Porky's Star Commits Suicide

TMZ broke the story ... Wyatt's body was discovered on October 26 in Maui -- and cops believe the death was a suicide.

Now, Wyatt's wife Silvina Knight tells us, it's true -- Wyatt recently overcame a battle with cancer but the radiation therapy "left him in both physical and emotional pain."

Silvina adds, "He was tired of the pain and after much contemplation, chose to end his life in a beautiful and a serene place."

It's unclear if Silvina was aware of Wyatt's alleged suicide plot before he died -- but she claims, "His Family and friends are devastated. "
