Corona was the first Davis police officer killed in the line of duty since Douglas Cantrill was gunned down Sept. 7, 1959, the Bee reported.
Police surrounded a home several blocks from the shooting scene and tried to coax the man out of the building, the newspaper reported.
At 1:30 a.m. Friday, police announced that the shooter had been found dead from what appeared to be a self-inflicted gunshot wound, KOVR reported.
Davis police did not identify the suspect, other than to describe him as a white male in his 20s with an average build and wearing a baseball cap, black jacket and black tactical boots, the Bee reported.
Corona started with the Davis Police Department as a community service officer, the Bee reported. She was sworn into the department on Aug. 2 and her father pinned her badge, according to the Williams Pioneer.
