Toronto Police are appealing for witnesses to come forward, after a 24-year-old homeless man was killed, and found near train tracks on Friday.

The body of George Fawell was found in an area behind Jimmie Simpson Arena on Queen Street East.  Police say the victim was stabbed 'several' times in the checst and neck.

Toronto homicide detective Gary Giroux said this was one of the most vicious cases he has ever come across, adding it took the coroner's office several hours to document all of the external injuries.

He says the attack was 'sustained' and Fawell likely had died before the attack was done.  Giroux also believes the attack was very personal, and that there may be more than one suspect in the case.

Police say people in the area are co-operating with investigators, but Giroux admits that someone knows something, and isn't coming forward.
