Gregory Rivera, 51, a retired U.S. Army Staff Sergeant, was fatally shot in his St. Robert, Missouri, home on October 16, 2020. Authorities say the killing grew out of a planned robbery: two men forced their way into Rivera’s residence intending to steal money and firearms, and a confrontation ended with Rivera being shot.

More than six months later, in early May 2021, the Pulaski County Prosecuting Attorney’s office charged Donnie E. Tatman and De-Andre C. Johnson with first-degree murder, armed criminal action, and burglary. Court filings allege the two planned the theft and carried out the break-in; both were held in the Pulaski County Jail without bond.

Reports say the two men faced the possibility of life in prison. Does anyone have information about Rivera, his routines, or sightings in St. Robert around October 2020 that could shed light on this case?
