Tamera Mowry confirms niece Alaina Housley was killed in Thousand Oaks bar shooting

Tamera Mowry's niece has been killed in the shooting at Borderline Bar and Grill in Thousand Oaks, Calif.

The former "Sister, Sister" actress confirmed in a statement obtained by TMZ on Thursday afternoon that 18-year-old Alaina Housley, a freshman at Pepperdine University, was one of the victims in the Wednesday night shooting.

"Our hearts are broken. We just learned that our Alaina was one of the victims of last night's shooting at Borderline Bar in Thousand Oaks," she said. "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."

Mowry's confirmation of the devastating news comes hours after she revealed in an exchange with Housley's roommate on Twitter that her niece was missing and feared that she was one of the 12 victims of the tragedy.

The L.A. Times had reported that Housley's Apple Watch and iPhone showed that she was still inside the bar on the dance floor, where she had gone out line dancing with some friends on Wednesday night.

"My gut is saying she's inside the bar, dead," Adam Housley, who is married to Mowry, said. "I'm hoping I'm wrong."

"The Real" co-host Tamera Mowry-Housley married Adam Housley in 2011. He's a former correspondent for Fox News.

The attack was the most deadly mass shooting in the U.S. since February 14, 2018, when 17 students and teachers were shot dead at Marjory Stoneman Douglas High School.

Veteran of the US Marine Corps, David Long, 28, was identified as the shooter on Thursday morning. He's believed to have used a Glock .45-caliber handgun.

Long was also found dead at the bar from a gunshot wound, although it remains unclear if the wound was self-inflicted or if the shooter was gunned down by police.
