TORONTO, Ont. – The family of Christopher Skinner marked the third anniversary of his murder, Thursday, with a renewed plea for tips in the case.

Toronto police Det.-Sgt. Stacy Gallant and Skinner’s father, Warren, and sister, Taryn, held a news conference at 10:30 a.m., saying they are hoping their appeal leads to some closure.

Skinner, 27, was beaten and then run over with an SUV at Victoria and Adelaide streets in the entertainment district on Oct. 18, 2009. He was out that night celebrating his sister’s birthday and was engaged to be married.

The person responsible still hasn’t been found, so the family has set up Facebook and Twitter pages in an effort to generate confidential tips via Crime Stoppers on the murder.

Det.-Sgt. Gallant had this message for the killer: “One of these days, myself and my partner will be knocking on your door, and you can expect that to happen.”

Warren, who is a lawyer, pointed out there were definitely witnesses to this crime.

“People inside the vehicle that were not driving probably don’t have a lot to worry about in terms of being criminally responsible,” he said.

There are two monetary rewards leading to an arrest and conviction for those responsible totalling $150,000. Toronto police also released a reward poster.
