"It's early in the investigation and we're trying to sift through a mountain of information."
Homicide investigators cordoned off several streets as they search for clues as to the man’s last movements.
Police are searching for the person who called the ambulance in the early hours of Wednesday morning.
"Obviously they know something because they called police and we'd like to speak to that person as a matter of urgency," Detective Fogel said.
"I don't believe this is a random attack and therefore members of the community should not be concerned and should carry on with their normal business."
Police believe the house where the body was dumped is not linked to the crime.
