THOUSAND OAKS, Calif. (AP) The mayor of Thousand Oaks, Calif., says next-of-kin notifications are being prepared about the people who were killed and injured at the mass shooting inside a bar in the city.
Mayor Andrew Fox says it is going to be a "very difficult day for many people."
The gunman who killed 12 people at a Southern California bar was a Marine who served one combat tour in Afghanistan.
The Marine Corps says 28-year-old Ian David Long was deployed to Afghanistan for seven months, from Nov. 16, 2010, to June 14, 2011.
He was in the Marines from August 2008 until March 2013, serving as a machine gunner and earning the rank of corporal in August 2011.
The Marine Corps says Long earned several awards, including a Combat Action Ribbon and a Marine Corps Good Conduct Medal.
He was assigned to the 2nd Battalion, 3rd Marine Regiment, Third Marine Division in Kaneohe Bay, Hawaii.
Authorities confirmed Sgt. Ron Helus responded to the scene and was shot after he entered the building.
He died at a hospital early Thursday.
Helus was married with a grown son.
Ventura County Sheriff Geoff Dean says the report of the shooting came as Helus was on the phone with his wife.
The sheriff says Helus told her, "Hey I gotta go handle a call. I love you. I'll talk to you later."
President Donald Trump has ordered that the U.S. flag be flown at half-staff in respect for the victims of the shooting at a bar in Thousand Oaks, California.
Trump ordered the flag be flown at half-staff until sunset Saturday at the White House and on all public buildings, military posts, naval stations and aboard all U.S. naval vessels.
He also directed the flag to be flown at half-staff at all U.S. embassies and military bases and naval stations abroad.
"Sister Sister" actress Tamera Mowry-Housley and her husband are looking for their missing niece following the mass shooting at the Southern California bar.
A suite mate of the couple's niece, Alaina Housely, went on Twitter to say her friend was missing and offered a description of what she was wearing.
Mowry-Housley responded by identifying herself as Housley's aunt and sought to contact the suitemate directly.
The bar's website says its hosts "College Country Night" every Wednesday. Police said hundreds were inside when the shooting.
The bar is popular with students at Pepperdine University in Malibu, which is about 25 minutes south of Thousand Oaks.
Baylor University President Linda Livingstone, who spent 12 years as dean of Pepperdine’s Graziadio School of Business and Management, issued a statement Thursday expressing sympathy to the victims and their families.
“As senseless tragedy has once again struck our nation in California, our hearts ache and our prayers go out for the victims – many of them college students in the venue – and their families,” she said.
“As a former resident of the area, mother of a college student and president of a university committed to creating a safe environment for our students, I am even more mindful of our responsibility to care for one another and illustrate God’s love in our actions every day. May we lift our prayers as a community for those whose lives have been impacted by this tragedy and for God’s peace to prevail across our country.
