 A Colorado Springs man is serving 40 years for killing a teenager. KRDO 13's Brynn Carman has more. That was the sentence handed down yesterday to Marshawn Weathington. He was convicted in April of shooting Isaac Jasso last year during a robbery caught on video. The 20-year-old demanded money from the 16-year-old as he was walking home from work, but the two fought and a bullet struck Jasso in the chest. The victim's father spoke out in front of a packed courtroom saying if it was up to him, the punishment would be life for life.
