Police Comb Slowly Through Explosives-Laden Barrie Home


UPDATE: Authorities continue to discover explosives at a Barrie, Ont. home, with at least one device discovered Saturday, Canadian Press reported.

It's not likely that residents of a Barrie, Ont., neighbourhood will be back home this weekend as police continue to comb through a house that was found to contain explosives.

Fifty-seven people were forced from their homes Thursday evening after investigators found six explosive devices while executing a search warrant on Virgilwood Crescent.

A father and son charged in a 34-year-old homicide case lived in the residence.

When police executed a search warrant at their home on Thursday, investigators found the explosives and various unidentified chemicals.

"There's lots of wiring around the house, lots of wiring into the devices, lots of wires around the back of the house as well," Const. Angela Butler of the Barrie Police Service said.

"We need to take things slowly. It's a step-by-step process. You just can't do everything at once because that may trigger something else. So, again, it's very methodical, very slow, for the safety of the officers inside and everybody here in the community."

Precarious work

Staff Sgt. Norm Meech said the process is taking longer than expected because there are different sorts of explosive devices and because they don't know what the chemicals are.

Local police have been working with the Centre of Forensic Sciences in Ottawa and the Ontario Provincial Police's Urban Search and Rescue Team.

Sgt. Tim Conroy said residents wouldn't be able to go home Saturday and "probably not tomorrow."

The search stops at night for fear that workers will trip an explosive device, he said.

Fifty-four-year-old Donald Feldhoff has been charged with first-degree murder in the 1978 death of 26-year-old Michael Traynor.

His 75-year-old father, William, was charged as an accessory after the fact.

Police say Donald Feldhoff turned himself in on Wednesday, triggering the arrest of his father and the search of the house the pair lived in for decades.
