Shane Gregory Dyson, a 36-year-old man from Jacksonville, was found dead on April 28, 2019, in the kitchen of a home on College Street in the Riverside neighborhood. He had been shot multiple times and was pronounced dead at a hospital shortly after the incident. The Jacksonville Sheriff’s Office detained several people for questioning after responding to reports of a shooting.

The death arose from a domestic dispute that turned violent. Dyson’s ex-fiancée, Jennifer Mathis, 36, was present at the scene and was later taken into custody on unrelated probation-violation charges. Mathis’s mother said Mathis acted in self-defense, and Mathis had a prior history of legal problems, including credit card fraud charges and active probation. Dyson had a criminal record that included convictions for home invasion and cocaine possession and had been released from an eight-year prison sentence in 2013.

Police were investigating who fired the fatal shots and whether the killing would be ruled justifiable self-defense or result in charges. Did anyone in the Riverside area see or hear anything the night of April 28, 2019, that could help clarify what happened?
