Five people were found dead in a Colorado apartment on Sunday, and police suspect drugs were involved. “There was some substance inside,” Commerce City Police Chief Clint Nichols said at a press conference. “We don’t know what the substance is.” He added that if narcotics were the culprit, they were powerful and fast-acting. One adult was found alive, along with an infant, who was hospitalized but doing fine. Authorities tested the air and ruled out carbon-monoxide poisoning.
