Hongchi Xiao, a 61-year-old alternative healer from California, was sentenced to 10 years for manslaughter after the death of Danielle Carr-Gomm, a diabetic woman. During a workshop in 2016, Carr-Gomm ceased insulin treatment based on Xiao's advice and later suffered a medical emergency. The court found Xiao guilty of gross negligence for failing to summon help as her condition deteriorated. He had a prior conviction in Australia related to another patient's death. The case highlights the dangers of unregulated alternative medicine practices.
