Ulises Andrade Ayala, 42, was killed on April 26, 2021, at a marijuana grow site on Sherwood Road in Willits, California. He and a second victim, Anwar Ayala Rodriguez, were found decapitated; law enforcement did not recover their severed heads. Christopher Wayne Gamble, 48, was arrested and charged in connection with the deaths.

A Mendocino County jury found Gamble guilty of second-degree murder for the killing of Ulises Andrade Ayala and first-degree murder for the killing of Anwar Ayala Rodriguez. The jury also found true allegations that Gamble personally and intentionally discharged a firearm causing both deaths; he was additionally convicted of felony animal abuse for killing roosters at the scene.

The court imposed consecutive terms that include 15 years to life for the second-degree murder of Ulises Andrade Ayala plus a 25-years-to-life firearm enhancement, life without the possibility of parole for the first-degree murder of Anwar Ayala Rodriguez plus another 25-years-to-life firearm enhancement, and 16 months for the animal abuse conviction. Anyone with information about the victims, their activities on Sherwood Road, or the grow site is asked to come forward.
