Los Angeles Police Chief Charlie Beck admitted that the Torrance shooting of newspaper delivery truck that sent two women to the hospital early Thursday morning was a case of mistaken identity in the manhunt for an ex-LAPD officer wanted for murder.

Beck said the manhunt for 33-year-old Christopher Dorner, a former LAPD officer wanted in the killings of a Cal-State Fullerton girl's basketball coach, her fiance, a USC DPS officer, and a Riverside police officer, along with injuring a slew of other law enforcement officers, may be the largest manhunt in LAPD history.

Assembly member Jose Medina (D-Riverside) released a statement regarding the death of the Riverside officer:

"I was deeply saddened to learn that a Riverside Police Officer was fatally shot and another injured today. This is a terrible tragedy, and a reminder of the dangers our police officers face every day on the job in efforts to bravely protect our families, friends, and neighbors. Police officers in California and across the country work to improve the quality of life for all of us. For that, they deserve our sincere appreciation and respect. My thoughts and prayers are with their friends and family at this time. I will ask my colleagues to join me in adjourning in memory when the Assembly meets next week."

Detectives were guarding a police official named by Dorner when a blue pickup truck matching the description of ex-cop’s 2005 Nissan Titan pulled up early in the morning with its headlights turned off. Police opened fire on the truck, riddling it with dozens of bullet holes. One delivery woman was shot in the back, the other was shot in the hand.

Both women were taken to local hospitals and have not been identified. A separate early morning shooting in Torrance resulted in no injuries and was also triggered by a similar looking vehicle.

In a 11,000 word written statement posted on Facebook, Dorner declared "unconventional and asymmetrical warfare" against his former department and outlined his unrelenting goal of taking out the families of police officials who he accuses of wronging his name. The police have said Dorner was fired for making false statements against a fellow officer.

One of Dorner's first victims, basketball coach Monica Quan, was the daughter of former police captain Randy Quan, who represented Dorner in his 2008 hearing against an officer he accused of kicking a schizophranic in the chest.

"I never had the opportunity to have a family of my own," wrote Dorner to the officers in his manifesto. "I’m terminating yours."

"Quan, Anderson, Evans, and BOR members Look your wives/husbands and surviving children directly in the face and tell them the truth as to why your children are dead," Dorner continued in his statement.

Quan and her fiancé Kevin Lawrence were found dead in their car on Sunday. They were parked on the top level of their condominium’s parking complex – a structure equipped with security cameras and key code entry. They had gotten engaged only weeks before.

On Wednesday at 10:30 a.m., Dorner attempted to steal a boat from the Southwestern Yacht Club in Point Loma late in the morning and told the boat owner that he was trying to flee to Mexico. The boat's propeller ended up getting tangled with a rope -- Dorner then tied up the man, took supplies and left in an unknown direction.

At 1:45 a.m. on Thursday, Dorner ambushed two police officers at a stoplight in Riverside, killing an 11-year-veteran of the force. Police officers in Corona responding to the shooting then got dragged down into a shootout with Dorner. One officer was grazed in the head by a bullet.
