Skinner died after getting into an altercation with the occupants of a black SUV near Adelaide Street East and Victoria Street on Oct. 19, 2009.
The attack happened at 3 a.m. Skinner had been celebrating his younger sister's birthday and was walking down Adelaide away from the city's Entertainment District.
Police say Skinner was trying to hail a cab when his hand made contact — possibly inadvertently — with the passing SUV.
Kicked to the ground
The occupants got out of the vehicle, kicked Skinner to the ground, then returned to the vehicle, police allege.
The driver then hit the gas and drove right over Skinner and away from the scene, investigators say.
On Friday, police said they've figured out the make, model, year range and colour of the SUV.
"The investigative team is identifying through various databases potential owners of vehicles in 2009, which in turn will lead us to the driver of this vehicle," Det.-Sgt. Stacy Gallant, who has been working the case, said at a news conference.
Gallant has previously said he's confident of eventually tracking down the SUV's occupants.
"One of these days, we will be knocking on your door," he said last year. "You can expect that to happen."
The victim's mother, Ellen Skinner, also said she's confident they will be found:
"You don't get away with stuff like this, not with the team we have working on it. I think it's important for them to know that they are going to have to answer."
There is still a $150,000 reward for information leading to arrests in the case: $50,000 from Toronto police and $100,000 raised by the family.
