Investigation into destroyed DNA samples uncovers more problems with Seattle police evidence storage By Sara Jean Green, The Seattle Times Published: December 23, 2020, 10:12am Share: SEATTLE — Plagued by a chronically full evidence warehouse that led to failed fire inspections, the Seattle Police Department wrongly destroyed more than 100 post-conviction DNA samples in 2018 as part of an effort to make space for incoming items of evidence, according to a recently released report detailing an audit by the Seattle Office of Inspector General (OIG). Around the same time the DNA samples were destroyed, evidence from an unknown number of homicide investigations was also purged, according to the 19-page report.
