PORTLAND, Ore.-The painful and apparently preventable faith-healing death of a 16-year-old Oregon City boy this week brings the secretive Followers of Christ Church back under legal scrutiny, just four months after the boy’s infant niece died in similar circumstances. But unlike the girl’s death, which resulted in criminal mistreatment and manslaughter charges against her mother and father, state law may protect the parents of Neil Jeffrey Beagley, who under state statute was old enough to make his own medical decisions. Beagley died Tuesday after what several dozen church members prayed for what church members call spiritual healing. A medical examiner said the boy died of a bladder constriction that eventually triggered heart failure.
