Suicidal man who killed officer said he was hit by ultrasonic waves

DAVIS, Calif. — The man who shot and killed a rookie California police officer left a letter on the bed in the home where he lived claiming police bombarded him with ultrasonic waves, officials said.

Police in the college town of Davis near Sacramento on Saturday made public the one-paragraph letter they said was written by Kevin Douglas Limbaugh, 48. He killed himself Thursday after fatally shooting Officer Natalie Corona.

Police spokesman Lt. Paul Doroshov said the paper was found face up on the gunman’s bed.

“The Davis Police department has been hitting me with ultra sonic (sic) waves meant to keep dogs from barking,” the letter said. “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 handwritten note was signed “Citizen Kevin Limbaugh.” Also recovered as evidence from the man’s home were two unregistered guns.
