Thomas Johnson, 52, was shot and killed at a Spanaway construction site on March 26, 2019. The fatal encounter happened shortly before 3 p.m. in the 1800 block of South Military Road after an argument with his younger brother, Bruce Johnson, 50. A nearby employee heard a gunshot, saw Thomas outside a work truck clutching his chest, then heard a second shot; Thomas fell and was pronounced dead at the scene.

Bruce Johnson fled the scene but later drove to Joint Base Lewis-McChord and surrendered, reportedly admitting he had just shot his brother. A revolver was found on the front seat of his work truck and he was arrested and charged with first-degree murder. Investigators were told the brothers’ relationship had deteriorated after their mother died in a 2010 car accident; Bruce had lived in their mother’s SeaTac home and lost it after failing to pay bills, and a witness said Bruce had spoken of shooting his brother three months before the killing. Bruce told investigators he acted in self-defense and described beliefs that implicated local officials in a plot involving the brothers’ property; his wife Tina Johnson said the brothers had seen each other infrequently and that Bruce was a loving family man.

Is there anyone who knew the Johnson brothers or who was near South Military Road that afternoon and can add detail?
