Whitehorse Deaths: Two Children Killed, RCMP Investigating


WHITEHORSE - Five people, including two school-age children, were found dead at a home in a Whitehorse suburb Sunday, but the RCMP said they do not suspect foul play.

The bodies of the children, their parents and a male boarder were discovered by a family friend who had gone to check on the house in Porter Creek.

Firefighters called to the scene first entered the house using breathing apparatus, but later deemed it safe to go in without the equipment.

Sgt. Dan Rogers said the deaths are not suspicious and police and the Yukon Coroner's Service are investigating a number of possible causes. He would not say whether an air quality issue, such as carbon monoxide poisoning, was to blame.

"We are not willing to speculate as to what might have happened at this point," he said. “The investigation is continuing.”

He said the five likely died sometime during the last five days.

"The exact timeline is still being determined but we're confident it occurred sometime between Wednesday and Sunday," he said.

Whitehorse Mayor Bev Buckway expressed her condolences, calling the situation "a great tragedy."

During the day Monday, fire officials and Mounties continued to go in and out of the two-storey, A-frame home, some still wearing masks. Outside the house, flowers had been placed at the end of the driveway.

One of the children who died was in Grade 6 at Holy Family Elementary in Porter Creek, while the other was in Grade 8 at Vanier Catholic Secondary School in Riverdale.

Holy Family Principal Ted Hupe said his school's critical response program went into effect Sunday night when teachers were told of the situation.

Both schools held prayer vigils for the children on Monday.

The names of the victims were not immediately released.
