A person has been taken into custody after two women and a man were found dead at two different Calgary homes.

Police say they believe the deaths are linked, but have said little else — offering no information at a Tuesday afternoon news conference about whether the victims and suspect knew each other, whether a weapon has been found or how the victims died.

Asked whether the deaths may have stemmed from a domestic dispute, Duty Staff Sgt. Peter Duchnij similarly said it was too early to comment.

"We're literally four or five hours into this call, so it's really preliminary," said Duchnij.

Officers discovered the first woman's body at a condo complex in the 2000 block of Applevillage Court S.E. — a suburban neighbourhood on the city's outskirts — after receiving a check-on-welfare call about two locations at around 11 a.m. local time.

The second location was in the 10100 block of Hidden Valley Drive N.W., more than 20 kilometres away.

There, they found a man and a woman, both dead.

Police were seen inspecting the trunk of a vehicle in the driveway. The silver car's driver-side window was smashed.

Duchnij said police took a person into custody at one of the scenes, but didn't say which one.

He said police are not seeking other suspects.

'It's scary,' neighbour says

David Camacho lives near the Hidden Valley home. He was surprised to see police there when he returned from work.

"It's scary," Camacho said. "It doesn't feel like it's safe."

Over at Applevillage ​Court, neighbour Andrew Couchman said police activity isn't completely new to him.

"It's kind of weird. Strange. A couple of weeks ago, there was a guy who overdosed at the gas station as I was passing by, so two weeks, two deaths," Couchman said.

"Time to move south. It's shocking."

Gursewak Singh rents a unit in the Applevillage Crescent S.E. complex.

"So far the neighbours seem pretty friendly, whenever I come into the building I talk to them. Looking at this incident, I think we should be more careful," Singh said.

"In future I will be more careful, if anybody is visiting me."
