Toronto police say they have identified a person of interest in the high-profile 2017 homicides of a billionaire philanthropist couple.

However, the force says no arrest has been made related to the murders of Barry and Honey Sherman.

The founder of generic pharmaceutical company Apotex and his wife were killed inside their Toronto mansion in December 2017.

Autopsy results revealed the couple died by “ligature neck compression” and police have said there were no signs of forced entry.

The killings shocked the city and made international headlines.

The family offered up to $10 million for information that would help solve the case, and hired its own team of private investigators.
