Evidence preservation.

This Wyoming bill requires law enforcement to preserve biological evidence from sexual assault cases for up to 50 years or until all applicable legal deadlines pass, whichever comes first. It also mandates that evidence from violent crime convictions be kept for five years or until the convicted person's release, whichever is longer, with a 180-day notice period before disposal allowing incarcerated individuals to request DNA testing. The law directly affects law enforcement agencies (who must implement preservation), convicted individuals (who may seek DNA testing), and sexual assault victims (whose evidence remains available). Key provisions include requiring agencies to save representative portions of evidence for future DNA analysis before disposal and ensuring compatibility with state DNA databases. The bill does not change current practices for non-sexual assault evidence.
