Police believe Tim Bosma was killed May 6, the same night he took two men for a test drive in a truck he had posted for sale online. His body was found this week, burned beyond recognition.
A Toronto man, 27-year-old Dellen Millard, has been charged with first-degree murder, forcible confinement and theft of a vehicle.
Investigators are searching two of his properties in the Waterloo Region — an airport hangar and a farm — and say they have seized an incinerator found on the farm property.
Det.-Sgt. Matt Kavanagh wouldn't say if the incinerator had been used or not.
He expects police will continue searching three vehicles, the hangar and the farm for at least another day.
An anthropologist from the coroner's office is on site at the farm, he said, and it's slow, painstaking work.
"They just look for small fragments, that's all," Kavanagh said. "It's forensic evidence so that's what we're interested in."
Police have also submitted production orders for phone records, he said.
Investigators have not yet determined a motive, they have said.
They are still looking for a second man they say went along for the test drive of Bosma's 2007 Dodge Ram pickup, and at least one more suspect who they say followed behind the truck in another vehicle.
Millard is set to appear next in court by video remand on June 13. His lawyer has said he will plead not guilty.Suggest a correction
