What Testing Backlogged Sexual Assault Kits is Teaching Law Enforcement About the Crime

The effort to address a backlog of sexual assault kits nationwide has led to tens of thousands of long-shelved kits being tested over the last several years. The FBI Laboratory alone tested more than 3,600 kits in a four-year effort to assist state and local agencies.
The work being done to inventory and test the evidence kits is one part of the story. The other part is what has been discovered about the serial nature of many sexual offenders as thousands of cases are added into the FBI’s national DNA and violent crime databases.
