Prosecutors are reviewing the death of a 15-month-old girl a medical examiner says could have been saved if she had been treated with antibiotics.

The Oregonian newspaper quoted Dr. Christopher Young, a deputy state medical examiner, as saying that Ava Worthington died March 2 at home from bacterial bronchial pneumonia and infection.

He said both conditions could have been prevented or treated with antibiotics, and the child's breathing was further compromised by a benign cyst that had never been medically addressed and could have been removed from her neck, The Oregonian reported Saturday.

If prosecuted, the paper said, Ava Worthington's parents would be the first members of Oregon City's Followers of Christ, a fundamentalist Christian denomination, to face charges for failing to seek medical treatment for a gravely ill child.

"We are reviewing the case, and our investigation is progressing," said Greg Horner, Clackamas County chief deputy district attorney. He did not release the parents' names.

When The Associated Press called the number listed for the church Saturday, the person who answered hung up.

Child-abuse detectives recently referred investigative findings to the prosecutors, who are evaluating the case in light of a law passed in 1999 after several faith-healing deaths of children.

"This is the first time that they could be taking a shot at interpreting the law," said state Senate President Peter Courtney, who supported the bill.
