Police say Ki-Shawn Crumity, 26, met girl through Snapchat, and charged him with human trafficking and sexual assault

A 13-year-old Louisiana girl who went missing after meeting a man online was found alive in a box at his home several states away in Pennsylvania – along with evidence that she had been sexually assaulted, according to authorities.

Ki-Shawn Crumity, 26, faces charges of human trafficking, sexual assault, unlawful contact with a minor and corruption of a child after police in Pittsburgh said they arrested him on Thursday. He is one of at least three men who had been arrested as of Saturday amid an investigation involving law enforcement agencies in multiple states.

“This child … was groomed, exploited and then sexually abused by strangers who found her online,” Louisiana’s attorney general, Liz Murrill, said in a statement on Friday. “This is just one example of the dangers of social media and of human trafficking.”

Officials reported that the teenager at the center of the case disappeared from Louisiana the previous week after meeting Crumity through social media. Investigators said they tracked her across several states – and by Thursday, after receiving information from federal agents, Pittsburgh police discovered the girl trapped in a sheet-covered box in Crumity’s basement in the city’s Brighton Park neighborhood.
