Police said the witness took the car’s license plate number and reported them to the police department. Officers then ran the plates and found Adam Michael Lee, 36, and Windy Lund, 32, at the address to which the car was registered to.

According to police, detectives were looking at a check fraud case and found that a large check had been stolen from the mail.

Both Lee and Lund were arrested for alleged “identity theft, possessing stolen property and burglar’s tools in connection with the items the probation officers found in their home.”
