Sheldon Walker, 25, died after being shot in the early hours of January 23, 2021, at the shared residence on Bunnell Drive in the Windy Hill neighborhood of Jacksonville. He was critically injured in an altercation with his half-brother, George Kenneth Litgen, and succumbed to his injuries three days later. The Jacksonville Sheriff’s Office noted both men had a history of domestic violence, which investigators say likely contributed to the confrontation.

George Litgen, 50, was arrested at the scene. He was initially charged with attempted murder, shooting deadly missiles into a building, and possession of a firearm by a convicted felon; those charges were later upgraded to murder after Walker’s death. Family members described Walker as kind and humorous, and his organ donations reportedly saved four lives.

What details about the relationship between the two men or the events that night might help explain how the dispute escalated to gunfire?
