Idaho law enforcement agencies are continuing to work through a backlog of untested rape kits in the wake of a law requiring that all rape kits undergo testing, a process that could take a while.

According to a report from the Twin Falls Police Department published last week, it sent 18 new sexual assault kits for testing last year.

The Times-News reported Monday that testing for 10 of those kits was completed and eight are currently undergoing testing.

Twin Falls police are also preparing to send 41 previously unsubmitted kits to the FBI for testing.

A 2016 audit found hundreds of kits that agencies statewide had never sent to Idaho State Police Forensic Services for analysis.

The FBI offered to help and is accepting older kits from cities across the state.
