Davis police investigators said they recovered evidence from the rental property of the man who shot and killed one of their officers Thursday, including a note they believe was written by the man and two guns that were not registered to him.
On Saturday, police released a one-paragraph letter they said was written by Kevin Douglas Limbaugh. Spokesman Lt. Paul Doroshov told reporters that the paper was found face up on the bed of the gunman. The letter reads:
“The Davis Police department has been hitting me with ultra sonic waves meant to keep dogs from barking. 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.”
The simple printed statement was signed “Citizen Kevin Limbaugh.”

In addition to the letter, investigators recovered two semiautomatic handguns inside the house, a 9 mm and a .45-caliber, Doroshov said. Police are checking who registered the guns.
The weapons’ profile matches witness descriptions of the firearm Limbaugh used to kill Davis officer Natalie Corona in an ambush-style attack on Thursday.
The 48-year-old man was ordered last fall to surrender a semiautomatic rifle after he was convicted in a battery case, stemming from an incident in which he punched a co-worker in the face after a dispute, one of several incidents before he opened fire on Corona, a 22-year-old officer who had served with the force less than a year.
