‘Staircase’ documentary prosecutor died of natural causes

DURHAM, N.C. — An autopsy says natural causes claimed the life of a North Carolina prosecutor found dead at home last year amid attention over “The Staircase” documentary series.

Freda Black helped prosecute the 2001 killing examined by the documentary. An autopsy released Monday by the state medical examiner cited liver disease due to alcoholism as the cause of death.

Police have said Black was found dead last July and the 57-year-old’s death didn’t appear suspicious.

Black gave closing arguments at the 2003 trial that ended with novelist Michael Peterson convicted of murdering his wife. A judge later ordered a new trial, and Peterson entered a special plea in 2017 acknowledging that prosecutors had enough evidence to convict him of manslaughter.
