Joshua Leo Johnson, vice-president of the Sonoma County Hells Angels, surrendered to Lake County authorities

Joshua Leo Johnson, vice-president of the Sonoma County Hells Angels, surrendered to Lake County authorities in connection with the beating of a rival gang member and a companion at Konocti Vista Casino in June, according to the Lake County Sheriff's Office. Johnson, 35, an iron worker, remains in jail pending a hearing on his $500,000 bail, officials said Tuesday. Two other Hells Angels — Nicolas Felipe Carillo, 32, and Timothy Robert Bianchi, 33 — were arrested during a warrant sweep in Santa Rosa and Petaluma last week, authorities said. A fourth suspect, David Dabbs 32, remains at large. Dabbs also is being sought on a San Diego no-bail warrant for alleging kidnap and torture, according to the Lake County Sheriff's Office. The suspects are charged in the vicious beating of Michael Burns, 39, a rival motorcycle gang member, and Kristopher Perkin, 48, during a tattoo convention at the casino. Perkin was not seriously injured.
