KNOXVILLE, Tenn. -  Three people are behind bars tonight, charged with locking their children in a trailer filled with furniture on their move to Fort Myers. Those children weren't the only ones.

Authorities near Knoxville, Tenessee pulled over a U-haul truck after somebody called 911, saying they'd seen two children beaten and thrown into the back outside a Walmart.

Inside that truck, they actually found seven people locked up with the furniture. That includes four men, two children under ten and the children's grandmother.

Three people were arrested, including 30-year-old parents Joshua and Mary Jackson. They were allegedly riding in a car behind the truck. They're now charged with child endangerment.

The truck's driver, 25-year-old Rocky Ewing, is charged with seven counts of reckless driving. That's one count for each person in the back of the truck. 

Everybody involved is believed to be related. Authorities say they were moving from Steubenville, Ohio to Fort Myers.

The kids are fine and were released into the custody of their grandmother, who was riding in the back with them.

We're told the truck had to be towed because the only person with a valid license was the grandmother, and she didn't want to drive it.
