People reported that Mowry-Housley replied to a tweet early Thursday in which a girl said her suitemate was missing.
“This is her aunt Tamera Mowry Housley. Can you please DM me your information?”
The girl replied that she had been in contact with Mowry-Housley’s husband, to which “The Real” co-host replied, “Ok. Thank you. Is she the only one unaccounted for?”
"Yes, all the other girls are safe," the suitemate replied.

The couple’s niece, Housley said, is 18-year-old Alaina Housley, who was at the bar with friends.
The Los Angeles Times reported that Housley arrived at Los Robles Regional Medical Center to look for his niece, but a guard didn't allow him in as the facility was on lockdown.
Housley said his niece’s Apple Watch and iPhone showed her location as the dance floor of the bar.
“My gut is saying she’s inside the bar, dead,” he said. “I’m hoping I’m wrong.”
Housley said two of his niece’s friends lost her in the fray.
On Twitter, Housley asked for prayers and said he is staying positive.
"Please pray if you believe....pray," he said, later tweeting, "Staying positive and praying and hoping and wishing there was more I could do."
Mowry-Housley's twin sister, actress Tia Mowry, also tweeted asking for prayers.
“Woke up shocked. Please pray. Please pray. I am numb.”
Housley told LA Times he called the hotline and went to the crime scene, but wasn't told much.
"We haven't found her yet," Mowry-Housley tweeted at 5:52 a.m. Pacific time. "It's been 7 hrs since the shooting."
