DENVER - A historic four-story building under renovation collapsed in Denver's Highlands neighborhood on Tuesday night.
The building wasn't occupied and no one was injured when the brick structure fell about 7 p.m. at 2727 W. 33rd St., said Denver Fire spokesman Mark Watson.
A photo by 7NEWS photojournalist John Newton showed the four-story building had tumbled to the ground floor, with remnants of some walls still standing.
A passerby saw the collapse and called 911, Watson said. A neighboring house suffered minor damage due to the collapse
