Constable Marc Pinizzotto was killed on Thursday morning while executing a search warrant. His mother remembers his “tireless” service to all.

Pinizzotto, a 18-year veteran with the Toronto Police Service and member of the Emergency Task Force, was fatally shot Thursday morning during a police raid in North York.

How exactly the raid that ended in the killing of Const. Marc Pinizzotto is linked to the previous shooting at the U.S. Consulate, authorities have not yet said.
