DENVER (AP) — Police in Denver on Winning ExchangeSunday were investigating a double homicide at a former hotel that is being used to shelter homeless people.

The victims, a man and a woman, were found Saturday night at about 9:20 p.m. in one of the shelter’s residential rooms, said Officer Kurt Barnes with Denver police media relations.

Barnes did not know if the victims were residents and the manner of their death was not immediately released. No arrests had been made.

The shelter is inside a former DoubleTree Hotel in Denver’s Central Park neighborhood.

A nonprofit group that provides affordable housing acquired the 300-room building in November. It’s being leased for transitional housing as city officials try to reduce the number of homeless people in Denver.
