This weekend will be an agonizing time for an Uxbridge family as it leads into the first anniversary of the killing of their son on a downtown Toronto street.

Someone driving a dark SUV and his companions got into an early-morning altercation with Chris Skinner near the intersection of Victoria Street and Adelaide Street East in the early-morning hours of Oct. 18, 2009.

By the time it was over, they had beaten Skinner, knocked him to the ground and then drove over his body. He would become Toronto's 43rd homicide victim of 2009.

A $125,000 reward hasn't managed to motivate anyone to step forward and identify who was driving the SUV that night.

In Uxbridge, about a 75-kilometre drive northeast of where Chris died, his mother Ellen worked Friday in her wool shop.

"I'd like to know how they fill their days," she told CTV Toronto about the people in the SUV that night. "I'd like to know what they think about."

Ellen added: "I'd like to ask the question 'why.' I'm pretty sure they can't answer it."

Just before his death, Skinner had parted company with his sister Taryn. They had been celebrating her 23rd birthday. The 27-year-old started walking eastward alone on Adelaide. Some security cameras captured images of him.

There are also a few seconds of a dark SUV driving eastward on Adelaide out of the club district. Around Victoria Street, something happened that led to a confrontation with Skinner, who was gay.

Police suspect Skinner may have been trying to hail a cab and accidentally touched the SUV with his hand.

Some in Toronto's gay community feel that Skinner may have been targeted for his sexual orientation, but Toronto police said at the time they had no evidence to suggest that was a factor.

Hundreds of people held a vigil for Skinner on Oct. 25, 2009 at the site where he died.

Ellen asked anyone with knowledge of the crime to step forward, talk to the police and set the wheels of justice in motion.

"Just imagine. Just image if it was your brother, if it was your father, if it was your son," she said. "Just imagine how you would feel not to have them in your lives any more."

Ellen used to call her son all the time. She can't do that any more.

"We laughed all the time. And I miss the laughing," she said.

CTV Toronto's Austin Delaney reported that police told him although it's been a year, they don't consider the matter to be a cold case.

They do think that one of the people in the SUV must have told someone something about what happened that night.

Police would like those individuals to contact them.

People with information about Skinner's murder are asked to contact Det. Stacey Gallant at 416-808-7410 or Det. Doug Dunstan at 416-808-7406, Crime Stoppers anonymously at 416-222-TIPS (8477), online at www.222tips.com, or text TOR and a message to CRIMES (274637).
