Williams was last seen Sunday night by his wife in their Marin County home prior to her going to bed Sunday night, the department said. He was discovered in another room the following morning with a belt around his neck by his personal assistant.
The toxicology is still ongoing and will take two to six weeks to determine whether there were any drugs or alcohol in his system. Authorities said Williams had been seeking treatment for depression.
