An autopsy submitted a day after Sandra Bland was found dead in a Texas jail cell on July 13 ruled her death a suicide. The report, released to the public on Friday, disclosed in detail how she died.

Ms. Bland, 28, tied a white trash bag into a knot before using it as a ligature on her neck, the report showed. The autopsy also showed that Ms. Bland had 25 to 30 horizontal wounds, defined as “scarred regions of healing,” on her left forearm. She also had a “scabbed healing abrasion” on her left wrist and multiple abrasions on the right side of her back.
