Jay Holliday told the Denver Post he has listed the home of Wayne and Kathy Harris, where their son and his accomplice, Dylan Klebold, planned their mass murder and stored many of their weapons. Advertisement Holliday's daughter, Jessica, was a Columbine High School student in 1999 when the Colorado community was terrorized. Randy Brown, another local Realtor whose son was threatened by Eric Harris, has been banned from showing the home by the Harrises. "I'd love to get inside and see it and see Eric's room. It is where this entire plot and tragedy began," said Brown. The Harrises could not be reached for comment.
