An Indiana woman has been sentenced to 25 years in prison for trying to poison her infant niece by adding crushed painkillers to a bottle of breast milk.

Nineteen-year-old Sarai Rodriguez-Miranda was sentenced Friday after pleading guilty to attempted murder in March.

Authorities say the Fort Wayne woman tried to poison her niece in January 2017 because she was angry that her mother was allowing her brother, his fiance and the then 11-week-old baby to live with them for longer than expected.

Rodriguez-Miranda was arrested in Michigan in September.

Court documents state that a bottle of milk stored in a refrigerator contained enough crushed painkillers to kill an adult. Doctors found the baby wasn't poisoned.

The child's mother told WANE-TV after Friday's hearing that she's "just glad this is over."
