John Thomas was 28 when he was shot dead on the evening of May 9, 2016, in Hayti, Missouri. Officers responding to 404 South 5th Street found Thomas with a gunshot wound to the back of his head after an argument with his on-and-off girlfriend, Lisa Hooper, reportedly sparked when Thomas learned Hooper had sent nude photographs of herself to another man.

The pair were in a vehicle when the dispute escalated. Witness Brandon Hamm, who was riding in the back seat, said he heard a loud noise and saw a flash; that account, investigators reported, matched physical evidence that did not support Hooper’s initial claim that the gun had accidentally discharged. Hooper was arrested and charged with first-degree murder and armed criminal action.

A Butler County jury found Lisa Hooper guilty on April 28, 2017, and she was jailed without bond. Did anyone in Hayti know John Thomas or witness the events that night and hasn’t yet come forward with information?
