Family members of people lost to homicide gathered today in front of the new Denver Crime Lab to memorialize their loved ones on the seventh annual National Day of Remembrance for Murder Victims. Approximately 200 people waited in line, holding posters and pictures, and awaited their turn on the microphone to honor their loved ones. Mayor Michael Hancock, who lost his sister to murder in 2002, was one of the featured speakers. After the speeches, the ceremony ended as volunteers released seven dove-shaped balloons into the air. Our own Scott Lentz was on hand to take photos of the event. See them below. More from our Mile High Murder archive circa April: "Ten unsolved Colorado murders: Read personal stories of the victims."
