Santos R. Jackson, 37, was found dead inside a residence on North 9th Street in St. Joseph, Missouri, in August 2021. Responding officers encountered blood and cleaning agents at the scene and obtained a search warrant; inside they discovered Jackson’s body. Investigators determined he had sustained a single gunshot wound to the back of his head.

Police identified 24-year-old Tucker James Autenrieth as a resident of the house. Autenrieth told officers Jackson had arrived armed with a .45 pistol and an altercation followed. He said he struck Jackson in the back of the neck with a machete, kicked him as Jackson reached for the weapon, then picked up the gun and fired a single fatal shot to the back of Jackson’s head. Autenrieth wrapped the body in plastic and used bleach in an apparent effort to clean the scene.

Autenrieth was arrested and charged with second-degree murder; he later pleaded guilty and received a 20-year prison sentence with eligibility for parole after serving 85 percent of the term. Does anyone have additional information about Jackson’s life or connections in St. Joseph that might shed light on what led to this confrontation?
