Michael Hancock speaks on the "unspeakable pain" of his sister's murder (VIDEO)

Michael Hancock.

This week's cover story, "The Victim Lobby," examines the victim rights movement in Colorado -- its remarkable growth and accomplishments, as well as the controversy over who truly "speaks" for victims in court or in the legislature. But few in high places speak as powerfully, or as knowledgeably, about the kind of intimate losses suffered through violent crime than Denver Mayor Michael Hancock, whose sister Karen was killed by her ex-boyfriend in 2002.

Hancock rarely discusses the impact of his sister's death, but he found a fitting forum last month to do just that last month as the keynote speaker at a local gathering outside the Lindsey-Flanigan Courthouse to mark the National Day of Remembrance for Murder Victims. It was, he said, a lesson "about unspeakable pain," one that left him with "a bazillion questions as to why my loved one had to go."

It was also a call to action. Hancock urged the crowd, mostly parents or spouses of homicide victims, to find the "purpose" behind the tragedy in each of their lives. While he spoke, he noted, Travis Forbes was in a courtroom in the building behind him, pleading guilty to first-degree murder in the death of Kenia Monge. "We hold everyone accountable," Hancock said.
