Pierre Oliver Ellis, who is wanted by police in the shooting death of a teenager, denies in a hip-hop video posted online that he committed the murder.

Ellis is accused of killing Keyon "Ace" Campbell on Dec. 2, 2007. Police said Campbell was at home in the Finch and Morningside Avenues area playing videogames with friends on the night of his death. When he stepped out to warm up his mother's car at around 1:30 a.m. he was shot.

Campbell made it back inside his home, police said, where he collapsed. His mother tried to revive him but he died after being rushed to hospital.

It was the city's 80th homicide of the year.

In the music video, which is posted under Ellis' emcee name of "Capitol P," the 23-year-old denies killing "Ace" and says that he treated him better than his own brother.

The video includes several gun references and shows Ellis smoking what appears to be marijuana.

"Didn't reach the funeral, hate seeing sad faces," Ellis rhymes at one point. "What you never think I never loaded up my shell cases?"

It has been viewed more than 10,000 times since it was uploaded on Aug. 4, 2009.

Other videos posted online by the Toronto rapper show images of guns, and Ellis surrounded by wads of cash.

On Monday, police issued a warrant for Ellis' arrest for first-degree murder. They described the 23-year-old as black, 5'9" tall with a medium build and black hair. He is considered "armed and dangerous."

They believe he is still in the Toronto area.

In the wake of Campbell's death three years ago, friends and family described him as a bright student and avid basketball player who held down a part-time job.

Police said the teen was known to police but he did not have a criminal record.

Campbell's mother and aunt are expected to speak at a police press conference late Tuesday afternoon, to appeal for Ellis to turn himself in.

Anyone with information about the case is asked to call Det. Sgt. Hank Idsinga at 416-808-7392 or Crime Stoppers anonymously at 416-222-TIPS (8477).
