A woman was found dead and another person is still missing after a boat capsized in the Pitt River, south of Munro Creek in the Coquitlam area, RCMP said on Saturday.
RCMP divisional duty officer Insp. Vishal Mathura said officers were called to the area just after 11 a.m.
Three people were rescued out of the water by passing boaters, he said. Those people are being treated for shock and hypothermia.
BC Emergency Health Services said they transported the trio to hospital in unknown condition.
A male and female were still missing as of Saturday afternoon. The adult woman was found deceased later, and a release from Coquitlam RCMP says a 25-year old man is still missing.
RCMP said conditions at the time of the incident were extremely windy, creating large waves with swells and white caps. Police believe those conditions to have contributed to the vessel capsizing.
Mathura said Coquitlam Search and Rescue and a RCMP dive team are continuing to search for the final missing boater.
Police say alcohol and drugs are not factors.
