NASHVILLE, TN (WSMV) - Large events like the NFL Draft present massive opportunities for Nashville but could also present massive dangers for you family.

Events are always appealing to traffickers, according to End Slavery Tennessee, because it’s a money-making opportunity. Police said anywhere a large group of men gathers is an opportunity.

“Traffickers are savvy,” End Slavery Tennessee CEO Derri Smith said. “This is a money-making business and they use the tools at hand to find their victims.”

The tool in this case is Snapchat.
