A Fairfax County judge ordered a woman charged in the deaths of her two children committed to a state mental hospital for emergency treatment after the woman appeared to be suffering from schizophrenia, psychosis and suicidal tendencies, according to a report from a doctor with the county's jail forensic unit.

Nhoeung Khlaut, 29, of Manassas, was arrested Sunday and charged with two counts of murder after she was found in a closet in a Herndon town house with her 4-year-old son and 11-month-old daughter. Police said a medical examiner's report revealed that the children died of asphyxiation.

Khlaut's attorney said yesterday that she has refused food or water since she was taken to the county jail, where she was placed under a suicide watch.

James E. Wilcox Jr., Khlaut's court-appointed attorney, said yesterday the judge entered the order on the recommendation of a doctor in the jail's forensic unit. Dale Schultz told the court that based on reports from Khlaut's relatives, she appeared to be depressed and suffering from hallucinations.

Juvenile Court Judge Gaylord F. Finch Jr. granted motions yesterday that Khlaut be evaluated for her competency to stand trial and whether she was sane at the time of the offense.
