In Washington and most states, the Prosecuting Attorney or District Attorney actually "press charges." What this means is once 911 is called, or a police report is filed, the PA or DA's office determines if they want to pursue criminal charges. The PA or DA in the county or jurisdiction where the crime occurred would be the entity pressing the charges. In this case, you may want to contact the PA or DA where the crime occurred and ask them about the status of the case. The statute of limitations for the PA or DA's office on a case like this is usually 2-3 years so there would likely be more time for them to press charges.
