The Milwaukee County medical examiner’s office has revised its ruling on the death of Derek Williams, who died in Milwaukee police custody in July 2011, from natural to homicide, according to the district attorney’s office.
The decision came after the Journal Sentinel alerted an assistant medical examiner to newly released records – including a video of a suffocating Williams pleading for help from the back of a squad car – and also made him aware of a national expert who said Williams, 22, did not die naturally of sickle cell crisis.
