Ricky Roybal-Smith, who was recently sentenced to eight decades in prison for murder in two Aurora stabbings, pleaded guilty to second-degree murder and DUI in an unrelated case this week. The plea was dismissed in exchange for a reduced first-degree death charge. Royabal-Smith strangled his cellmate, Vincent Chacon, in Denver’s Downtown Detention Center after being arrested in connection with a hit-and-run. The victims were identified as 27-year-old Jesse Shafer and 61-year‑old Scott Davenport.
