On Valentine’s Day 1985, Cassandra Rundle and her two children were found slaughtered in their Colorado Springs home. For weeks, police tracked down men who responded to a personal ad she left in the back pages of a newspaper, looking for love. Thirty-five years later, her killer remains free.

The morning of Sept. 14, 2017, Tim Watkins rode his mountain bike up Mt. Herman west of Palmer Lake, just like he had done countless times before. But he never returned, and three days later, a crew of volunteer searchers found his body shot and buried on a hillside near one of his favorite trails.

Colorado Springs police officers arrived at the 3900 block of Constitution Avenue and found Thomas Kinslow lying in the middle of the street a short distance from his residence. He died from multiple gunshot wounds in November 2005.
