Missouri law enforcement investigators were able to find a kidnapped 12-year-old girl this weekend after discovering a fake Facebook profile that the girl had set up.

The girl’s mother saw her in their home’s front yard around 3:45 p.m. on Friday, and when she woke up from a nap around 5:45 p.m., her daughter was gone. A big search in the Miller, Missouri, area began on Friday night, and the local sheriff’s department contacted the FBI and Missouri Highway Patrol to help track her down. Those agencies then discovered a fake Facebook profile that the girl used — including to befriend the man that allegedly kidnapped her.

Investigators also found phone calls and text messages that the girl exchanged with a number in St. Louis, including messages promising that she would “make a run for it” and would “wait by the barn” outside her house. They tracked the cell phone to Kevin Nosser, a 47-year-old living in St. Louis, and arrested him, recovering the girl safely. Nosser is being held on $1 million bond.

Thankfully police were able to quickly identify the girl’s fake profile and use it to track her alleged kidnapper. While parents might feel like snoops monitoring their children on Facebook, cases like this show it’s a good idea to at least get a picture of what your children are doing online.
