MADISON - Less than 5 percent of Wisconsin’s backlog of untested rape kits has been cleared since the state received $4 million in grants two years ago, figures released Wednesday by state authorities show.

As of Sept. 22, results from testing 176 kits were available to law enforcement agencies, which hope the evidence will help identify serial rapists or others who eluded justice over more than two decades.

It is unknown whether any of the results so far have helped investigators solve crimes. State Department of Justice officials plan to release aggregate testing results as they become available.

State authorities have more than 6,300 rape kits that were kept in local police storage rooms or hospitals and never sent to state crime labs. More than 4,000 of the kits — including more than 1,000 involving possible child victims — are now scheduled for testing.

The testing effort, beset with a series of delays, is funded by grants from federal authorities and New York prosecutors, money awarded in September 2015 after a USA TODAY investigation identified at least 70,000 untested rape kits nationwide.

TIMELINE: Delays in testing rape kits

State Department of Justice officials released the new tally of tested evidence while launching a website with responses to common questions and interactive graphics. The graphics mostly contain information previously reported by USA TODAY NETWORK-Wisconsin with two exceptions.

First, the graphics reveal how long untested rape kits were stored. Law enforcement agencies and hospitals reported receiving most in the past decade and some as recently as 2015. The oldest kit with a known date was received in 1991.

The graphics also show by county of origin why rape kits weren’t submitted to crime labs years ago and how many kits are now scheduled for testing. This type of information has only previously been released at the statewide level.
