Lumber Baron Inn

John Mouat, a Scottish immigrant who made his fortune in lumber — his company put up more than 200 buildings in Denver between 1889 and 1892 — built this 8,500-square-foot mansion in 1890. It declined over the following decades into a run-down apartment building, and on October 13, 1970, two teenagers were found dead in one of its bedrooms: Cara Lee Knoche, 17, who had been raped and strangled, and her friend Marianne Weaver, 18, shot to death after apparently walking in on the attack. The case remains unsolved, and both women are listed in Colorado's official cold case registry. The mansion was restored and reopened in 1991 as the Lumber Baron Inn. Guests and staff have reported the sighting of a young woman on the stairs and phantom footsteps through the building.
