Early on Valentine's Day 2000, Nick Kunselman, fifteen, and Stephanie Hart-Grizzell, sixteen, were murdered at a Subway restaurant near Columbine High School. More than two decades later, the case remains unsolved — but that could change. The reward for information leading to the arrest of the individual or individuals who committed this crime, which had been bumped up to $12,000 on February 14, 2020, has now been increased almost tenfold, to $100,000. According to Denver Metro Crime Stoppers, the increase was powered in part by members of the community who wish to remain anonymous, as well as a $10,000 contribution from Franchise World Headquarters LLC, the corporate entity that encompasses Subway.
