Toronto landscaper Bruce McArthur has been charged with an eighth count of first-degree murder.
Police have identified the alleged victim as Kirushna Kumar Kanagaratnam.
Investigators released the photograph of the man on March 5 and asked for the public’s help in identifying him.
The sprawling investigation into McArthur is now probing cold cases that go as far back as 1975.
Police say they plan to search at least 70 more properties where they believe the McArthur has worked.
