The niece of actress Tamera Mowry and husband Adam Housley is unaccounted for after she was last seen at the Borderline Bar and Grill in Thousand Oaks, California, where at least 12 people were shot and killed Wednesday night. Us Weekly reports that a Pepperdine University student named Ashley tweeted early Thursday about the Sister, Sister star's niece, "My suitemate is still missing; she is wearing denim shorts, a blue flannel and sneakers. Please let me know if you know anything." Mowry tweeted back, "Ashley, this is her aunt Tamera Mowry Housley. Can you please DM me your information?" Ashley then informed Mowry that she'd "been in contact" with Housley, a former FOX News correspondent, and that "there's nothing new to report at the moment." A few hours later, Mowry tweeted, "We haven’t found her yet. It’s been seven hours since the shooting." Meanwhile, Housley has tweeted, "Staying positive and praying and hoping and wishing there was more I could do."
