Toronto police say they are continuing to search properties across the city linked to a self-employed landscaper who is facing five counts of first-degree murder.
Det. Sgt. Hank Idsinga says investigators are now searching the basement of a property where Bruce McArthur was known to have worked.
McArthur, 66, is charged with first-degree murder in connections with the presumed deaths of Andrew Kinsman, Selim Esen, Majeed Kayhan, Soroush Mahmudi, and Dean Lisowick.
Police said on Monday that investigators had found two planters that held the skeletal remains of three individuals, and Idsinga says more than a dozen planters need to be processed by forensic teams.
He also says investigators hope to begin work excavating a backyard later this week or early next week.
Idsinga says a forensic anthropologist will be coming in for the excavation, which will be done by hand as to not disturb evidence that could be underground.
