During a press conference Monday, a Florida state attorney says he hoped Kraft's alleged involvement would bring attention to what he called "modern day slavery."
Advocates in Philadelphia say sex trafficking is more widespread than most people realize, and the Florida case should serve as an example.
Those who traffic humans, whether for sex or labor, are in the business of making money because, like any market, there is a demand, says Shea Rhodes.
"In order to eliminate trafficking and sexual exploitation, we must focus not only on the traffickers, but also on that piece of the market that drives it, which is the sex buyers," Rhodes said.
Rhodes is the director and co-founder of Villanova University Law Institute to Address Commercial Sexual Exploitation. She says some traffickers move people around the country; others are brought here from foreign lands with the promise of a better life, only to be bought and sold and traded among abusers.
"They are often sleeping inside that location, cooking inside that location, or close by. They don't have a lot of clothing, they don't have any money on their person, they aren't free to speak to people," Rhodes said.
Often, they don't speak English, have no identification, money or documents.
Rhodes works to help victims and tighten laws on human trafficking.
She says anyone who suspects human trafficking should immediately call the National Human Trafficking Hotline at 1-888-373-7888.
