Last fall a Washington Department of Fish and wildlife officer took my rifle into evidence in a case involving unintentional shooting of an elk not meeting the requirements of a legal game animal. The officer gave me an evidence receipt, but I was not charged with anything. He told me that the prosecutor would review the evidence, his report, and my statement as well as witnesses and contact me to let me know if charges would be prferred. That was five months ago. How long can they hold my property without preferring charges?
