The attorney general’s office says there are over 6,400 sexual assault kits that have not yet been submitted for lab testing by law enforcement agencies in Washington state.

The attorney general’s office has completed an inventory of the untested kits and is developing a plan to conduct testing.

The state was awarded a $3 million federal grant last year to fund the testing and investigation of kits, which have been stored at police departments across the state and contain forensic evidence collected from victims.

The state will use $1.5 million of the grant to fund testing, the maximum amount allowed.
