When Kevin Kimmel parked at a truck stop in New Kent County, Virginia, he probably didn’t expect that he would save somebody’s life.

However, as Kimmel was sitting in his rig, he noticed a suspicious looking RV with black drapes. Then, he saw a distraught young girl’s face take a glimpse out of the RV window.

A few moments later a man knocked on the RV door and went into a Pilot Gas Station nearby. After the man exited the station, he headed right back to the RV. Kimmel told Richmond CBS affiliate WTVR:

“I saw a guy come up and knock on the door then go inside the Pilot–then quickly came back and knocked again, all of the sudden the thing was rocking and rolling.”

Kimmel, a veteran trucker, said it was a no brainer what was going on, so he dialed deputies.

When the authorities arrived, they arrested a couple who had been forcing a 2o-year-old girl into sex slavery. The girl was malnourished and tortured by her captors.

The affidavit reported the girl’s feet being punctured, nails being hammered into her, and that she even sustained severe burns from having a hot key pressed into her flesh. The key was how the traffickers branded the girl.

Kimmel, who is a father and grandfather said of his actions, “I’m just happy I helped her.”

As human trafficking is the fastest growing criminal industry in the world, it’s important that we all remain vigilant when we see something out of the ordinary like Kimmel did.

Who knows, you may just save someone’s life.
