Diamond Stephens was a 39-year-old Black transgender woman found dead in Meridian, Mississippi, on the evening of June 18, 2018. Her van had crashed into a house, but the crash was not the cause of death; Stephens had suffered a fatal gunshot wound to the back of the head. Family members said she had been on her way home to prepare for work.

Initial reports and statements from officials misgendered Stephens and used her former name, which delayed wider awareness of her killing and complicated early calls for justice and support from LGBTQ+ advocates. Meridian Police opened a homicide investigation and said she likely was not alone in the vehicle when she was shot, with investigators believing one or two other people may have been present.

No arrests, named suspects, or persons of interest have been announced, and the case has grown cold. If anyone knew Diamond, was in Meridian that night, or has information about who was with her, please come forward.
