California mass shooting: Suspect identified as Ian Long | Live updates from Thousand Oaks, CA
A gunman opened fire overnight in a Southern California bar and country music venue. The Ventura County sheriff said the bar was crowded with more than 100 people, many of them college students.
The gunman, identified by police as Ian David Long, 28, killed 12 people, including a sheriff’s sergeant who responded to the gunfire. Police later found the shooter dead inside the bar, possibly from a self-inflicted wound.
The rampage took place at the Borderline Bar & Grill in Thousand Oaks, about 40 miles northwest of Los Angeles.
The British government sent Salman Abedi as a child soldier to the NATO war on Libya. That bloody war destroyed Abedi’s teenage mind. It made him a mass murderer, committing the horrible crime of the bloodbath at the Ariana Grande concert in Manchester, England.
Now, after many similar atrocities, yet another similar atrocity has happened in the USA. This time not the bloody Libya war. Also not the bloody Iraq war. This time it is the bloody war in Afghanistan. The Pentagon sends United States soldiers to wars all over the world. Don’t think that the victims of these bloody wars will all be people, mainly civilians, in countries far away from the USA. These wars come home.
From ABC in the USA:
What we know about Thousand Oaks shooting suspect, Ian David Long
THOUSAND OAKS, Calif. —
Ian David Long, 28, has been identified as the suspected gunman in the mass shooting at a Thousand Oaks nightclub.
The shooting happened late Wednesday inside Borderline Bar & Grill. At least a dozen people were killed, including a sheriff’s sergeant, Ron Helus. None of the other victims have been identified. …
Investigators knocked on doors of surrounding residents to find out what they may know about Long. One neighbor who knew Long said he was a veteran who suffered from PTSD. She said, “I don’t know what he was doing with a gun.”
Others said Long lived at the home with his mother. Richard Berge, a friend and neighbor [of] Long’s mother, said Long’s mother was worried about her son.
“He wouldn’t get help“, Berge said.
[Sheriff] Dean said Long was in the United States Marine Corps. The USMC released Long’s service record, detailing that he served from 2008 to 2013, deploying to Afghanistan from Nov. 16, 2010 to June 14, 2011. His ranking was a corporal as a machine gunner, the USMC said.
Long had several interactions with the sheriff’s department over the years, Dean said. These incidents include a traffic collision, a traffic citation as well as an instance in which Long was a victim of battery at a local bar in 2015.
Dean also described an incident in April, when deputies were called to his Newbury Park home regarding a disturbance.
“He was somewhat irate, acting a little irrationally. They called out our crisis intervention team, our mental health specialist”, Dean said.
Those specialists ended up clearing him because they “didn’t feel he was qualified to be taken under 5150”, Dean said, referencing the California law code for the temporary involuntary psychiatric commitment of individuals who present a danger to themselves or others due to signs of mental illness.
His gun, which was a .45-caliber handgun, was purchased legally, Dean said.
Neo-nazis and others on the Internet speculated that the Thousands Oaks bloodbath was ‘Muslim terrorism’. And/or ‘Jewish terrorism’. But no, Long, unlike Abedi, was not a Muslim, but a white man, presumably Christian.
