Jurors were shown video of a shooting Tuesday during Day 2 testimony in the murder trial of Jamal Adams.

Adams, 34, is suspected of killing Matthew Overby, a father of six, while Overby sat in the driver’s seat of his truck off Rossville Boulevard in February 2023. Adams is charged with first-degree murder and witness coercion, among other alleged offenses.

On Tuesday, prosecutors called Hamilton County Medical Examiner Steven Cogswell and retired Chattanooga police investigator Greg Mardis to testify before Senior Judge Don Ash in Hamilton County Criminal Court.

The jury also watched video that showed a man dressed in black approach a white truck with a pistol and fire. Prosecutor Paul Moyle questioned Cogswell, who said Overby’s death appeared to be a homicide.
