A Toronto police officer was killed Thursday morning while executing an arrest warrant for a suspected terrorist linked to a shooting at the U.S. consulate in Toronto as well as other shootings that have been tied to an Iran-backed group.

Constable Marc Pinizzotto, an 18-year veteran of the Toronto Police Service, was 43 years old.

The U.S. Department of Justice alleged that the consulate shooting was organized by an Iran-backed terrorist organization called Kata’ib Hizballah.

One suspect was injured and has been hospitalized, while another suspect is still at large. He has been identified as 19-year-old Zara Jabbi and is considered “armed and dangerous,” according to Toronto Police Chief Myron Demkiw.

“I would ask anyone that would see him to call 911 immediately,” Demkiw said.

No one was killed during the consulate shooting last March, when two men were seen getting out of a car, shooting at the building and then driving off.

U.S. Ambassador Pete Hoekstra spoke about this morning’s shooting at a U.S.-Canadian trade conference.

“I don’t know if you’re all aware of it, but a Toronto policeman was killed, I believe, overnight in an investigation that may be linked to the United States,” he said.

“Our thoughts, our prayers are with the family of the police person who was killed,” he added.

Hoekstra described the incident as an “example of the close cooperation that we have in law enforcement between the two countries, how we work together and the risks involved in those types of activities.”

Speaking at a press conference, Demkiw paid tribute to the fallen officer before talking about the incident.

“It is with deep and profound sorrow that I must confirm the death of Police Constable Marc Pinizzotto, age 43, of our Emergency Task Force,” he said. “Marc was shot in the line of duty while conducting a search warrant early this morning in the area of Black Creek and Trethewey Drive.”

The police chief said he met with Pinizzotto’s family, and “words cannot describe the pain they are feeling.” 

“Marc served the Toronto Police Service for 18 years, including 5 years as a specially trained Emergency Task Force unit member,” he added. “This loss will have a profound impact on the Toronto Police family.”

“The investigation that led to the search warrant where Police Constable Marc Pinizzotto was tragically killed concerned a number of shootings, including the shooting at the United States consulate on University Avenue,” the police chief explained. “There were several search warrants executed this morning.”

After identifying the suspect, Demkiw addressed him directly.

“I urge you to turn yourself in,” he said.

Demkiw said that as details unfold the police will notify the public, then thanked the community for their “incredible outpouring of support.”

“The strength, character, and resilience of our members, and the entire policing family, is needed now more than ever.  We will lean on each other as we navigate our way through this devastating tragedy. A hero in life, not death,” he concluded.
