Police make appeal to friends of slain rapper

Toronto police say they need the friends of Anthony Spencer to come forward with what they know about the last hours of his life, if investigators are to solve his slaying.

The 23-year-old was an aspiring rapper who died shortly after being dropped off at a Scarborough hospital on Saturday morning.

Police have revealed that Spencer was shot in a Brimley Road recording studio before he died.

Some of Spencer’s friends witnessed the shooting, but police say they are not being forthcoming with investigators about what happened.

On Tuesday, Det. Sgt. Gary Giroux called on Spencer’s friends to “demonstrate their affection and loyalty to him” by telling police what they know.

The slain man’s sister, Susan Spencer, said her family is grappling with the loss of a brother, uncle, father and son.

“He was somebody, he has a family. He’s not just a name in a newspaper, he’s my baby brother,” she said.

Police also revealed Tuesday they are looking at the possibility that Spencer may have offended local gangs with his rap songs.

Giroux said there are no indications that Spencer was a member of a criminal organization.
