The Royal Canadian Mounted Police made the horrific discovery in the early morning at a trailer park in Tisdale, Saskatchewan as they checked on the woman at the request of a relative who feared the worst after not hearing from her the previous day.
"The complainant advised this was not typical behaviour," RCMP spokeswoman Mandy Maier told a nationally-televised press conference.
An investigation led to another residence in Prince Albert, 135 kilometers (85 miles) to the west, where the body of a male suspect in the murders was found.
