Tamera Mowry and husband Adam Housley are mourning the loss of their 18-year-old niece on Nov. 8, after learning she was among the 12 people killed when a gunman opened fire at the Borderline bar in Thousand Oaks, CA. Following hours of searching for the teen, they shared the tragic news.

“Our hearts are broken,” began the statement obtained by Us Weekly. “We just learned that our niece Alaina was one of the victims of last night’s shooting at Borderline bar in Thousand Oaks. Alaina was an incredible young woman with so much life ahead of her and we are devastated that her life was cut short in this manner. We thank everyone for your prayers and ask for privacy at this time.”

Tamera had been desperately searching for Alaina in the hours leading up to the tragic news. She reached out to Alaina’s roommate on Twitter, saying, “Ashley this is her aunt Tamera Mowry Housley. Can you please DM me your information?” after Ashley posted photos of Alaina and described her as “wearing denim shorts, a blue flannel, and sneakers.” Tamera later replied again, writing, “We haven’t found her yet. It’s been 7 hrs since the shooting.”

Tamera’s twin sister Tia was also aching to find the young woman, posting a photo with her at Tamera’s wedding and writing, “Alaina Housely we are praying. We love u! If you know anything or any information please let us know. We love you! #borderline.”

Though Adam continued to ask friends and fans to help find Alaina, he admitted to the Los Angeles Times that he feared the worst. “My gut is saying she’s inside the bar, dead,” he said, explaining that her phone and Apple watch location still showed her there. “I’m hoping I’m wrong.”

Our hearts go out to the Mowry-Housley family in this tragic time.
