Investigators in Medicine Hat say police found Aaron Matthew Eremenko, 44, in serious medical distress Friday when they responded to a 911 call that someone had been shot at a home in the city.
He died later in hospital.
A tactical team entered the home and found Donald Wayne Neufeld, 54, dead.
Police say they believe Neufeld died of a self-inflicted gunshot wound.
Insp. Glen Motz says Eremenko and Neufeld knew each other and that there was some sort of dispute, but police aren't saying any more about the circumstances that led to their deaths.
"It's certainly not random," says Motz. "They were known to each other."
Motz says the men were not related. He says the home where they were found was Neufeld's residence, but he doesn't know why Eremenko was there on Friday.
A handgun was recovered Motz says, although he didn't know the calibre or whether the gun was registered.
Autopsies both bodies will be conducted in Calgary on Monday.
