CA Cop Killer Complained of ‘Ultra Sonic Waves’

Man who killed a rookie Davis, Ca., police officer left a note saying that police had been “hitting me with ultra sonic waves meant to keep dogs from barking.”

A man identified as the gunman in the ambush killing of a Davis, Ca. police officer left a note in his apartment saying that police had hit him with “ultra sonic waves meant to keep dogs from barking,” the San Francisco Chronicle reports. Kevin Douglas Limbaugh, 48, was identified as the man who shot and killed officer Natalie Corona, 22, on Thursday while the rookie officer was responding to a routine collision. Hours after the shooting, Limbaugh killed himself with a single gunshot to the head as police closed in, said Davis Police Chief Darren Pytel.

“The Davis Police department has been hitting me with ultra sonic waves meant to keep dogs from barking,” read the note, which was typed on a computer. “I notified the press, internal affairs, and even the FBI about it. I am highly sensitive to its affect (sic) on my inner ear. I did my best to appease them, but they have continued for years and I can’t live this way anymore.” Davis police Lt. Paul Doroshov said it is not clear when the note was typed. “There have been a lot of rumors as to why this happened, why he did what he did, and we’re hoping this sheds some light,” Doroshov said. The note was found on Limbaugh’s bed. The killing of Corona and a shooting spree that followed was not Limbaugh’s first brush with the law. In September, he was arrested on a felony charge of battery with serious bodily injury. The charge was reduced to a misdemeanor in a plea deal, resulting in an eight-day jail sentence. He was ordered to surrender a semiautomatic rifle, not the weapon used in the police killing, the Sacramento Bee reports. The charge stemmed from his punching a co-worker at a casino in the face.
