Michael Vaughns, a 55-year-old African American supervisor with Houston’s solid waste management department, was fatally shot at his southeast Houston workplace on December 21, 2015. The shooter was a subordinate, Tyrone Roy Auzenne, who brought a semi-automatic pistol to the office and shot Vaughns in his office. Auzenne was taken into custody at the scene and charged with murder.

Court testimony described long-simmering jealousy and resentment by Auzenne toward Vaughns; family members said the motive appeared tied to workplace jealousy because Auzenne had previously filled Vaughns’ position temporarily and resented Vaughns being recruited from Dallas. Vaughns’ family characterized him as a respectful, dedicated worker and a loving family man whose death profoundly affected relatives and colleagues.
