The Integrated Homicide Investigation Team has taken over the probe into a double-shooting Thursday night.
Sergeant Stephanie Ashton said Monday that one of the men who was shot is not expected to survive his wounds.
A second man remains in hospital with serious injuries.
When police arrived in the 33300 block of Hawthorne Avenue in Abbotsford, two men, aged 21 and 22, were suffering from gunshot wounds.
Ashton said relatives of the dying man have a message for the public:
"The family are urging those individuals wrapped up in this conflict to stop as they do not want to see anymore violence and death as a result of it.
Police said the incident appears to be the result of ongoing conflict in the Townline area.
Last fall police said they believed the gang feud may have been sparked nearly two years ago as the result of a dispute over a date.
The feud started out with acts of vandalism and property crime, according to police, but has escalated to stabbings, gun violence and deadly shootings.
Ashton said police are also asking another motorist to come forward who they believe may have more information.
She said a sedan was spotted driving erratically at 9:20 p.m PT on Thursday March 10. The driver of the sedan cut off another driver who then honked at the car.
Ashton said police have yet to identify the driver who was cut off and are hoping that motorist will contact them.
Police are also asking any members of the public who may have information that might help in the investigation to come forward.
