The Cook County Sheriff's Office says it has found dozens of unprocessed sexual assault kits in the evidence room at the Robbins Police Department in south suburban Chicago.
Cook County Sheriff Tom Dart's office said 51 kits, dated from 1986 to 2011, were never submitted for analysis.
Authorities said they're working to have the kits submitted.
Dart plans a Tuesday evening town hall meeting with Robbins Mayor Irene Brodie. Dart's office says in a statement that he and the mayor will host the meeting to talk about the future of the village and "what is being done to make it a safer and stronger community.''
A call to Mayor Brodie seeking comment wasn't immediately returned.
Illinois in 2010 became the first state in the union to mandate that all rape kits be sent to a lab within 10 days.
