Reflecting the in-custody deaths this week of two young black women, Sandra Bland and Kindra Chapman, and the seemingly endless torrent of police violence against black people, Twitter users launched the heartbreaking hashtag #IfIDieInPoliceCustody on Thursday night.

Sandra Bland, 28, was moving from the Chicago suburb of Naperville to Houston, Texas for a new job when she was stopped by Waller County police for failing to signal. She was arrested and charged with assaulting a police officer. Monday morning, she died in her jail cell. Authorities have called it suicide by hanging, but her friends and family believe she was killed.

In Alabama, Kindra Chapman, 18, was arrested for allegedly stealing a cell phone. An hour after she was booked on Tuesday, she was also found dead in her cell, and authorities again attributed it to suicide by hanging, AL.com reports.
