RCMP say a 49-year-old man from the community, whose name is not being released until he appears in court, is facing two charges of second-degree murder and one charge of attempted murder.
Forty-four-year-old Robert Wharton and 32-year-old Rosemary Fox died in the shooting and the third victim, a 48-year-old man, was injured.
RCMP Cpl. Dan Moskaluk says the man is currently in the hospital and is in stable condition.
The accused will be making his first court appearance in Penticton Tuesday morning.
