CHENEY - The Washington State Patrol is investigating allegations that the former manager of the State Crime Lab in Cheney mishandled case files and claimed to have completed laboratory case work that was not actually done.

So far, the investigation reveals that at least five cases had been mishandled. The manager resigned from state service during the investigation. According to the WSP, there is no evidence that the alleged misconduct led to any wrongful convictions.

The investigation began when those working for the manager raised concerns to the Crime Laboratory Division Commander. Information gathered to date does not implicate any other lab employees in 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," WSP Crime Laboratory Division Commander James Tarver said.

In addition to the original investigation conducted by the WSP Office of Professional Standards, Tarver ordered an internal management audit of the Cheney operation and requested that WSP Risk Management Division conduct a full evidence audit for the Cheney lab.

The cases involved in this investigation appear to be older ones, assigned to the manager while he worked as a front-line crime lab scientist, the WSP reported.
