Matthew Bruce Williams, driving his red tow truck, pulled vehicle after vehicle to Metro Metals in May and June. All were sold for a few hundred dollars for scrap.
All also had been stolen, authorities said.
They were among more than 50 cars that had been stolen in St. Paul and sold for scrap in the past several months, often crushed just hours after they were whisked off city streets, private parking lots and driveways.
Ramsey County Attorney John Choi's office charged 10 suspects Wednesday in the "brazen" thefts that occurred between January and late June.
"Clean up your act," Choi warned auto thieves. "We are watching, and we will take aggressive actions against those stealing cars in our community."
Authorities said their three-month investigation showed that the suspects used three schemes:
• Thieves scouted out vehicles, then called tow truck drivers and lied about owning the vehicles. They sold the vehicles to the truck drivers, who sold them for scrap.
• Tow truck drivers stole vehicles from streets and parking lots and sold them for scrap.
