Two 21-year-old women died of smoke inhalation in a weekend house fire in Winnipeg Beach, Man., RCMP said in a release Wednesday.

Lisa Mosher and Ally Bernardin were killed in the blaze that destroyed Mosher's family home on Prospect Street on Sunday morning.

Mosher's 18-year-old brother, Ken Mosher, escaped the burning home with first- and second-degree burns.

The cause of the fire remains under investigation, according to police.

Family members have said the home was a cottage that had been converted into a year-round residence.

A trust account has been created for Bernardin's two-year-old son. Donations can be made at any CIBC location in trust of Carson Kolisnyk.
