Alleged serial killer Bruce McArthur has been charged with three more murders. He is now facing five charges of first degree murder.

The 66 year-old landscaper was arrested in Toronto on January 18 on suspicion of killing Andrew Kinsman, 49, and Selim Esen, 44. Both men went missing from the city’s Gay Village.

“We believe he is responsible for the deaths of other men who have yet to be identified,” said Homicide Det.-Sgt. Hank Idsinga at the time.

Idsinga told reporters during a press conference Monday that McArthur had been charged in the deaths of Majeed Kayhan, Soroush Marmudi, and Dean Lisowick.

“To date, the dismembered remains of at least three individuals have been recovered from the backyard of the residence at 53 Mallory Crescent. These remains have not yet been identified. As has been previously reported, Mr. McArthur earned his living as a landscaper,” he said.

“Investigators have identified approximately 30 properties in Toronto where Mr. McArthur worked,” he added. “We have contacted owners of these properties and have conducted searches at the majority of them.”

He asked anyone who has employed McArthur but have yet to have their property searched to contact police.

The Toronto Police Department has faced criticism for initially trying to quell fears that a serial killer was targeting the community. Some questioned if the response was quick enough.

Lisowick, 47, was never reported missing, and is thought to have been a part of the city’s shelter system, the Toronto Star reports. Investigators believe was murdered somewhere between May 2016 and July 2017.

Marmudi, 50, was reported missing in August 2015. Kayhan, 58, was reported missing in October 2012.

Esen disappeared last April and Kinsman in June.

Police officials have revealed that McArthur had a sexual relationship with Kinsman, but have not said if he had one with Esen.

Three of the victims have ties to Toronto’s Gay Village, but the other two “don’t quite fit the profile,” Idsinga said.

“We do believe there are more,” he added. “We have no idea how many more there are going to be. But it certainly encompasses more than the gay community. It encompasses the city of Toronto.”
