Authorities in eastern Germany say police found the body of a dead newborn in the refrigerator of his mother's apartment.

Prosecution spokesman Dirk Germerodt said Wednesday that an autopsy was under way to determine whether the baby had been born alive. He says the 21-year-old mother from the city of Muehlhausen in Thuringia state was in psychiatric care.

Relatives found a suicide note and reported the young woman missing on Tuesday. Germerodt says that when police tracked her down, she was found in a medical checkup to have just given birth.

Police then searched her home and made the gruesome discovery.
