The quiet community of Port Colborne has been shaken by tragedy following the death of 42-year-old Mark Pero, whose passing has prompted the Niagara Regional Police Service (NRPS) Homicide Unit to upgrade what began as a weapons investigation into a full homicide inquiry.

According to the NRPS, officers were first called to the scene earlier this week after receiving reports of an incident involving a weapon in the Port Colborne area.

Despite the swift response of emergency personnel and life-saving efforts, Pero sadly succumbed to his injuries, marking a devastating loss for his loved ones and the wider community.

Following his passing, detectives with the NRPS Homicide Unit assumed control of the investigation, working tirelessly to piece together the events that led to this heartbreaking outcome. Authorities have confirmed that the case is being treated as a suspicious death turned homicide, and they are continuing to gather evidence, conduct interviews, and review surveillance footage from the area.

While details surrounding the incident remain limited due to the ongoing investigation, police have reassured residents that there is no immediate threat to public safety. Detectives are urging anyone who may have witnessed anything unusual in the area or who may possess dashcam or security footage from the time of the incident to come forward and assist in bringing clarity and justice to this case.
