Very little is mentioned of him, other than he is devastated. I have a feeling that he discovered her, as he was initally questioned by police and is considered a witness. It was her family that gave the appeal to the public
I hope he is getting help with the care of the children. (Probably her family is)
By the wording and the behaviour of the RCMP, I have a feeling that they have someone in mind (just my thoughts), and by the appeal they are hoping that this person will step forward and get it off of their chest. (once again, just my hope)
What a shock this must be to them. Suddenly, out of the blue, there is a horrible death in their family.
ps> He may have worked a night shift. We don't know. If so, there is a similar outstanding case here in Edmonton. They believe it was a break and enter gone bad.
