How long should closed evidence in adult sexual assault investigations be retained?

The retention period of closed evidence in adult sexual assault investigations is crucial for several reasons, including the potential for new evidence or advancements in forensic technologies that could help solve the case, the need for potential retrials, and the rights of the victims involved.

Choosing a five-year retention period aligns with many jurisdictions' guidelines, which often emphasize the importance of keeping such sensitive materials accessible for a reasonable amount of time post-investigation. This duration balances the need for law enforcement to have sufficient time to review and utilize evidence while also reflecting an awareness of the evolving nature of sexual assault cases, where new information can surface long after an initial investigation has concluded.

This choice supports the principle of ensuring justice and accommodating the needs of victims, who may come forward later, or where legal and scientific developments may make it necessary to revisit previously closed cases. In contrast, shorter retention times could impede justice for victims or prevent law enforcement from effectively managing all aspects of the investigation. Retaining closed evidence for five years allows for effective case management and supports the overarching goal of ensuring justice is served appropriately and fairly.
