The guns he used in the killings last Friday were stashed inside his apartment at the time, but police never searched the residence or conducted a check to determine if he owned firearms because they didn't consider him a threat.
The statement does not explain why the videos were not viewed or whether the deputies knew anything about the contents beyond a description of them being "disturbing."
The sheriff's department also revealed new details about the timeline leading up to the killings. It said Rodger uploaded his final video to YouTube detailing his "Day of Retribution" and stating his plans and reasons for the killings, at 9:17 p.m. on the day of the shootings, May 23. One minute later, he emailed a lengthy written manifesto to his mother, father and therapist that also detailed his plans and contempt for everyone he felt were responsible for his sexual frustrations and overall miserable existence.
The first gunshots were reported at 9:27 p.m. The rampage was over and Rodger dead just eight minutes later.
It was another half hour before the therapist saw the emailed manifesto and 11 more minutes until the sheriff's office was contacted at 10:11 p.m. Authorities contacted Rodger's mother and learned about the manifesto and the "Retribution" video.
