OMAHA, Neb. (AP) — The city of Omaha and Douglas County will share some crime lab services under a new agreement.

The Omaha City Council voted unanimously Tuesday to approve an agreement supported by Mayor Jean Stothert. It has already been approved by the Douglas County Board and will go into effect on Jan. 1.

The agreement means the Douglas County Sheriff’s Office will analyze drug samples, blood-alcohol tests and crime-scene evidence for itself and the Omaha Police Department. Police will handle ballistics tests for both agencies.

The sheriff’s office will hire two new chemists. A sheriff’s deputy will be assigned to the police department’s electronics unit, and crime-scene technicians from one agency can respond to calls from the other agency.
