The doctor who conducted a psychological assessment of Bruce McArthur after he pled guilty to a vicious attack in 2001 found in her evaluation that there was little risk that McArthur would re-offend.
Dr. Marie-France Dionne interviewed McArthur, who has since been accused of 8 murders, after he assaulted a man in his home with a metal pipe.
McArthur was given a conditional sentence that included no jail time.
Dr. Dionne wrote in her report that the risk of McArthur committing violence again was "very minimal."
She added that McArthur didn't even remember the episode that saw him attack a man.
The doctor noted it was possible that McArthur had an epileptic seizure at the time.
Dionne goes on to report that McArthur shows "no signs of psychopathy" or any kind of personality disorder.
These revelations are in newly unsealed court documents obtained by outlets including the Toronto Star and CBC.
The 66-year old former landscaper is in custody awaiting trial.
He faces 8 counts of first-degree murder in connection to the killings of men who are connected to Toronto's gay village.
