Over 1,000 kits still need to be tested after 11,000 were found in a Detroit warehouse.

Erykah Badu has announced her upcoming concert at Detroit’s Chene Park Amphitheatre will raise money towards processing over 1,000 rape kits that have remained unchecked since last decade, Pitchfork reports.

The kits are part of a cache of 11,000 found in a Detroit warehouse in 2009. Though the 10,000 processed so far have resulted in 2,616 DNA matches and the identification of 753 potential serial rapists, each one costs $490 to process.

As The Detroit Free Press points out, Badu has partnered with The Right Productions and their organization the African American 490 Challenge to raise the rest of the money.

The 490 Challenge will receive $5 from every ticket sold, as well as all the proceeds from a special $100-per-person pre-show reception and $1000-per-person VIP after-show reception.

“This is a huge day for Enough SAID/AA490. Everyone knows that Erykah Badu is a major, major talent in the music and song-writing industry,” said Wayne County Prosecutor Kym L. Worthy. “For her to lend her name, talent and time to this work is nothing short of a miracle. Justice for these forgotten sexual assault victims has been given a phenomenal assist.”

From the 10,000 processed so far, the Wayne County Prosecutor’s Office has obtained 36 convictions and DNA from the kits tested has been linked to crimes committed in 40 states and Washington DC.

The concert will be held August 12 with Hiatus Kaiyote opening. Read more about the history of the kits here.
