Additional tips saw the number of properties to be searched grow to 75 then 100, some of them outside the city. A team of seven cadaver dogs, some on loan from other GTA police forces, were searching the properties by the second week of May. These searches had concluded by the first week of June. Follow-up investigations had then considered whether additional searches would be required. Between July 4 and 13, twenty police investigators conducted excavations in the forested ravine behind the Leaside property. They began sifting through a large compost pile, then proceeded with the guidance of canine assistance and a forensic anthropologist. They collected human remains almost every day of this search. On July 20, it was announced that the remains belonged to Kayhan, and that the remains of all of McArthur's alleged victims had been identified. Idsinga said that they had no evidence suggesting McArthur was connected to any other deaths, though the investigation into cold cases was continuing. Waterloo Regional Police contacted Ontario's serial predator crime investigations coordinator to inquire about McArthur in the November 2002 disappearance of David MacDermott from downtown Kitchener. Jon Riley of Meaford, Ontario, is another possible victim. He had gone to Toronto to find work in landscaping, planning to stay in a shelter at Church and Wellesley, and disappeared in May 2013. Five victims were noted by investigators for similarities: middle-aged, bearded, patrons of The Black Eagle bar, and self-identified as "bears" (gay men with overtly masculine traits, such as beards). They had also disappeared over holiday weekends: Navaratnam at Labour Day, Faizi after Christmas, Kayhan during Thanksgiving, Esen on Easter, and Kinsman after Toronto Pride. During McArthur's sentencing hearing, prosecutors said that the eight victims had ties to Church and Wellesley and a "social life" in that community, physical similarities which usually included facial hair or a beard, and six were from South Asia or the Middle East. Several of the deceased had characteristics that made them more easily victimized or the crimes easier to conceal, such as moving between temporary residences or keeping aspects of their lives secret. All information should be properly sourced below and is accurate . Notes are intended to briefly show commonalities, vulnerabilities and connections to McArthur. Skandaraj "Skanda" Navaratnam, 40, was last seen in the early morning of September 6, 2010, leaving Zippers, a former gay village bar, with an unknown man. A friend who saw Navaratnam the day before said he was excited about having a dog; he left this pet behind at the bar when he disappeared.
