The “sheer volume” of information in the double murder of Barry and Honey Sherman has been “overwhelming,” say police, who are continuing their probe into the deaths of the Jewish billionaire couple and are still appealing for tips from the public.

“The police investigation has been, and continues to be, active and ongoing,” Insp. Hank Idsinga, head of the Toronto Police Service (TPS) homicide unit, told a press conference at TPS headquarters on Dec. 16.

The work of the private investigative team hired by the Sherman family at the outset of the case has been completed, Idsinga added.

“The Sherman family appreciates the hard work and dedication of the police officers working on this case,” Idsinga told reporters. “They are committed to working with us and have full confidence that the Toronto Police Service will solve this crime.”

Barry and Honey Sherman were found dead in their north Toronto home on Dec. 15, 2017.

Idsinga said police are still asking for tips in the case, despite the depth of the probe.

To date, investigators have obtained 38 judicial authorizations, or warrants, which have resulted in the searches of residential and commercial properties, electronic devices and the production of 73 individual records; 150 items have been submitted for forensic testing; 243 witnesses were interviewed; four terabytes of security video has been obtained; 205 tips have been provided directly to police from the public; 343 tips were sent to police via the private investigative team; and 701 “investigative actions” have been assigned.

“But we are still asking for help,” said Idsinga. “The (Sherman) family and police urge anyone who has reliable information, no matter how small or unimportant that information may seem, to contact police,” either anonymously through Crime Stoppers, or directly to the homicide squad.

He said police have also set up direct email address for tips: [email protected].

Idsinga said he’s encouraging anyone who provided tips to the private investigative team to resubmit them directly to police.

The up to $10-million reward offered by the Sherman family for arrests and convictions in the case is still on offer, he said. The family thanks the public and media, Idsinga added, but “they request that their privacy be respected.”

Idsiniga thanked the family “for their continued support and patience during this very lengthy investigation. Solving this case has always been the priority and responsibility of the TPS.”

However, “given that this is still a very active investigation, there is little by way of investigative details that I’m willing to discuss,” he said.

Idsinga said that media speculation about the case causes him concern, noting that, “We don’t operate on speculation or theories. We operate on evidence. I can’t imagine how disturbing it must be for family and loved ones of these victims to continually read about speculation in the media.”

He said police are in daily contact with members of the family “and we have a very good relationship with them.”

The most challenging aspect of the investigation is that “the sheer volume of information is overwhelming. There’s just a massive volume of information in this case,” he said.

“We’ve been getting a lot of great information from a lot of different sources. I anticipate we’ll be getting a lot more.”

Idsinga called the killings a “targeted murder.”
