POINT ROBERTS, Wash. – Carbon monoxide poisoning is being blamed for the deaths of a Point Roberts couple last month.

The Northern Light reports Gail Amundsen and Murray Church were found dead in their home on Thanksgiving.

The couples’ adult children hadn’t heard from their parents for a week and contacted friends who didn’t get an answer when they knocked on the door.

Whatcom County chief deputy sheriff Kevin Hester says the couple likely died in the middle of the night or early in the morning sometime after November 21st.

Firefighters found dangerous levels of carbon monoxide in the home and the Whatcom County Medical Examiner determined that was the cause of death.

A faulty furnace in the newly built home is thought to be the source of the deadly gas.
