Duane H. Sutherland has resigned as chief of South Jordan's 8-member police force, a position he has held since 1978.

Mayor Theron B. Hutchings announced the resignation with an expression of appreciation for Sutherland's service to the city and its residents. However, the mayor offered no reason for the resignation, and other city officials declined to comment on the matter.Sutherland could not be reached for comment Tuesday. The resignation became effective May 3.

The City Council is scheduled to appoint an interim chief or department supervisor at its regular meeting Tuesday night. Police Sgt. Lindsay Shepherd is considered the leading candidate for the interim job.

Sutherland became the city's first police chief and the only officer when South Jordan established its own police department 13 years ago. Before that, he was a part-time police officer in Salt Lake City and a security foreman at Kennecott.
