OREGON CITY The weekend death of a baby born at a home belonging to members of an Oregon church that shuns doctors and medical care in favor of faith healing is being investigated, a newspaper reported Tuesday.

Last year, Raylene and Carl Brent Worthington, both members of the Followers of Christ church in Oregon City, were charged with manslaughter and criminal mistreatment in the death of their 15-month-old daughter from pneumonia and a blood infection.

The Worthingtons ignored serious symptoms that would have caused any reasonable parent to call a doctor or 911, prosecutors said.

The parents of the baby that was born Saturday and died early Sunday morning are also members of the 1,300-member church, law enforcement officials told The Oregonian.

A key question for Clackamas County sheriffs investigators is whether the infant would have survived if the family had sought emergency medical assistance. If the parents were medically negligent, they could face criminal charges, the newspaper said.

Results of an autopsy was performed Sunday havent been released, sheriffs spokesman Jim Strovink said.

A series of child deaths among members of the church prompted Oregon lawmakers in 1999 to eliminate a so-called spiritual-healing defense for certain cases of manslaughter and criminal mistreatment.

The change in the law was put to a test this year when the Worthingtons were put on trial.

The couple said they believed their daughter had a bad cold or the flu and that their prayers were effective. At no point did they consider calling a doctor or taking the child to a hospital.

A Clackamas County jury acquitted the Worthingtons of the more serious manslaughter charge but convicted Brent Worthington of criminal mistreatment. He was sentenced Friday to 60 days in jail and ordered to provide medical care for his other children.

Clackamas County District Attorney John Foote said his office will be very involved in the investigation into last weekends death.

Its going to be very thorough, he said.
