Police are investigating the city's latest homicide, a domestic incident that turned deadly in Winnipeg's inner city last week.

Police say several bystanders witnessed a man and woman involved in a domestic altercation on May 18, around 5:30 p.m., near the McDonald's restaurant in the 1000-block of Notre Dame Avenue.

A man who witnessed the dispute, concerned about the safety of the woman, intervened and got into a physical altercation with the man. According to police, the man who was involved in the domestic incident was struck and fell to the ground. Police arrived and the man was transported to hospital in critical condition. He died on Friday.

The man who intervened fled the scene prior to police arriving.

Police have identified the victim as 33-year-old Marlon Dean Laronde (Hart) of Winnipeg. Laronde (Hart) has a lengthy record for breaching court orders but not a lot of substantive charges. Last August he was convicted of causing a disturbance and breaching court orders after he tried to steal a bag of day-old donuts at a Robin's Donuts.

Investigators are asking the bystander and anyone else who may have witnessed the incident and have not yet spoken with police to contact them at 204-986-6508.
