The gunman who killed 12 people at the Borderline Bar & Grill in Thousand Oaks, California, was a 28-year-old veteran of the US Marine Corps, officials said.
Here's what we know about shooter Ian David Long so far:
- He had previous run-ins with the law: In April, officers responded to a disturbance at Long's home, and he was irate and acting irrationally, said Ventura County Sheriff Geoff Dean.
- He was in the Marine Corps: Long was on active duty from August 2008 to March 2013, according to Defense Department records.
- He lived with his mother: A neighbor told CNN that Long's mother "lived in fear" of what her son might do, saying when police were called to the house earlier this year "it took them about a half a day to get him out of the house."
- He was divorced: Long got married in 2009 in Honolulu, Hawaii, but got separated in 2011 and dissolved the marriage in April 2013 in Ventura County, California. They had no children and owned no property.
- He is believed to have killed himself: His body was found inside the bar when police were able to enter the building.
- He used to frequent Borderline Bar & Grill: The bar was the site of the deadly shooting. One of Long's old friends, who declined to be identified, said, "He was a part of that community."
- His friends describe him as "a very stable man." Mark Waid, one of Long's high school friends, told CNN, “The Ian I knew would not do this." Three other friends, who declined to be identified, also expressed surprise. One commented, "I don’t know what the hell happened."
