"We want you home. No matter what, we just want you home," said Kim Alongi in an interview with The Star-Ledger.

Kara Alongi, 16, disappeared Sunday evening after posting the message, "There is somone in my hour ecall (sic) 911" on Twitter

People re-tweeted the message and created the hashtag "#helpfindkara," but police now say the tweet was a hoax and the teen called a cab. She was then seen on surveillance video at a nearby Rahway train station, wearing a thick backpack and purse. The Star-Ledger reports that police are now investigating her disappearance as a juvenile runaway case.

Kim Alongi told the paper that the last time she saw her daughter she told her mother that she didn't want to go to her brother's hockey game because had a headache and wanted to lay down.

"This was totally out of character," Kim Alongi told the paper. "We had no idea any problems were existent at school ... nothing at home. So it's a total shock."

The paper reports that authorities do not believe Kara is in danger, although she reportedly has celiac disease, a condition which makes it difficult for the body to process gluten.

"Regardless of what happened, she's still a missing 16-year-old girl who's alone as far as we know," Kim Alongi said to the Star-Ledger.
