Killer of rookie officer had been told to give up gun

DAVIS, California — A man who shot and killed a rookie police officer in Northern California before taking his own life during a standoff with police was a 48-year-old convict who had been ordered to surrender a semi-automatic rifle.

Kevin Douglas Limbaugh’s name was released Saturday as authorities continued to investigate his motive for the attack. The Sacramento Bee reports that court documents show Limbaugh was charged and convicted in a battery case last fall, and he agreed in November to surrender the weapon.

Authorities have not determined where Limbaugh obtained the two semi-automatic handguns he was believed to have used in Thursday’s attack.

Police said a gunman on a bicycle ambushed 22-year-old officer Natalie Corona, shooting her from the shadows as she investigated a car crash.

He then walked to his house a few blocks away, chatted with his roommate and even went out to watch as police began rushing to the shooting scene, Davis Police Chief Darren Pytel said.

The gunman left behind a backpack that helped police track him to the house. The chief said as police began to surround it, he stepped outside wearing a bulletproof vest. “He shouted some stuff, went back in and came back out with a firearm, then went back inside, pushed a couch in front of the door and officers heard a gunshot,” Pytel said.
