Tamera Mowry-Housley and her husband, Adam Housley, are desperately searching for their niece, Alaina Housley, who is seemingly missing after last night's deadly Thousand Oaks, California mass shooting at a local bar and music venue's "College Country Night."

The shooting at Borderline Bar & Grill left at least 12 dead and many more wounded, while suspect Ian David Long was also found dead inside the building after an apparent suicide. One of the attendees tragically killed was Ventura County Sheriff's Sergeant Ron Helus, who was responding to the incident.

Early Thursday morning, Housley's apparent suite mate, Ashley, tweeted that the young woman was missing along with the hashtag #Borderline, referring to the bar and music venue where shooting occurred.

The Real host responded publicly to the young woman's tweet, identifying herself as Alaina's aunt and asking her to send a private message so they could communicate.

The young woman who reported Housley missing online confirmed she's been in touch with "Adam," referring to Mowry-Housley's husband. Adam Housley also tweeted early Thursday morning asking his followers to pray. The couple have both been responding to fans throughout the morning, reporting there has not been any word from their niece.

Based on Ashley's tweets to Mowry-Housley, the actress's niece was allegedly with a group of young women who went line dancing at at the Southern California venue Wednesday night. The young woman is reportedly the only person not accounted for from that group, which caused the concern.

As of publishing, there are no further updates on the whereabouts of Mowry-Housley's niece. This story is developing...
