(NBC) - More than a thousand officers have joined in the massive manhunt to capture former Los Angeles Police officer and accused murderer Christopher Dorner.
His burned out truck was found Thursday afternoon in the mountains two hours east of Los Angeles, but Dorner is still nowhere to be found.
A former Navy reservist and expert marksman, Dorner posted a lengthy manifesto on Facebook detailing threats against two dozen police officers he intended to kill.
He claimed he was treated unfairly when he was fired from the L.A. Police Department in 2008 for making false statements.
Dorner filed a wrongful termination suit against the LAPD, but lost the case.
His killing spree began Sunday when the daughter of the LAPD captain who represented Dorner in his suit was found dead along with her fiance.
Police say on Thursday morning Dorner shot and injured an officer and then shortly after, ambushed two more at a traffic light, killing one.
During the morning chaos police mistakenly shot and wounded two women delivering newspapers when the officers thought they had spotted Dorner's truck.
