when Irvine Police announced they were searching for Dorner in connection with the murders of Monica Quan, 28, and her fiance Keith Lawrence, 27, who were shot to death in their car in an Irvine parking structure. Irvine police Chief David L. Maggard cited a manifesto Dorner is thought to have posted on Facebook outlining his motives and goals.
At about 1:30 a.m. Thursday, two LAPD officers in the Riverside County city of Corona wer fired upon after they began following a truck similar to Dorner's. Both survive, although one sustains wound to the head.
Shortly after, two other Riverside officers were ambushed at a stoplight nearby. One officer was killed. Another remains in critical condition.
Police said Dorner is highly trained and well-armed. They ask anyone with knowledge of his whereabouts to contact law enforcement officials, and not attempt to approach him.
