A 19-year-old Indiana woman accused of trying to poison her 11-week-old niece by crushing painkillers and adding the powder to a bottle of breast milk has pleaded guilty to attempted murder. Sarai Rodriguez-Miranda of Fort Wayne entered her plea Monday. The Fort Wayne Journal Gazette reports that Rodriguez-Miranda was angry that her mother was allowing her brother, his fiance and the baby girl to live with them for longer than expected. Doctors found the baby had not been poisoned.
