UPDATE: President Donald Trump is blaming mental illness for the California bar shooting that left 13 people dead, including the shooter.
    
Trump, speaking to reporters at the White House on Friday, described gunman Ian David Long as "a very sick puppy" who had "a lot of problems."
    
Long, who opened fire at the country music bar in Thousand Oaks on Wednesday, was seen by a mental health specialist in April who worried the 28-year-old Marine veteran might have post-traumatic stress disorder. Investigators have not commented on a motive for the shooting, or whether mental illness played a role.
    
Trump touted his efforts to fund PTSD among veterans. But he declined to engage on questions on whether the nation needed stricter gun control laws.
    
Trump has closely aligned himself with the powerful gun lobbying group, the National Rifle Association, and has resisted calls for tougher firearms measures.

A Navy veteran, an art student, and a bouncer were some of those killed in the bar attack.

One was a veteran police officer who didn't hesitate to run toward danger. Another was an art student who worked with children at her church. Others were a Navy veteran, an a cappella singer who worked as a caregiver, and a security guard with a "big personality" who was known for making sure everyone got home safely.
    
They were among a dozen people killed in a shooting at a country music bar in Southern California. Authorities believe the gunman , Ian David Long, ultimately killed himself.
    
The victims' stories began to emerge Thursday. It was going to be a "very difficult day for many people," said Andrew Fox, mayor of Thousand Oaks, California, where the attack happened Wednesday night.

An FBI official says investigators seeking the motive for the mass shooting at a Southern California bar hope evidence will allow them to paint a picture of the gunman's frame of mind.

Paul Delacourt, assistant director of the Los Angeles field office, says the crime scene, the gunman's home and car are being processed for evidence and interviews are being conducted.

But he says it's premature to speculate on the motivation.

Earlier, Ventura County Sheriff Geoff Dean identified the shooter in Wednesday night's mass shooting that killed 12 people at a bar in Thousand Oaks. 

Sheriff Dean says 28-year-old Ian David Long was armed with a Glock 21, a .45-caliber handgun designed to hold 10 rounds plus one in the chamber.

But the sheriff says the gun had an extended magazine that is illegal in California. The sheriff says he does not know how many rounds that magazine can hold.

Deputies believe Long killed himself. His body was found inside the bar when officers entered the building. 

Dean says his department had several previous contacts with the former Marine including a call to his home in April, when deputies found him acting irate and irrationally.

The sheriff says a mental health crisis team was called at that time and concluded that Long did not need to be taken into custody.

Dean says the other prior encounters were a traffic accident and an incident when he was the victim of a battery at a bar.

Sheriff Dean says sheriff's Sgt. Ron Helus responded to the scene and was shot after he entered the building. He died at a hospital early Thursday.

Ventura County Sheriff's Office Capt. Garo Kuredjian said the first reports of shots fired came around 11:20 p.m. 

The bar's website says its hosts "College Country Night" every Wednesday. Police said hundreds were inside when the shooting occurred.

Authorities and witnesses say the gunman wore dark clothing and didn't say anything as he fired inside the bar. Hundreds of people fled, some breaking windows and jumping out of second-floor windows to escape.

President Donald Trump is offering condolences after a mass shooting at a Southern California bar.

    
Trump said on Twitter Thursday that he has been "fully briefed on the terrible shooting." He praised law enforcement, saying "Great bravery shown by police" and said "God bless all of the victims and families of the victims.

California Lutheran University has canceled classes for Thursday. 

The Cal Lutheran website says the university community is invited to gather at the school's chapel.

The university is a short drive from the Borderline Bar & Grill.

Cal Lutheran has more than 3,000 undergraduate students and more than 1,300 graduate students.

The bar is also close to several other universities, including California State University Channel Islands in Camarillo, Pepperdine University in Malibu and Moorpark College in Moorpark.
