The Whitman County Prosecutor’s Office will not seek charges against WSU Police Officer Dillon Tiedeman-Mueller after determining he acted lawfully and in good faith, according to WSU Police.

Tiedeman-Mueller was involved in an officer-involved shooting at Global Scholars Hall in March 2024. Following the shooting, he was placed on administrative leave, in accordance with protocol, while Washington State Patrol began their independent investigation into the incident.

WSP concluded their investigation in November 2024. Their findings were subsequently submitted to the Whitman County Prosecutor’s Office for review.

Leading up to the shooting, officers were responding to reports of an armed suspect in Global Scholars. Upon arrival, officers determined 20-year-old John Bazan was armed with a knife and attempted an unsuccessful taser deployment. It was at this time Tiedeman-Mueller fired his gun, missing Bazan.

After a subsequent successful taser deployment, officers were able to take Bazan into custody. Bazan was then taken to Pullman Regional Hospital for evaluation.

After being released from the hospital, Bazan was initially charged with assault, resisting arrest, intimidation of a public servant and obstruction. It was later determined that initial reports came from a caller found to be Bazan himself.

The decision not to seek charges against Tiedeman-Mueller marks an end to the incident with the prosecutor’s office choosing not to seek any charges from incident.

In April 2024, Prosecutor Denis Tracy announced his office would not be seeking charges against Bazan, citing a mental health crisis.

“I decline to charge him because this is all due to his mental illness, which is now being dealt with at an in-patient treatment facility,” Tracy said, according to Pullman Radio. “In my judgment, it’s best for the community to not interrupt his mental treatment with a criminal case.”
