DETROIT (AP) — About 600 rape kits that remained from more than 11,000 found in a Detroit police property storage facility in 2009 are finally being processed.

The Detroit News reports that the Wayne County prosecutor's office has sent the final batch of kits to labs for testing. State police will review the results.

Prosecutor Kym Worthy has pushed efforts to test the kits and prosecute old cases. Her office says that so far, 130 people have been convicted and 818 serial sex offenders have been identified since authorities started investigating earlier batches of the kits.

The kits contain DNA and other evidence from rape cases, but a majority of the 11,000 kits were never tested in a lab. Worthy notes that testing of the kits is "a very long process."
