ST. LOUIS – From hotels to casinos, FOX 2 News has reported how sex trafficking has hit the region hard. Now the fight against it has gone mobile, with eyes on the road everywhere.

Hundreds of buses are capturing video on the move, and it’s proven to solve crimes. Now, the drivers themselves are being trained on how to spot sex trafficking and help stop it.

“We’re not just running public transportation. Our company exists for the betterment of the region,” Kevin Scott, Metro’s executive vice president of public affairs and security, said.

Inside the Real Time Camera Center, public safety dispatchers monitor hundreds of cameras at stations and on buses.

Each bus has eight cameras inside and outside, which can help solve crimes that have nothing to do with the bus. The captured video can be utilized by outside police agencies.

“Through our law enforcement portal asking us, ‘Hey, on this date at this time did you have a bus that went through this area? We’re looking for a green vehicle,’” Scott said.

Metro has added a new tool—consulting with retired police Sgt. Adam Kavanaugh of Crisis Aid International, “…to really start addressing where we know things already happen.”

“When I’m driving down the street and I’m that bus operator, what can I look for that I might see on my route?” Kavanaugh said.

Kavanaugh was pleased to hear of a bus driver’s success helping a victim before he even began training.

“If they come across a victim who’s looking to get out that wants a way out, well, we’ve got the resources here,” he said. “We’ve got a 21-bedroom house up in Western Michigan to get them out of the area and get them someplace safe.”

With Crisis Aid’s five offices in the region and other locations around the country, it can intervene where there’s trouble. And a partnership with the transportation system broadens that reach.

“We think that’s paramount to helping support what is really a become a dynamic issue nationwide and also internationally,” Scott said.

Now, putting trained eyes over 400 square miles of bus routes and expanding scrutiny on a crime that often goes unnoticed.
