CHAMPAIGN, Ill. - A pediatrician stabbed her 10-year-old son to death and wounded his younger brother, then called police to tell them what she had done, police said Friday.

Dr. Ellen Feinberg, 43, was charged with murder and attempted murder. She appeared in court via video camera from a mental health facility, and a judge ordered her held without bail.

Feinberg called authorities Thursday afternoon and said "she had killed her children and wanted to be killed by the police," according to prosecutor Elizabeth Dobson.

The mother told police they would find her sons in the basement and a bedroom, and a knife in the kitchen sink, Dobson said. Feinberg had blood on her hands, arms and clothes when police arrived, the prosecutor said.

The older boy, Adam, was pronounced dead at a hospital. The younger boy, Matthew, was in critical condition Friday.

At the arraignment, Feinberg's attorney presented a report from a psychiatrist who said Feinberg was unfit to stand trial.

The attack took place in a well-to-do neighborhood of Champaign, about 130 miles south of Chicago. Neighbors said the boys' father is a surgeon.

"They were normal, very nice, the last people you would ever think would have a tragedy like this," neighbor Alan Parker said. "The kids do all the normal things kids do."
