‘We all try to make sense of the senseless’: Police search for motive in Thousand Oaks shooting

APU GOMES/AFP/Getty Images(THOUSAND OAKS, Calif.) --FBI officials swarmed the California home of Thousand Oaks shooting suspect Ian David Long on Thursday in a desperate search for motive behind his alleged shooting rampage that left 12 people dead.

Long, a former U.S. Marine, showed signs of post traumatic stress disorder, authorities said, but there's little information available yet on what prompted the attack late Wednesday at Borderline Bar and Grill. Long was found dead inside the bar; authorities believe he shot himself.

"He was somewhat irate. Acting a little irrationally," Ventura County Sheriff Geoff Dean said at a press conference. "They felt he might be suffering from PTSD, the fact he was a veteran."

Long, 28, lived with his mother, neighbors told police, describing the suspect as a troubled man who battled fits of rage.

"I think I do recall some times when he was struggling with some issues internally," said Todd Stratton, a friend of Long's. "I didn't know [about] PTSD, but his girlfriend would kind of ask him about things going on with him, because he'd get really upset sometimes and kind of shut down and he wouldn't want to talk about it to people. He'd just kind of close himself up, and I think he had a really hard time reaching out for help because of his personality."

One neighbor told ABC News she called the police on Long once after he allegedly got into a fight with his mother. Another neighbor said Long rarely left home and that his mother told her that he was getting violent.

Dean said Long had several previous run-ins with police, including an incident in April where deputies were called to his home in Newbury Park because he was reportedly behaving erratically.

"They went to the house, they talked to him. He was somewhat irate, acting a little irrationally," Dean said. "They called out our crisis intervention team, our mental health specialist, who met with him, talked to him and cleared him."

"It's difficult, because I've been doing this for 41 years, and you don't leave things unfinished," Dean, who'd been considering retirement, told ABC News' David Muir.

Dean was a close friend of one of the shooting victims, Sgt. Ron Helus, who died in the line of duty.

"I think we try to look at the core and try to understand what happened and see if there's a way that we can stop it. We all try to make sense of the senseless."

Authorities said hundreds were inside when the suspect walked in to the country-western bar with a gun and opened fire. The weapon was equipped with a an extended-ammunition magazine, allowing it to hold more than the normal 10 bullets, so it's unclear how many total rounds he may have had, police said.

Zach Frye and Tyler Odenkirk told ABC News that two of their friends who worked as security guards at Borderline were among the dead. A Borderline bouncer said they were surely among the heroes.

"I know they did everything they could in their final moments," the unnamed bouncer said. "We were told one of them went out a hero. He went out fighting the shooter."

Casey was playing with two other children, and when those kids came inside without Casey, the grandmother and others spent 45 minutes searching before calling 911, authorities said, according to WCTI.

Authorities are asking people to check their property, cars and storage sheds for Casey, the sheriff's office said.

"We want these folks in the community -- the Cayton community, the Ernul community -- to certainly keep an ear out," the sheriff told reporters. "We've got well over 100 volunteers that have come here and we don't want to utilize all of these resources at one time if come tomorrow we're still having this search and rescue effort and we've run out of resources."

Casey has blonde hair and brown eyes. He stands at 28 inches tall and weighs 25 pounds, the sheriff's office said.

Anyone with information is urged to call the Craven County Sheriff's Office at 252-633-0498 or the North Carolina State Bureau of Investigation at 919-662-4500.
