Christopher Dorner manhunt: See a timeline of key events
The reward was announced by Mayor Antonio Villaraigosa during a press conference at LAPD Headquarters. Police Chief Charlie Beck said to the force's knowledge, the $1 million reward is the largest local reward ever offered.
"We're all here for one purpose: to stand united and say that we will not tolerate a killer targeting our officers and their families, targeting innocent people," the mayor said. "We will not tolerate this reign of terror."
Ahead of that announcement, Los Angeles County Supervisors Michael D. Antonovich and Mark Ridley-Thomas announced they're offering a $100,000 reward for information leading to Dorner's capture. According to a press release, the motion will be introduced on Tuesday during the regular meeting of the Board of Supervisors. The city of Riverside and the Riverside County Board of Supervisors were also looking to add $100,000 apiece to the reward.
"This is an act - and make no mistake about it - of domestic terrorism," Beck said. "This is a man who has targeted those who we entrust to protect the public."
Around 3:30 p.m., authorities swarmed a Lowe's at 19601 Nordhoff St. in Northridge to investigate a reported sighting of Dorner. The home improvement store was evacuated and authorities made entry equipped with bullet proof vests and assault rifles. Cars were also searched in the area.
One coupe at the store said they were released from the store after three hours and at gunpoint.
"You just look to your left and you're seeing one guy with like an M16, you're seeing another guy with a shotgun, two pistols, and you're just like, wow, this is serious," said David McLean, who was at the store.
Authorities said they received two reports from two different callers about seeing Dorner on the store's property. A few hours later, the scene was cleared.
LAPD Lt. Ahmad Zarekani said every call would be checked out. There have been several false alarms.
Also Sunday, authorities said the search in the Big Bear area, the focus for the past several days, would be scaled back.
It was announced that all schools in Bear Valley Unified School District will be open Monday and will have extra security.
Saturday, authorities announced that a task force has been assembled to track down Dorner. The task force includes the Los Angeles, Irvine and Riverside police departments, along with the FBI and U.S. Marshals, and other allied law enforcement agencies in the region.
It was also announced that the LAPD planned to reopen the investigation into the disciplinary proceedings that led to the firing of the 33-year-old ex-cop. The firing apparently led Dorner to seek revenge against former LAPD colleagues who he believed cost him his law enforcement career.
In a lengthy manifesto he posted online, Dorner claims he was wrongfully fired because he reported that his training officer used excessive force in arresting a mentally ill man back in 2007. The department reviewed that incident and found that Dorner lied and fired him. Now, the department says they will re-interview everyone involved - not as a way to appease Dorner but to restore the public's trust.
Also Saturday, sources told Eyewitness News that two AR-15 rifles were found in Dorner's truck in Big Bear, and the truck had a broken axle. Sources also said that Dorner had a storage locker in Buena Park. A search warrant was served at the storage facility and it was searched Friday night. Irvine police said evidence was obtained from the location, and the scene has since been cleared.
Investigators would not say who was leasing the unit or what they confiscated. However, the storage facility's owner said the storage unit may have belonged to one of Dorner's relatives.
On day four of the manhunt, San Bernardino County Sheriff's officials say about 25 law enforcement officers are searching the forest and conducting door-to-door checks of unoccupied vacation homes, rentals and cabins. A helicopter is also providing aerial support.
Dorner's online manifesto declares war against the LAPD. He shot at several officers already, killing one on Thursday.
Later that day, Dorner's Nissan truck was found in the Big Bear area. The vehicle was abandoned and burned. An extensive search has been going on ever since.
Thursday, investigators discovered some footprints near the scene of the burned Nissan, but those were ruled out after authorities determined they came from a cross-country skier. Investigators also found a kicked-in door in one of those abandoned cabins, but they ruled that out as old damage. Also, Dorner's mother owns undeveloped land in Arrowbear, about 35 miles from Big Bear. No clues turned up there either.
Dorner is suspect in double murder, police shootings
Dorner is suspected of opening fire on three police officers in the Inland Empire on Thursday, killing one.
The slain officer was 34-year-old Mike Crain, an 11-year veteran of the Riverside Police Department. Crain was killed in the line of duty when he and his partner were ambushed while on routine patrol. The second officer was seriously wounded. A fund was set up for anyone wishing to make a donation Crain's family.

The chain of events began Sunday after an Irvine couple, Monica Quan and Keith Lawrence, were found shot to death inside a car in the parking garage of their apartment complex. Quan is the daughter of an LAPD captain who represented Dorner during disciplinary hearings, which resulted in his dismissal from the department.
ABC News has learned that a man claiming to be Dorner called Randy Quan to taunt him. It was made four days after the murder of his daughter, Monica Quan.

Dorner implicated himself in the weekend retaliation murders in his manifesto.
New surveillance video shows a man believed to be Dorner dumping items in a garbage bin, including an ammo magazine and a military belt. It was taken Monday, one day after the murders of Quan and Lawrence, outside an auto parts shop in National City, south of San Diego.
Authorities emphasize that Dorner is armed and considered extremely dangerous. If seen, do not attempt to contact him and call 911.
