Theobald “Theo” Brooks Lengyel, a former member of the experimental rock band Mr. Bungle, has been convicted of first-degree murder. The 55-year-old musician was sentenced to life in prison for the killing of his girlfriend, 61-year-old Alice “Alyx” Kamakaokalani Herrmann, in Capitola, California.
A Santa Cruz County jury reached a verdict after just one day of deliberation, following a six-week trial. The prosecution presented evidence including an audio recording from Hermann’s phone, in which she pleaded for her life as Lengyel strangled her.
Hermann was reported missing on December 3, 2023. Her remains were eventually discovered in Berkeley’s Tilden Regional Park, leading to Lengyel’s arrest on January 2.
