Darius Sims, 29, was killed inside his Gary, Indiana, home in the early morning hours of June 9, 2023, following a domestic dispute. The woman called the children’s father, Dyequan Kizer, and an argument over speakerphone escalated into shouting between Sims and Kizer. A witness said Sims helped the woman gather belongings and there was no physical altercation between them.

Kizer, a Chicago resident, drove to the home, and after he arrived he shot Sims once in the chest. A witness told police Sims was unarmed. Sims collapsed and was taken to a local hospital, where he was pronounced dead at 3:52 a.m. Kizer initially left in a red Hyundai but returned and was taken into custody. He was charged with murder and held without bail.

In April 2025 Kizer pleaded guilty to voluntary manslaughter under sudden heat; a judge sentenced him to 20 years in prison in September 2025. The Indiana Court of Appeals unanimously upheld that sentence in February 2026. Does anyone have information about the events at the Madison Street residence that night?
