A 16-year-old girl is believed to have left home with someone she met on the KIK messaging app, and may be traveling out of state.

According to WDIV Detroit, Michigan State Police have issued an Endangered Missing Advisory for 16-year-old Joy Dene Martin of Saugatuck, Michigan, after the teen left home with bags of clothing. According to CBS Detroit, she was seen leaving Saugatuck with someone she met on the messaging app, which does not require users to register their phone numbers, providing a high level of anonymity.
