(AP) - Court documents show an ex-girlfriend of a former Los Angeles police officer suspected of three murders called him "severely emotionally and mentally disturbed" after the two split. Documents obtained by The Associated Press on Friday show ex-officer Christopher Dorner unsuccessfully requested a restraining order against his ex-girlfriend, Ariana Williams, in 2006 after he claimed she posted his badge number on a website called Dontdatehimgirl.com and harassed him. The posting is signed "anonymous" and calls Dorner "twisted" and "super paranoid." Dorner is suspected of killing a former LAPD captain's daughter, her fiance and a Riverside police officer. He's also suspected of wounding two other officers. Dorner posted a manifesto online vowing revenge for his 2008 LAPD dismissal. Williams denied the allegations. Her attorney didn't return a call or email Friday.
