Edmond Police are looking for whoever broke into at least 9 vehicles at 4 parks on Saturday afternoon.
The thieves smashed the windows of cars parked at Pelican Bay, Hafer Park, Stephenson Park, and the dog park off 33rd and Blvd.
Investigators believe all the break-ins were done by the same group of people.
"They've got a system down, it's quick, punch the window in get what they can see in the front and leave," says Jennifer Monroe with the Edmond Police Department.
The thieves made off with items like purses, a laptop and an I-pad.
The parks were pretty crowded on Saturday, but so far, police do not have a suspect or vehicle description
