In a brief statement Friday, District Attorney Mitch Morrissey said 47-year-old Richard Kirk was charged with one count of first-degree murder in Monday's shooting death of 44-year-old Kristine Ann Kirk.
"This man destroyed lives. He destroyed families," Morrissey said. "We figured that he was killing two women a month. He was maybe the most prolific serial killer in the state of Colorado. I believe we'll link him to more."
