TULLYTOWN (AP) — A suburban Philadelphia mother has been charged with criminal homicide in the alleged poisoning death of her 2-year-old son.

Bucks County authorities announced the charge Tuesday against 42-year-old Jennifer Clarey, alleging that she poisoned Mazikeen Clarey using two prescription medications.

Authorities say lab tests of the boy’s sippy cup— which prosecutors stressed had a childproof lid — found toxic levels of Vicodin. They say toxic levels of the drug were also found in his blood.

Police called to Clarey’s Tullytown home in August for a wellness check found the boy and also reported finding Clarey with apparent self-inflicted wounds to her wrists.

Prosecutors say Clarey has been arraigned and bail has been denied. Court records did not list a defense attorney who could comment on the charges.
