Colorado man pleads guilty to rape after first blaming DNA evidence on 'evil twin brother'

A former soldier who, according to The Gazette, claimed that DNA evidence used against him in kidnapping and rape cases implicated his twin brother in the crimes has been sentenced to 20 years to life in prison.

Aaron Lucas pleaded guilty to nine charges -- including indecent exposure, kidnapping, and rape -- related to sexual assaults he committed on girls ranging from in age from 4-years-old to 10-years-old. Prosecutors said DNA evidence linked Aaron Lucas to the crimes, but Lucas insisted that the real perpetrator was his brother, Brian Lucas.

David Shakes, the Fourth Judicial District Court judge who sentenced Aaron Lucas, said that Lucas was in military uniform when he assaulted some of the victims. At the sentencing hearing, the mother of one of the victims said "our daughter was taught to trust the uniform. She went to that uniform when he approached her."

Lucas' parents also spoke at the hearing. His father said that "he could easily be considered a hero for his actions in Afghanistan," but that stress of combat created what he called "a sickness."

Lucas himself testified that "I've been dealing with this for a very, very long time, since I was a child. There's always time to change. There's always time to get better. Please get me treatment as fast as you can, I've been trying for so long."

Lucas' brother, Brian, is also in prison for sexually assaulting young girls. He was arrested for allegedly fondling a sleeping 16-year-old girl at his former mother-in-law's house. While out on bond, he allegedly fondled his children's 18-year-old babysitter.

Brian Lucas was remanded to jail without bond after a judge declared that his behavior indicated that he presents "an immediate public safety issue."
