Cop killer blamed ultrasonic waves
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 Davis on Saturday made public the oneparagraph letter they said was written by Kevin Douglas Limbaugh, 48. He killed himself Thursday after fatally shooting Officer Natalie Corona.
“The Davis Police department has been hitting me with ultra sonic (sic) waves meant to keep dogs from barking,” Limbaugh said in the letter.
