The man suspected of shooting and killing a young Davis police officer just before 7:00 p.m. last Thursday reportedly allegedly thought police were targeting him with 'sonic waves' for years.
Kevin Douglas Limbaugh, 48, was identified on Saturday as the man believed to have ambushed Officer Natalie Corona, 22, while she investigated an unrelated traffic accident near 5th and C streets in downtown Davis.
Investigators on Saturday also released a printed letter inside Limbaugh's home that appears to written by him.
"The Davis Police department has been hitting me with ultra sonic waves meant to keep dogs from barking," he allegedly says in the letter. "I notified the press, internal affairs, and even the FBI about it,” the note continued. “I am highly sensitive to its affect 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."
Speaking for the Davis Police Department, Lieutenant Paul Doroshov said no complaints had ever been received from Limbaugh.
Limbaugh also had a criminal history. In September 2018, he was charged with battery resulting in serious injury, according to Yolo County court documents. Davis police say the charge stemmed from an assault on a co-worker at the Cache Creek Casino Resort. Limbaugh was reportedly fired after that incident.
Doroshov noted that the charge was eventually reduced to a misdemeanor during the court proceedings. Therefore, Limbaugh had no criminal record, but he had file a stolen-vehicle report with the department in the past.
Limbaugh also surrendered to authorities an AR-15 rifle per the terms of his assault plea deal. However, authorities said that neither that rifle nor the two hand guns and ammunition alleged to have been used in the Thursday shooting spree were registered to Limbaugh.
On the night of the shooting Limbaugh is said have targeted other first responders after shooting Corona multiple times at close range. She was transported to UC Davis Medical Center last night, but ultimately died of her wounds. While one firefighter was struck in his boot by a bullet, he was not injured. No one else was hurt in the shooting, though several bullets struck nearby vehicles, a home, and a backpack reportedly worn by a person walking in the area.
Pytel was somewhat emotional as he noted that Corona went to ground after taking a bullet to the neck-- she was wearing a bullet proof vest at the time of the shooting. However, once she was down the gunman fire several more shots at the young officer at close range, according to Pytel.
Authorities said 22-year-old Natalie Corona had just begun investigating the three-car accident when a suspect, who is still unidentified, opened fire. That suspect is only described as a white male in his 20s. The release of his name is pending completion of work by the coroner's office and may not happen until next week.
Authorities eventually located him in a home near where the shooting took place just before 1 a.m. Friday. Pytel also said a robot was sent into house after officers heard shot. That is when they discovered him dead from an apparent self-inflicted gunshot wound. He has still not been identified.
Officials say Corona was the daughter of a retired sheriff's deputy and a rising star at the David Police Department.
Governor Gavin Newsom has ordered state Capitol flags flown at half-staff in tribute to Corona. Newsom said he and his wife, Jennifer, are saddened by the death of a woman he called "courageous" who died "protecting her protecting her community from harm."
Los Angeles Police Chief Michel Moore tweeted on Friday that his and the LAPD's thoughts and prayers are with Corona's family.
Corona had reportedly been hired on a part-time basis at the Davis Police Department in 2016. She had completed her police academy training in July and finished field training just before Christmas. The young had only been working on the streets of Davis for a matter of weeks before this incident.
