Antonio Seville Thompson was 26 when he was found fatally shot inside an East Side Kansas City apartment on November 23, 2011, the eve of Thanksgiving. He was a father of two; his death was one of several homicides over that holiday weekend and left his family grieving and seeking answers.

Investigators have not publicly identified any suspects and no arrests have been announced. Few details about the circumstances leading to the shooting have been released, and the case grew cold as the family waited for resolution.

Antonio’s mother, Rosilyn Temple, channeled her grief into activism, founding KC Mothers in Charge to support other families bereaved by violence and to work toward reducing killings in Kansas City.

If anyone knew Antonio, was in that neighborhood on November 23, 2011, or has information about his death, please come forward to help the family find answers.
