CHENEY, Wash. -

The Washington State Patrol is investigating allegations that the former manager of the State Crime Lab mishandled case files.

According to the State Patrol the manager claimed to have completed laboratory case work, but it was not actually done.

During the investigation, troopers discovered at least five cases were mishandled. The manager resigned from state service during course of the investigation. 

Troopers said the investigation started when people working for the manager raised concerns to WSP Crime Laboratory Division Commander James Tarver. Troopers do not believe other employees committed similar misconduct.

“We continue to have confidence in the work of our front-line scientists and supervisors in Cheney, and at our other labs throughout the state,” said Tarver in a press release. “These allegations involved a single laboratory manager, and do not appear to reflect upon any of our other personnel.” 

The state patrol is notifying local prosecutors and the police agencies which submitted the cases identified in the investigation.

The cases involved in the investigation are older ones that were assigned to the manager as he worked as a front-line crime lab scientist.
