Six crises. One missing piece.
Every system built to solve crime assumes the person with the answer already knows they have it. They don’t. The witness doesn’t know they’re a witness.
HOLMES is built for this.A family still waiting for answers — and an investigator who never closed the file.

The system isn’t just failing homicide victims. It’s failing survivors, the missing, trafficked children, and Indigenous communities — and the people who could help solve their cases.

About the National Center for Open & Unsolved Cases
The National Center for Open & Unsolved Cases partners with law enforcement and the community to give long-unsolved cases new visibility — and to connect the public to the cases they may be able to help solve. Behind every statistic are families still waiting for answers and the officers who never stopped working the case.
Crime costs the U.S. an estimated $5.7 trillion every year, leaving communities burdened by fear, lost lives, and unanswered questions. Solving cases is how we begin to take that back — one connection at a time.
