Sister, Sister star Tamera Mowry-Housley and her husband confirmed Thursday afternoon that their 22-year-old niece Alaina Housley was killed in the Borderline bar shooting. “Our hearts are broken,” a statement from the couple reads. “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.” Earlier in the day, Mowry-Housley had been frantically searching on Twitter for information about her niece, a Pepperdine freshman who was at the Borderline Bar & Grill last night when a gunman opened fire. Twelve victims were killed in the shooting, and multiple people were injured. Mowry-Housley first responded to a tweet by her niece’s suitemate, who was searching for Alaina. According to other tweets by the suitemate, several girls from Alaina’s residence hall went to Borderline Wednesday evening to line dance. Mowry-Housley is married to former Fox News correspondent Adam Housley.
