Court records indicate that Joseph Jackson had abused his wife for a long time before murdering her. Her efforts to flee that abuse were unsuccessful. Jackson followed her and shot her to death in the home where she worked and then told her employer and friends that his wife was ill and had to leave.
The murder took place at Oak Lodge, Choctaw Nation, on March 9, 1885. The Jacksons were Black.
His trial began on September 7, 1885. He was convicted a week later, and sentenced to death. His suicide attempt soon before his execution failed.
Joseph Jackson was hanged on April 23, 1886.
