Byron Banks, 39, was fatally shot in Lawrence County, Mississippi, on October 10, 2015. Investigators treated the death as a homicide and pursued a detailed inquiry that included interviews and evidence collection to reconstruct the events that led to the shooting.

Officials said the probe identified a primary suspect with a history of violent behavior and prior disputes with Banks; that person was arrested and charged with murder. Investigators also developed information suggesting other people were involved, either in the killing or in efforts to conceal the crime, and those leads were under active review.

Relatives described the loss as sudden and devastating to family and friends. If anyone has information about Byron Banks, his movements on October 10, 2015, or the people investigators were seeking, please come forward to Lawrence County authorities.
