A violent crime happened at the last place a missing five-year-old boy and his grandparents were seen, Calgary police said Friday
“We remain hopeful that we will find them alive," said Andrus, who is with the Calgary Police Service's homicide unit.
“But based on the evidence, I would say someone would be in medical distress."
Andrus said they are not able to say how many people may be in medical distress, but said they have "sent the exhibits away," and are awaiting results.
