Modern cars with GPS trackers installed can help police locate and retrieve stolen cars, but the Michigan State Police were in for a surprise when a GPS tracker led them to a semi-truck towing a car hauler carrying several stolen cars - including patrol cars.

According to The Detroit News, officers responded to a 911 call from an owner reporting their car being stolen. The car had a GPS tracker installed, allowing police to track the location. Using the GPS coordinates, police discovered the car was travelling on a freeway near Van Buren Township and prepared to pull the car over.

When officers caught up with the car, they realized it wasn't being driven on its own power. Instead, it was being hauled on a transporter trailer hitched up to a Peterbilt truck, along with several other stolen cars.

"The vehicle was initially believed to be traveling under its own power on the freeway, in Van Buren Township", the Michigan State Police said. "However, troopers saw a semi-tractor with a car-hauling trailer. On the trailer was the stolen vehicle's registration plate and a traffic stop was made."

Once the truck was stopped, officers discovered at least three other cars that were reported stolen by police departments loaded on the truck including a 2020 Dodge Charger stolen from the Warren Police Department.

There was also a 2018 Dodge Charger stolen from the Southfield Police Department, and a 2017 Dodge Charger that was taken from the Detroit Police Department. Photos also show a Dodge Durango and a Jeep Grand Cherokee being carried on the trailer. $10,000 in cash was also recovered from the truck's cab.

The truck driver protested their innocence, telling troopers he recently bought the semi-trailer and was driving to Belleville to pick up another vehicle. The Michigan State Police's Southeast Auto Theft Team is still investigating the incident.
