Sunday, Feb. 3, 2013: Monica Quan, 28, daughter of an ex-LAPD captain who Christopher Dorner apparently believed represented him poorly before LAPD fired him, is slain along with her boyfriend Keith Lawrence, 27. The bodies are found in a car in their condo's Irvine parking garage. Quan was an assistant women's basketball coach at California State University, Fullerton. Lawrence was with security at USC.
Monday, Feb. 4: About 9:30 a.m., authorities discover “police equipment” belonging to Dorner — reported by some media to be his disgraced LAPD badge — tossed into a Dumpster near the National City Police Department in a suburb of San Diego.
Wednesday, Feb. 6:
–At 8:15 p.m., Irvine Police Department reveals that it believes fired LAPD officer Christopher Dorner slaughtered newly engaged Monica Quan and Keith Lawrence on Feb. 3 inside a secure, key-card only condo garage in ultra-safe Irvine, which has had only two murders in the past year. Describing Dorner as armed and dangerous, police say he had posted a “manifesto” on his little-noticed Facebook page that vowed to carry out killings of people and families connected to LAPD. Quan's father, an LAPD captain, had argued on behalf of Dorner years earlier when Dorner was fired by a Board of Review.
–At 9 p.m., KCAL news reports that LAPD Chief Charlie Beck is being protected as a result of the hit list contained in the manifesto.
— At about 10:30 p.m., two hours south of Irvine in San Diego, a large black man matching Dorner's description ties up an 81-year-old man at Southwestern Yacht Club after demanding a boat ride to Mexico. The suspect tries to steal the man's 47-foot cruiser, but, according to officials, either the engine won't start or a rope gets tangled around the propeller. The suspect flees.
Thursday, Feb. 7:
— At around 1:30 a.m. in Corona, about 90 minutes from San Diego, two LAPD officers sent there to protect somebody who'd been named on Dorner's Facebook hit-list are alerted by a resident that a truck matching Dorner's description is nearby. They chase the truck and a gunfight erupts in which one LAPD officer is grazed on the head. The gunman, believed to be Dorner, gets away. Shortly after that, Dorner allegedly spots and ambushes two uninvolved Riverside cops as they wait at a red light on a typical patrol night. One Riverside officer, 34, is murdered, the other, 27, is badly hurt but will recover.
— About 2:20 a.m., Dorner's wallet containing some type of badge and positive picture ID for Dorner are turned into San Diego PD after being discovered by a passerby who found them thrown away near Lindbergh Field along Harbor Drive in San Diego.
— About 5:20 a.m., LAPD officers guarding one of Dorner's hit-list targets in low-crime Torrance in suburban Los Angeles become unnerved when they see a truck similar to Dorner's whose driver stops and throws things from the window. At least one LAPD officer opens fire — shooting two innocent newspaper delivery women, one of them allegedly in the back. Not long after that, spooked local Torrance police also open fire after mistaking yet another truck for Dorner's. Luckily, nobody gets shot by the suburban cops.
–About 8:30 a.m., media reports indicate that authorities may be investigating a burned-out truck found near the Bear Mountain ski area near Big Bear. Crack teams of sharpshooters are reported landing in aircraft nearby with weapons already drawn. Schools in the Bear Valley Unified School District are on lockdown and the ski area closes due to police activity. Meanwhile, the manhunt for Dorner widens beyond California and Nevada as law enforcement in Arizona are alerted to the vehicle's description.
— About 9:40 a.m., somebody at Naval Base Point Loma in San Diego reports seeing Dorner, a Naval Reserve officer, on the base. Base personnel confirm he checked into, but never checked out of, an on-base hotel, Navy Gateway Inns & Suites. After a massive search and rare lock-down in which base personnel were ordered to remain in their homes, Navy officials announce they have found nothing.
— About 2:30 p.m., authorities confirm their first major break in the manhunt: The burned-out pickup truck found near Bear Mountain ski area at Big Bear Lake belongs to Dorner. Nervous area residents begin wait amidst high tension as reports surface that police hope to catch him before nightfall, when the search will become more difficult and more dangerous.
— About 3:30 p.m., at a jammed news conference, San Bernardino County Sheriff John McMahon announces that a door-to-door search of the quiet mountain resort community has been launched.
