A Texas teenager caught the bus for school on December 15 and shortly thereafter turned off location sharing on her phone.

Kiersten McWilliams hasn’t been seen since, and her mother fears she could be in grave danger.

“She’s really sweet, she’s athletic, she’s really smart,” Rayna Glass told KHOU. “She’s pretty, you wouldn’t miss her in a crowd.”

McWilliams missed Christmas, New Year’s, and her 16th birthday, Glass said.

Rosenberg Police said they were looking for a man believed to be her boyfriend — Jacob Warren — and said they believe the teen is with him.

Glass said that her daughter has no car, no money, no identification, no Social Security card.

“You can come home,” she said, addressing McWilliams. “You know that. So just come home and we’ll figure all this out. You know we will because we do it all the time.”

The Fort Bend County Sheriff’s Office said it considers McWilliams a runaway but wouldn’t provide details because of privacy and safety. Glass, however, says her daughter never left home before.
