A former Los Angeles police officer may be making good on his threats against other officers.
Police believe Christopher Donner ambushed two police officers early Thursday in a Los Angeles suburb, killing one of them.
He'd already been the main suspect in the weekend killing of a couple whose bodies were found in Irvine.
Police say he implicated himself in those killings in a "manifesto" that included threats against members of the LAPD and others.
Donner was fired from the force in 2008 for making false statements.
LAPD Capt. William Hayes tells The Associated Press on Wednesday night that Donner was represented by one of his victim's father, Randal Quan.
Quan, a former LAPD captain who became a lawyer in retirement, represented Donner in front of the Board of Rights, a disciplinary tribunal that ruled against Donner when he was dismissed.
Quan is the father of 28-year-old victim Monica Quan, who was shot along with her fiance, Keith Lawrence, on Sunday.
Officials say a New Jersey man has died from injuries he suffered in a chain-reaction crash inside one of the tubes of the Lincoln Tunnel. Port Authority of New York and New Jersey police spokesman Joe Pentangelo says the 49-year-old Summit resident was among three people hurt in the accident.
