I can speak to the national system, sir. We have not helped solve any crime where the offender was unknown. There has been a handful of cases where the offender/suspect was already known by the investigating body and we provided updated data, such as an updated photograph or address, which advanced the investigation. But we have not helped in any cases where the crime was unsolved and the offender was unknown.
