Neighbours say there were no signs that could have offered a warning of an apparent murder-suicide in Montreal this weekend.
Police believe a retired pizza delivery man was distraught that his relationship with his girlfriend was slipping away, so he killed their two sons and himself.
The mother called police early yesterday when she discovered the bodies of her 72-year-old boyfriend and the boys, aged seven and one.
"If he had to kill him(self) fine, but why he have to touch the kids," the boys' grandfather Roger Breton told CTV News.
One neighbour who says he often had breakfast with the family at a local youth centre describes them as normal people.
He says while the couple argued frequently, he would have never predicted anything like this would happen.
Another man who worked with the dead man says he never suspected something like this could happen.
Autopsies will be conducted on the bodies later this week.
