An unidentified law enforcement source familiar with the 1987 murder case of Peggy Hettrick says DNA evidence has ruled out Scott Kimball as Hettrick's killer, reports the Fort Collins Coloradoan [2]. In an article published over the weekend, The Denver Post [3] outed Kimball, a serial killer, as a possible suspect in Hettrick's death (for which Timothy Masters was once wrongfully imprisoned).

Still, Colorado Attorney General John Suthers tells 9News [4] there is new progress on the case. "We have additional DNA evidence that causes us to feel very good about the way this case is moving forward," Suthers says. "It's a matter in front of the grand jury, and I cannot say anymore."
