BALTIMORE (WJZ) -- The grandmother arrested after a 15-month-old was hospitalized following a methadone overdose is now facing additional charges in the case.

55-year-old Judith Anne Badrian Tetreault is being held at the Calvert County Detention Center on no bond for charges of first and second-degree child abuse, attempted poisoning, first-degree assault, neglect of a minor, and distribution of a controlled dangerous substance.

The investigation into Tetreault began after an infant was rushed to a hospital, and it was determined the child was suffering from a methadone overdose.

Authorities found that Tetreault was taking care of the child, and soon after the mother picked her son up, he appeared to be very non-responsive.
