A prominent lawyer for Barry and Honey Sherman‘s family says he has retained a former Toronto police homicide detective and other experts to look into the deaths of the couple as officers continue their investigation.

“I have retained a number of forensic experts including Tom Klatt and other distinguished homicide investigators to provide a second lens and to ensure that no stone is left unturned,” Brian Greenspan told Global News Thursday in a brief written statement.

Klatt worked as an investigator for 19 years and was involved in more than 70 murder investigations, according to a biography on his website.

“He received specialized training and developed an expertise in crime scene profiling and statement analysis. Throughout his career, he was involved in several high-profile international murder cases,” the biography read in part.

Barry Sherman and his wife Honey were found inside their Old Colony Road home on Dec. 15. A post-mortem examination found the Shermans died of “ligature neck compression.” Toronto police homicide investigators are treating the deaths as suspicious, but officers haven’t named any potential suspects or released much information about the investigation.

As of Thursday afternoon, a police cruiser remains parked in front of the home as yellow crime scene tape blocks the front of the property. Toronto police spokesperson Mark Pugash told Global News investigators are still going into the home and the measures are needed to protect the crime scene.

When asked about the hiring of private investigators by the Sherman family, Pugash said Toronto police would not be commenting. He also declined to comment on what, if any, information would be shared with those investigators, as well as the police service’s policies on sharing information with private and third-party investigators.

“Our concentration is on the death investigation and that’s where all of our work is going,” Pugash said.

Meanwhile, the Globe and Mail reported that Toronto Mayor John Tory spoke with the Sherman family and relayed concerns to police about information being given to media outlets, including Global News, by various sources.
