Detective Sergeant Hank Idsinga declined to comment on what Kanagaratnam's immigration status had been at the time of his death, and it's now unknown if he was an asylum seeker. Kanagaratnam was killed sometime between September 3 and December 14 2015, but Idsinga would not elaborate on what brought them to that conclusion.
Human remains belonging to at least seven victims had been found in planters at a Toronto home linked to McArthur's work as a landscaper. The dismembered remains of all the victims - except for Majeed Kayhan - were found in them.
Many of McArthur's alleged victims were the subjects of two previous police probes into the disappearances of men from the city's gay village. Police have not released a cause of death for any of the men.
"This does create basically a wide-open net", Idsinga said at a news conference. Photoshop tools such as the eraser tool, smudge tool and and spot healing brush tool were each used more than 50 times, according to a Post analysis of the metadata.
Investigators did not release the man's name last week, because they still had not been able to notify his next of kin.
"The identification was confirmed with the assistance from an global government agency", said Idsinga, though he would not provide further details.
But even after widely publishing the grizzly photo, Kangaratnam's name wasn't one that police were closely eyeing in relation to the tips.
Idsinga said Kanagaratnam, 37, arrived from Sri Lanka in 2010 and was not on file as missing.
Police have said that McArthur had some sort of relationship with each of his victims, some of which were sexual.
"We have a lot of searches still to do", he said.
Idsinga thanked those who have come forward and provided tips and encouraged anyone who has not heard from police, or who has information about McArthur, to contact investigators. McArthur, the source said, began to target men whom he had no links to and who fewer people would notice missing.
He said the victims in those cases matched the general profile of the first seven men McArthur is accused of killing. Kangaratnam, whose only family in Canada appears to be a few distant cousins, appears to be the latest to follow the pattern.
