What we know about Thousand Oaks gunman Ian David Long, a Marine veteran

NEWBURY PARK, Calif. – Sunny Southern California weather has a way of making all neighborhoods look idyllic.

But in one such Los Angeles-area home, a ranch-style house in a pleasant, leafy enclave, lurked a profound darkness. Inside 804 Fowler Ave. lived a troubled man whose rages created booming noises and summoned local police.

Marine Corps veteran Ian David Long, 28, the man accused of killing 12 at a nearby country bar late Wednesday before shooting himself, was a former machine gunner and decorated combat veteran of the war in Afghanistan who, authorities said, had an episode of erratic behavior last spring that suggested post-traumatic stress disorder.

Long’s various interactions with police over the years pointed to a man who needed professional help. None came.

Neighbor Richard Berge said everyone on the block was aware when the police came to the Long home earlier this year after an incident.

Neighbor Richard Berge said everyone on the block was aware when the police came to the Long home earlier this year after an incident.

“Police were here, and they finally get (Long) to come out of the house,” Berge told USA TODAY Thursday as FBI agents shuttled in and out of the home Long shared with his mother, Colleen.

Berge described Long’s mother as “a very nice lady” – he got to know her after offering to care for one of the family’s combative German shepherds – who was frustrated her son wasn’t seeking help for his condition.

Although Berge had never been inside the Long house, he said a neighbor had reported seeing walls that were “full of holes,” adding that the neighbor got the impression that Long had kicked the walls in.

“She was worried because he wouldn’t get help,“ Berge said. “I asked her, ‘Can’t he just get help.’ She said, ‘He can’t get help.’”

Longtime neighborhood resident Donald MacLeod, 79, shares a back wall with the Long residence. He says he often heard the volatile adult son arguing with his mother at all hours, sometimes “in the middle of the night, at 2 a.m.”
