What began as a walk to watch college football in north St. Louis ended in a fatal street shooting. On Thursday, a judge handed down a 17-year prison sentence to the man who pulled the trigger, closing a grim chapter in a case that investigators have been piecing together since a September 2025 killing.
Sentence handed down
Marvin Byrd, 54, was sentenced to 17 years in prison, according to the St. Louis Post-Dispatch. The paper reported that the punishment was handed down during a Thursday hearing in St. Louis City Circuit Court.
How prosecutors described the shooting
Prosecutors said Byrd and his roommate left their Northwoods home to join a small gathering to watch college football when an argument broke out over money and drugs, according to Law&Crime. The probable-cause affidavit quoted Byrd as saying the shooting followed a “long build-up of frustration,” though he later characterized it as an accident.
Charges and the victim
Earlier reports said Byrd was charged with first-degree murder, armed criminal action, unlawful possession of a firearm and resisting arrest in the death of 58-year-old Dwayne Thomas, who was found with gunshot wounds in the Walnut Park East neighborhood, according to The Independent. Investigators cited local surveillance footage and eyewitness accounts in the charging documents.
Aftermath and next steps
Byrd remains in custody while corrections officials process his prison term and court records are updated, the St. Louis Post-Dispatch reported. The paper noted there was no immediate public comment from his defense attorney or from prosecutors.
Evidence noted by investigators
Court documents reviewed by reporters state that investigators relied on surveillance footage and witness statements to reconstruct what happened at the scene. That material was detailed in the probable-cause affidavit and in filings prosecutors used ahead of sentencing, according to Law&Crime.
