Toronto police allege Andrea White was shot dead on the weekend after two men attended a gravesite memorial in the city's west end, then went to another neighbourhood and started shooting.
Det.-Sgt. Hank Idsinga told reporters on Wednesday night that police were revealing more information about the investigation in order to dispel "numerous unsubstantiated rumours" that had been circulating.
"The persistence of these rumours can undermine the ongoing investigation," Idsinga said, noting that they could also put false blame at the feet of people who weren’t responsible for White’s death.
Idsinga said that, a year ago, a man named Kwado Mensah was shot and killed in the housing co-op on Forest Creek Pathway, where White also lived. A man was later charged with second-degree murder in that shooting. Neither man lived in the co-op, he said.
Police allege that one or both of the men charged in White’s death were friends of Mensah, Idsinga said.
After they attended the memorial at Mensah's gravesite on Saturday, Idsinga alleges they "acted out their anger" by shooting a gun in the housing complex where Mensah was killed.
The detective did not say exactly where Mensah's gravesite is located, only that it is in the west end and "nowhere near" Forest Creek Pathway.
Idsinga told reporters that six shots were fired on Saturday night.
"There was one firearm discharged at the time," he said. "We’re alleging one of the accused was the shooter, the other one was the driver."
Idsinga said the shots were fired "in the direction of Ms. White’s residence and the residences adjacent to her."
Police have previously said that White was fatally wounded on Saturday night, after shots were fired from a Land Rover that drove past her home on Forest Creek Pathway, just after 11 p.m.
Police say White was struck while in her garage. The 33-year-old was helped into her home by family and friends and soon collapsed. Police say she then died in her home.
The slain woman's family has said that White, a mother of four, was a "pillar of the community."
Two men have been charged with first-degree murder.
