Grays Harbor County Coroner Robert Kegel has identified the two people found dead at Wynoochee Wildwood Saturday as Robert D. Bonnell, 57, and Sabrina A. Valdivia, 40.

“Their home towns are not known to us at this time,” said Kegel.

He said the manner of death appears to be accidental, though “a final determination will be made after the results of toxicology tests are received,” added Kegel.

The couple and a dog were discovered in a small building at the campground north of Montesano on Saturday. Chief Criminal Deputy Brad Johansson with the Grays Harbor County Sheriff’s Office told The Daily World the deaths appeared to be the result of carbon monoxide poisoning from a small portable heater and were believed to be accidental.
