An alleged Canadian serial killer is now facing an eighth murder charge.

Bruce McArthur, 66, has been charged with first-degree murder in the death of Kirushna Kumar Kanagaratnam, 37.

It is the latest charge against McArthur since his arrest in January. Police say he trolled bars in Toronto's 'Gay Village' as well as gay dating apps for victims, predominantly targeting Muslim men from South Asia or the Middle East.

Toronto police Detective Sgt Hank Idsinga said on Monday that Kanagaratnam's remains were found at a home that McArthur used as storage for his landscaping business.

Detective Sgt Hank Idsinga added that there was no evidence linking Kanagaratnam to the city's LGBTQ neighborhood, as there was with the previous seven victims

The dismembered remains of all the named victims except for, Majeed Kayhan, were found in flower planters in this residential backyard, where McArthur stored landscaping equipment

Kanagaratnam arrived from Sri Lanka in 2010 and lived in Scarborough. He has no immediate family in Canada and was never reported as missing.

Investigators said he was identified after they released photographs of the dead man and appealed to the public for help. Idsinga said at the time was a 'last resort' to identify the victim.

Idsinga added that there was no evidence linking Kanagaratnam to the city's LGBTQ neighborhood, as there was with the previous seven victims, reported CTV News.

McArthur has been held since January 18, when he was arrested and initially charged with the murders of Andrew Kinsman, 49, and Selim Esen, 44

Abdulbasir Faizi, 44, an Afghan immigrant was named as the seventh victim of McArthur on Wednesday

Victims (left to right): Skandaraj 'Skanda' Navaratnam, 40; Majeed Kayhan, 58; and Soroush Marmudi, 50; all disappeared between 2010 and 2015

Victims (left to right): Dean Lisowick, 43; Selim Esen, 44; and Andrew Kinsman, 49, all disappeared between April 2016 and June 2017

At a press conference on Wednesday that was broadcast online, Homicide Detective Sergeant Hank Idsinga revealed other new developments in the case.

Three additional positive identifications have been made on the seven sets of human remains recovered in large planters at a home where McArther, a self-employed landscaper, stored work materials.

The newly-identified remains were those of Esen, 44-year-old Abdulbasir Faizi and Dean Lisowick, a 43-year-old homeless man whose murder McArther has already been charged with.

Forensic specialists had previously identified three sets of remains from the planters: Kinsman; Soroush Mahmudi, 50; and Skandaraj 'Skanda' Navaratnam, 40.

A seventh victim, 58-year-old Majeed Kayhan, was not linked to the remains from the planters, but McArthur has also been charged with his murder. Police have not publicly revealed if or whether Kayhan's remains were found.

Idsinga said there was 'at least' one more set of remains from the planters that had yet to be identified, eventually revealed to be Kanagaratnam.

According to Canoe, police will be investigating cold cases that date back to 1975 to see if there are any links to McArthur.

Police will also be searching at least 70 properties where they believe McArthur worked a a landscaper.
