According to the Pueblo Chieftain, prosecutors presented 13 days of testimony in which they were unable to present any hard forensic evidence showing where and how Schelling was murdered. Instead, the prosecution opted to present evidence of domestic violence in the couple's relationship. The defense rested without calling a single witness. The jury deliberated less than 3 hours on Monday and found Lucas guilty of first-degree murder. He was sentenced to life in the Colorado Department of Corrections without parole. After Lucas' sentence, Pueblo Police Chief Troy Davenport expressed satisfaction with the conviction. "I want to thank the case agents and the detectives that worked so hard year after year, and certainly the family who, I cannot, still, imagine what it's like to be in their shoes," he told reporters, according to the Pueblo Chieftain. "I just cannot understand what they're going through and what today must mean to them. Justice has been served today." After the verdict, Schelling's family expressed their sadness at her disappearance and presumed death. "She was just a tiny little thing, but she was just so full of life," her mother, Laura Saxton, told reporters. "I just miss everything about her."
