Why is my DUI charge not filed?

In Washington State, a lot of DUI cases are taking 6-15 months to file. This is especially true in blood draw cases. The Washington State Toxicology Lab has a huge backlog of blood draw cases. I believe the number is in the 1000’s.  Procedurely, the arresting officer sends the two blood vials to the Toxicology Lab for analysis. The Lab then has to send the blood results back to the police department that made the arrest, who then forwards it to the prosecutor’s office with the police report – for review and a decision on filing. Most cases will eventually be filed, however, this can be a frustrating wait for clients.
