An internal review by the Los Angeles Police Department concluded that rogue ex-officer Christopher Dorner was justifiably fired, a lawyer who reviewed the findings told The Associated Press on Tuesday.

Civil rights attorney Connie Rice said the lengthy examination found no basis for allegations of racism and bias that Dorner made in a manifesto vowing revenge on his former colleagues and their families.

Authorities said Dorner killed four people, including two law enforcement officers, during a weeklong rampage in February that involved a massive manhunt and ended with his apparent suicide in a mountain cabin following a gunbattle with police.

The findings, which are expected to be made public this month at a Los Angeles Police Commission meeting, concluded that Dorner had a history of embellishing stories, misperceiving slights and making bogus complaints against his fellow officers, Rice said.

He took more than twice as long as most officers to complete his training, was nearly incomprehensible during the hearing over his firing, and only filed a complaint against his training officer when he learned she gave him a bad performance review, Rice said.

The department said in a statement the review had not been finalized.

"Any comments or conclusions about the contents of the review are premature," it said. "The LAPD will announce the review once finalized."

Police Commission President Andrea Ordin said the report still needed to go to the inspector general for review and then to the Police Commission.

Chief Charlie Beck ordered the review as Dorner was on the run after being accused of killing the daughter of his former union lawyer and her fiance and releasing the manifesto saying he would get even for being unfairly fired because he was Black.
