Ian David Long shot 12 people inside a Thousand Oaks, California college bar before dying of his own wounds, and used an illegal extended magazine, police said.
Long fought with police for over an hour and fired dozens of shots, according to witness reports.
Long’s gun was one of the most popular handguns in the US today, and the extended magazine he used is widely available across the states, though not in California.
While most gun control debate centers around long guns and rifles, the vast majority of gun violence happens with handguns.
Long’s violent spree on Wednesday night shows how much damage one person with a pistol can do.
Ian David Long, the man police say shot 12 people inside a Thousand Oaks, California college bar before dying of his own wounds, used an illegal extended magazine that allowed his gun to hold more bullets as he waged a gunfight and standoff with police that lasted over an hour, police said.
Witnesses to the shooting reported hearing at least a dozen shots while fleeing the bar. A police spokesman said that authorities responded to a call of shots fired and showed up around three minutes later and still heard shots going off.
Ventura County deputy sheriff Sgt. Ron Helus rushed into the bar while shots were still going off and was struck “multiple times by gunfire,” according to police. Helus, along with 11 others, later died of his wounds.
The Thousand Oaks shooting will go down as tied for the 15th deadliest US shooting on record, but unlike the Las Vegas shooting, which affected many of the exact same people, only one commonly available handgun was used.

Police at the scene found just one handgun, Sheriff Geoff Dean, who responded to the incident, told the “Today” show.
When asked on the show if he thought it was unusual “that a handgun could cause that much damage that quickly,” Dean said he wasn’t surprised.
“Assault rifles get all the attention but certainly a handgun in the hand of the right person can certainly wreak a lot of damage, especially at close range.”
Long, a veteran of the Marine Corps, would have had training with firearms. Long used a Glock .45, which fires one of the largest-caliber bullets commercially available.
The factory-standard magazine on Long’s Glock likely held 13 rounds, and the gun can accommodate another round loaded into the chamber and ready to fire.
But Long had an extended magazine, according to police. Extended magazines available for sale on the Long’s model of Glock can hold 21, 30 or more rounds.

The modification is illegal in California
California has passed a series of laws outlawing the sale of extended magazines, which they consider “any ammunition feeding device with the capacity to accept more than ten rounds” in calibers above .22.
