A homicide investigation is underway in Fort St. John, B.C., after a 60-year-old woman was found dead and a 64-year-old man was rushed to hospital.

Fort St. John RCMP say officers responded to a report of a man with a gun and erected a safety perimeter around a building in the 10000 block of 105 Avenue Tuesday afternoon.

Police say officers entered the building and found a dead woman from Fort St. John and an injured man from Manitoba.

Officers believe the pair knew each other and the act was not random.

Police have not released the names of two and are asking anyone with information to come forward.

Officers are notifying family of the dead woman.
