Men in green sheriff's vests led families into the Reunification Center in Thousand Oaks on Thursday, their faces veiled in caps, hoodies and flannels to block members of the press, watching from behind yellow caution tape. Inside, families learned whether their loved ones had been killed in the deadly shooting in Thousand Oaks on Wednesday night. Outside, a woman in a white clinical coat led a white emotional support horse to families who were huddled together. Two men hugged a woman who had fallen to the ground, overcome with tears.

Despite the media presence outside, the center was eerily quiet.

Twelve people were killed and 22 were injured when a gunman opened fire on Borderline Bar & Grill in Thousand Oaks, Calif. The gunman was also killed. Typically, Wednesday nights are College Country Nights, where students listen to country music and line-dance with their friends. Any student 18 and older can attend college nights, and they are very popular among California Lutheran University, Pepperdine University and Moorpark College students.

The identities of the 12 victims have been confirmed by friends and family, and the Ventura County Sheriff's Department has confirmed the death of Sgt. Ron Helus, who had responded to the shooting. Of the other victims who have been identified, seven were students.

"Sgt. Ron Helus donned his uniform yesterday as he did for the past 29 years," LAPD tweeted on Thursday alongside photos of Helus' funeral procession. "When gunfire erupted, [he] feared no evil, rushing to unselfishly protect his community."

Helus is survived by a wife and a son, according to The Ventura County Sheriff's Office.

"He loved spending time with his son," Sgt. Eric Buschow told CNN. "They would go fishing up in the Sierras together."

"Pepperdine's theater community is really hurting because Alaina was a participant in the choir," Isabel Klein, a senior at Pepperdine, said. She and Housley had many mutual friends. "At the school's prayer service, when they said her name, everyone gasped."

"She had such an infectious smile," Pepperdine University President Andrew Benton told ABC 7. "Her light will shine on, we will be sure of it."

Simi Valley native Kristina Kaylee Morisette was a Borderline Bar & Grill employee. Photos show the victim smiling and holding a waitress tray in a "Borderline" t-shirt.

"My sweet, beautiful cousin Kristina Kaylee Morisette was taken from our family last night in another senseless shooting," Scott Evert wrote on Facebook. "She will be deeply missed."

Evert's wife echoed his sorrow.

"We love you, Kristina Kaylee Morisette," she wrote.

Reactions from USC and around the World

USC Provost Michael Quick emailed a university-wide memorandum offering condolences to those affected by the shooting.

"Reports suggest many of the victims are college-age, which makes this latest shooting hit even closer to home," he wrote. "I know many of you are tired and angry, and I share those feelings."

The memorandum concluded with numbers of counseling services and crisis support hotlines.

U.S. Sen. Dianne Feinstein of California also expressed her condolences, saying she is "heartbroken." She also called for "stronger federal gun regulations" in a written statement.

"These mass murders are depressingly pervasive," Feinstein wrote. "They're inspired by racism, revenge, terrorism or just pure hatred. The one common attribute: easy access to guns."

Local students responded to the divisive issue of gun control differently after Wednesday's shooting.

"I am a firm believer that there should be gun control," said Melissa Dennin, a freshman at Cal Lutheran who considered going to Borderline Bar & Grill on Wednesday. "I just hope that since our community has been hurt, we can use the media attention that we're getting to actually talk about how our government has to step up and change."

"Everyone deals with their mourning in different ways, but I personally feel motivated to make a change," Klein, the Pepperdine senior, said. "I'm donating to places like Everytown for Gun Safety."

Kubly, the alum who was a friend of one of the victims, planned on going to college night with his girlfriend, but decided he should do work for his online master's program instead. He wants to focus solely on remembering the victims, not on gun laws.

"I think politicizing things like this or any type of shooting is disrespectful to the people who jumped in front of that gun to save those around them," Kubly said. "What's best is that we think about the people that sacrificed."

Kubly still lives near his alma mater and stays in touch with other alums and current Cal Lutheran students.

"There's going to be an outpouring of compassion and help [in the community]; the Cal Lutheran community is very strong," Kubly said. "It's unfortunate that it takes something like this to bring people together, but I know the students are going to rally together."

"Because [Pepperdine is] a Christian campus, prayer can be a part of what we do," Klein said. "Faith will be what gets us through this tragedy."

"I think everyone is just really shocked because we can all think about being [at Borderline Bar & Grill], and we know so many people who were there," Dennin said. "It happened in a community that's supposed to be safe."
