A man who committed suicide in a downtown luxury high-rise Sunday night also caused a hazardous-material scare with the chemical he used to kill himself, authorities said.
The 12th-floor resident in the 1600 Glenarm Place Apartments used hydrogen cyanide, said Denver Fire spokesman Phil Champagne.
The residents in the apartment below him saw a liquid dripping through their vents about 7 p.m., he said.
The 11th and 12th floors were evacuated immediately, and police were monitoring other floors. No one outside the building was ever at risk, Champagne said. Glenarm Place is a 33-story building with 330 units.
Two residents were taken to the hospital, but their conditions were not immediately known.
Hydrogen cyanide is a poisonous, flammable liquid used in industrial processes and has a history in chemical warfare.
No information about the man was released. He was found dead in his closet, Champagne said.
