The child has passed through several hospitals and his case has passed through several courts since he was declared brain dead at University of California, Davis Medical Center after cardiac arrest following an apparent asthma attack in April. The life-support fight was similar to the battle over Jahi McMath — a 13-year-old girl who underwent a tonsillectomy and tissue removal at Children's Hospital in Oakland, California, to treat sleep apnea. [...] her family fought to keep her on life support and moved her to New Jersey, which requires medical treatment of patients like McMath who are declared dead but show minimal brain function.
