A death row inmate who is facing imminent execution claims he has evidence showing he didn't handle the murder weapon.
Oscar Smith, 72, is scheduled to be killed via the lethal injection on Thursday, having spent more than 30 years on Tennessee's death row.
He was convicted of murdering his estranged wife Judith Robirds Smith, 35, and her teen sons from a previous marriage - 16-year-old Chad Burnett and 13-year-old Jason Burnett - inside a home in Nashville in 1989.
