UPDATE: Court hears gruesome details of Bruce McArthur's 8 murders

The prosecutor in the case of a serial killer who preyed on men in Toronto's gay village says Bruce McArthur strangled many of his victims with a rope and pipe and took photographs of their bodies after their deaths.

Crown attorney Michael Cantlon is going through a detailed agreed statement of facts at a sentencing hearing for 67-year-old McArthur, who pleaded guilty last week to first-degree murder in the deaths of eight men over a seven-year period.

Cantlon says McArthur posed many of his victims' bodies for photographs after the murders, and stored the images on various digital devices in his apartment.

He says police found the photographs in a covert operation during which they copied part of McArthur's computer hard drive.

Cantlon says McArthur posed at least one victim with a cigar in his mouth.

The prosecutor warned victims' family, friends and others in the courtroom that the specifics of the murders will be gruesome and may even cause some to be sick.
