.... Forensic investigators analyzing
suspected homicides must trust that a dead body tells a story. When it comes to the Calgary slayings of five-year-old Nathan O'Brien and his grandparents,
constructing that murder narrative to go to trial could be more challenging without any human remains.
"
The bodies of the three victims have not been found," Calgary Police Chief Rick Hanson announced Monday,
one day before police nevertheless brought three counts of murder against 56-year-old Douglas Garland.
Though such cases are unusual, the absence of victims' bodies does not preclude a murder charge in Canada. A prosecution can still build a solid case, retired Toronto homicide detective Dave Perry said.
....
"It's not really about not having a body; it's about how much evidence do they have without a body," he said.
.... Perry noted that convicted killers Michael Rafferty and Terri-Lynne McClintic, currently serving life sentences for murdering eight-year-old Tori Stafford,
were arrested and charged in May 2009 — two months before the Ontario girl's remains were found and confirmed as being hers.
A Calgary judge in 1987
found Al Dolejs guilty of two counts of second-degree murder for killing his 12-year-old son Paul and 10-year-old daughter Gabi. Their bodies were not located until months after Dolejs was sentenced to life. He eventually brokered a prison transfer deal to lead investigators to his children's remains near Bragg Creek, and died in prison in 2005.
