Associated PressTORONTO — Police in Toronto have recovered the remains of at least six people from planters on a property connected to serial killing suspect Bruce McArthur, officials said Thursday. Detective Sgt. Hank Idsinga said the remains, found on property McArthur used as storage in exchange for doing the landscaping, included some from one of the five men McArthur is already charged with killing, Andrew Kinsman. McArthur was arrested Jan. 18 and charged with two counts of murder in connection with the disappearances of Kinsman and Selim Esen, two men last seen in the "Gay Village" district of Toronto. Not long after that, he was charged with the murders of three more men, and police said they were on a wide search for other possible victims. Police expect to file more charges. Investigators are still working to determine the identities of the remains from the property. They haven’t determined if they are the same men or other people. Authorities have checked at least 30 other places where the landscaper was known to have worked, including in some of Toronto’s wealthiest neighborhoods. Police have said they expect to find more remains in the planters they’ve retrieved from around the city. Idsinga said they have about 15 planters now, but he declined to say where they are in examining them. Investigators are also starting to excavate part of the lawn at the home where the new remains were found. Police have set up a large tent and heaters on the property to keep the ground from freezing and a forensic anthropologist arrived at the property on Thursday. Investigators have not yet released complete details, but the 66-year-old McArthur is believed to have met his victims cruising around the city in the van he used for work and on gay dating apps for older and large men with names. In his SilverDaddies profile, McArthur described himself as 5 feet 10 inches tall and 221 pounds and primarily interested in younger men. "I can be a bit shy until I get to know you, but am a romantic at heart," he wrote. On his Facebook page, he posted pictures of his cats, children and grandchildren and of himself dressed as Santa Claus. "There is an extensive digital investigation going on," Idsinga said. "We’re going through computers. We’re going through cellphones. We’re going through online applications and different apps." Edward Royle, a lawyer for McArthur, has declined to comment on the case. McArthur is due back in court Wednesday. He has yet to enter a plea.
