On 6/27/2023 deputies were dispatched to a report of a vehicle prowl in the area of Chatter Creek trail head outside Leavenworth. The victim reported someone had broken her passenger side window and stole her wallet along with other items. The victim’s debit card was later used at a business in Leavenworth. Deputies followed up with that business and were able to obtain a vehicle description of the person who used the stolen debit card.
On 8/5/2023 the Chelan County Sheriff’s Office Forrest Service Deputy learned of additional vehicle prowls along the Highway 20 corridor on National Parks Service land in the northwest area of Chelan County. Through the deputy’s investigation, he was able to identify a vehicle in the area of the prowls as the same one involved in the Chatter Creek car prowl. This time they were able to obtain the license plate number of the vehicle.
More follow up from the deputy led him to evidence that the registered owner of the suspect vehicle was facilitating the sale of some of the items stolen from the vehicles. At that point the case was turned over to Chelan County Sheriff’s Office detective unit. They were able to identify the male and female seen on surveillance cameras as Sierra L Cotter and Brandon R. Sutherland of Everett.
Detectives later arrested Cotter in King County and booked her in the Chelan County Regional Justice center on charges of Possession of Stolen Property, Identity Theft, and Forgery. They also obtained a search warrant for two storage units in the Everett area that belonged to Sutherland and Cotter.
Chelan County Sheriff’s Office detectives served the search warrants in Everett with the assistance of Snohomish County Sheriff’s Office. As a result of this investigation, 2 Chelan County cases, 2 National Parks cases, and 10 Snohomish County cases were solved. Suspects may now be facing charges in Snohomish County as well.
This case is another example of the Chelan County Sheriff’s Office commitment to protecting our citizens from people that come from other areas to commit crimes. We are committed to go beyond county lines to investigate and apprehend those suspects.
