AUSTIN, Texas (AP) _ One of Siamese twins who were separated in a rare operation died today. She had been given no chance of surviving.

Nichelle Tejeda, who was not quite 4 months old, died at 9:10 a.m., St. Davids Hospital said.

Doctors had said all along that Nichelle was expected to die, because she inherited an infection in the womb that destroyed vital organs.

Her twin sister, Michelle, remains hospitalized in stable condition, St. Davids spokeswoman Robin Stanton said today. The two were born May 15, joined at the head, and were separated Aug. 22 in a 13-hour operation.

Stanton said foster care has been arranged for Michelle, for when she is well enough to leave the hospital. The girls were made temporary wards of the state when a judge ruled their mother, Alicia Tejeda, was incapable of caring for them.

Ms. Tejeda's lawyer, Larry Schaubhut Jr., has said his client has had a problem with illegal drugs but is working to overcome it and would seek counseling and treatment.
