In just two violent hours on Tuesday night, the region saw three shootings and four victims -- including two fatalities.

RCMP officers are on the scene of two shootings - in north Burnaby and Surrey. And the Vancouver Police Department have confirmed a third shooting in East Vancouver.

All the shootings took place between 8 p.m. and 10 p.m.

In the first, in Burnaby, a woman was shot dead and a man seriously injured in a shooting that took place on the 25th floor of a high-rise on Madison Avenue at Dawson, near Lougheed Highway.

It occurred at around 8 p.m. Burnaby RCMP locked down the building, not allowing people to enter or leave.

"At this particular time it's way too early for us to make any sort of assertions if this is gang related or drug related. This could be domestic related for all we know," said CPL. Dale Carr of the Integrated Homicide Investigation, of the Burnaby shooting.

In the second, Surrey RCMP went to the scene of another shooting, on 68th Avenue at 130th Street, in an incident that took place after 8 p.m.

Police say a man in his early 20s is now in stable condition in hospital with gunshot wounds.

And Vancouver police confirmed a fatal shooting at East 3rd Avenue and Kaslo Street at around 10 p.m.. The male victim is in his mid 20s and was slumped over the wheel of his vehicle.

Vancouver police are using sniffer dogs to cover a wide area near the latest shooting, and have blocked the streets from Nanaimo to Renfrew, west to east, and East 1st Avenue to Broadway, north to south.

Earlier in the evening, Surrey RCMP told CTV News they were trying to determine if the first two incidents were connected.
