The body of Barreira, 46, was found by a roommate in their home just after 4 p.m. MT Sunday. Miller said Barreira was last heard from Saturday night, leaving 24 hours for police to piece together.

The men lived with other roommates in the southeast community of Southview. Barreira​'s roommates were away over the weekend, but police say they have been co-operative since their return.

Miller said the men's home was not known to police, but aren't saying what was discovered there during their investigation.

An autopsy was done Monday, but the cause of death is not being released.

Barreira has family in Calgary who have been notified of his death, which is the city's second homicide in 2014.
