TORONTO -- A serial killer who preyed on men from Toronto's gay village took photographs of his victims' bodies posed in various states of undress and kept the images on his computer, accessing some of them long after the killings.

The Crown provided previously unheard details of Bruce McArthur's eight murders at a sentencing hearing on Monday after the 67-year-old pleaded guilty to the crimes last week.

"Mr. McArthur repeatedly killed people using ligature strangulation through the use of rope," said prosecutor Michael Cantlon. "Mr. McArthur's involvement with each victim did not cease at the end of each killing. Post-death, Mr. McArthur posed the victims before photographing them."

Police arrested McArthur in January 2018 and charged him for the murders of Andrew Kinsman and Selim Esen. They later charged McArthur for the murders of Majeed Kayhan, Dean Lisowick, Soroush Mahmudi, Skandaraj Navaratnam, Abdulbasir Faizi, and Kirushna Kanagaratnam. All of the men had ties to Toronto's gay village.

"For years, members of LGBTQ community believed they were being targeted by a killer," Cantlon said. "They were right."

Many of the victims' families and friends wept in court as Cantlon went through each of the murders.

"Most of the deceased had traits that made victimization more likely or harder to detect," he said. "Some were forced to live parts of their life in secret because of their orientation. Some lack stable housing."

McArthur used those vulnerabilities to his advantage, said Cantlon, who choked up at one point reading the victims names.

Many of the victims met or communicated with McArthur through dating apps, Cantlon said. Most of the killings took place under the pretence of sex at McArthur's home.

"A frequent site of the killings was Mr. McArthur's bedroom," Cantlon said of the murders that occurred between 2010 and 2017.

McArthur kept a large cache of photographs of each of his victims -- when they were alive and dead. Many images showed dead or unconscious naked men wrapped in the same fur coat, some with a cigar in their mouths.

"These photographs were then accessed by Mr. McArthur long after the killings," Cantlon said.

After taking his photographs, McArthur would dismember his victims and dump the body parts in planters around a residential property in midtown Toronto where he stored his landscaping equipment, or in a ravine behind the home.

Court also heard about a man who was found handcuffed to McArthur's bed when police, who had the serial killer under surveillance, rushed in to make their arrest.

McArthur admitted he sexually assaulted and forcibly confined many of his victims before murdering them, Cantlon said.

Police found victims' belongings in McArthur's apartment, including a bracelet, jewelry and a notebook. They also found a duffel bag containing duct tape, a surgical glove, rope, zip ties, a bungee cord and syringes in McArthur's bedroom along with the DNA of several victims inside his van.

Cantlon said Kinsman's disappearance is what led police to a break in the case.

Investigators found Kinsman's calendar with the entry titled "Bruce" dated June 26, 2017 -- the day he disappeared. They also found surveillance footage where Kinsman lived showing him getting into a red Dodge Caravan. They couldn't make out the van's plates or who was driving.

A Dodge dealership worker told police it was a 2004 Dodge Caravan and when they requested information from Ontario's Ministry of Transportation, they received a list of 6,181 red such vehicles made between 2003 and 2006.

Cantlon said the lead detective on the case then cross referenced the name Bruce with those vehicle owners and came back with five matches. Only one had previous contact with police: McArthur.

Court heard police had arrested McArthur in 2016 for assault for choking a man in the back of his van. The man escaped after a struggle, but police but never laid any charges. Court also heard police interviewed McArthur as a witness years earlier in relation to the disappearances of three of the victims.

Later Monday, emotions bubbled over in court as friends and family read out their victim impact statements.

"It saddens me to know Andrew is gone. I miss him very much," said Kinsman's sister Karen Coles. "He wanted to make the world a better place."

Navaratnam's friend said he hoped justice would be served.

"He was a highly intelligent man -- he was almost unbeatable at scrabble," the friend said of the man who went by the name Skanda. "Skanda will never be replaceable to me."

A woman speaking on behalf of the Esen family had harsh words for McArthur and police.

"We can't come to terms with his savage murder," she said. "We also find it hard to believe that the serial killing of eight innocent gay persons went unnoticed for eight years."

The Crown read out a statement by Lisowick's daughter. She said she never knew her father.

"I was told he lived on the streets downtown. Growing up knowing that wasn't easy," she wrote. "I have a child and another baby on the way and unfortunately one day they will ask about my father and where he is and I will have to tell (them) how he was taken away from the world."

Cantlon said McArthur has shown some remorse by waiving his right to a preliminary hearing and pleading guilty to the charges. He said there is no evidence that McArthur has murdered anyone else.
