A disabled woman who was severely burned in a fire linked to a Prince George gang war has died in hospital and the RCMP say their investigation has now been upgraded to a homicide.

Linda Fredin, 56, owned the house located in a prosperous neighbourhood in Prince George that was targeted in a suspected arson attack last week.

Fredin lived there with her daughter and a man police allege is a key gang member in the area. But that man was behind bars awaiting trial at the time of the fire.

RCMP Constable Lesley Smith says police are still trying to determine who besides Fredin was inside the house when it was set on fire.

"I understand there were a number of individuals that could have been at the residence at the time. Whether or not they escaped is unknown. At this time I would be speculating that she was the only target," said Smith.

In September police seized body armour, a grenade, and a Glock handgun from the house.Fredin, her daughter, and the alleged gang member were all charged with weapons offenses and were scheduled to appear in court on Friday.
