FILE - In this Thursday, Nov. 8, 2018, file photo, Colleen Long, mother of shooting suspect David Ian Long, leaves her house in Newbury Park, Calif. If authorities have concluded why Ian David Long shot and killed 12 people at a Southern California bar, they aren't sharing, and his family isn't talking, either. That has left a community still in mourning to wonder why, but also ask who was the man who shattered the sense of security in the Los Angeles suburb of Thousand Oaks? (AP Photo/Jae C. Hong, File)
