These are the facts that we have. Although family and friends do not want to accept a murder-suicide, everything police are saying leads to no other conclusion.
"Instead of looking forward to socializing with Ms. Sherman on what was to be the first day of her vacation, friends of the couple are reeling – stunned that the pair were found hanging from a railing partly surrounding their basement lap pool on Friday.
Late Sunday, Toronto police said the couple both died from "ligature neck compression."
The homicide squad is now in charge of the investigation, although police were still classifying the deaths as "suspicious," not a homicide, in their Sunday night statement.

There was no sign of forced entry to the home and no note left behind to explain what had happened, the police source said."

"A police source told the Star that the couple was found together, by their indoor pool, hanging off a nearby structure in a semi-sitting position."

"Sources say investigators found the Shermans, side by side, in their windowless pool room, each with a men’s leather belt wrapped around their necks and tied to the pool railing. Both had on jackets that were pulled “behind their backs” and rolled down over their arms.

"Sources close to the case believe Honey may have been killed in a secondary location in the $6.9 million Old Colony Rd. house and then moved to the location where she was later found with her deceased husband.
“Forensics need to be done and post-mortems on the bodies, but at this stage it appears there was no forced entry and no evidence of anybody else in the house,” a police source said.

"Although there have been some media reports about evidence, police have yet to confirm any specifics beyond cause of death. However, CBC News has learned that the Shermans were found by the pool in their basement and that investigators have found no security cameras inside or outside the home.

But Perry said the fact that police are not looking for suspects suggests investigators believe whatever happened to the Shermans was isolated to the house, between the two of them, and no one else was involved.
He said that while investigators must keep their minds wide open, from what police have so far indicated, a double murder is one of the explanations that likely can be excluded.
"It's [a] very unusual, very unusual way to commit homicide," he said. "Where you have this wonderful couple, standing members of the community, are somehow both dead from a ligature compression of the neck. It's bizarre."
