Skamania County Sheriff Dave Brown says two men tied up a third man to a tree. But first they stripped him of his clothing, made him dig his own grave, and then beat him.
Both suspects have been identified as 25-year old Marcus Bedell and 32-year old Charles Sample. They are expected to be arraigned Tuesday in Skamania County Court.
The victim has been identified as Robert Downey of Vancouver. He was left in the woods near Washugal, where he was eventually found after he worked his way free.
The couple who found Downey took him to a gas station where they called police.
Investigators say the two men did it to get revenge. They claim they did exactly what the victim did to their dog a few weeks ago. Both suspects have been charged with first degree kidnapping, assault, and robbery.
The investigation is ongoing, and the sheriff's office says other arrests may follow.
