Law enforcement officials in Waller County, Texas, say the cause of Sandra Bland’s death in police custody was suicide. Bland was initially stopped for allegedly failing to signal a lane change. Dash cam footage shows Texas State Trooper Brian Encinia forcibly removed her from her car and threatened to “light [her] up” after she failed to put out her cigarette. On Thursday, Assistant Prosecutor Warren Diepraam said preliminary autopsy results show Bland hanged herself in jail.

Warren Diepraam, assistant prosecutor: “The only injury which was present on her neck or head was what’s called a ligature thorough or a ligature mark. This is consistent with a suicide, according to the Harris County Institute of Forensic Science, because the mark on her neck, which I will show pictures of at the completion of this discussion, is a uniform and consistent mark around the neck of Miss Bland. Had this been a violent struggle or a murder, you would most likely not expect to see a consistent and uniform ligature mark around her neck.”

Sandra Bland’s family has questioned the official account, saying they don’t believe she committed suicide. We’ll speak with Sandra Bland’s sister, Sharon Cooper, and the family’s attorney after headlines.
