A Boonton mother was charged after she admitted giving unprescribed medications to her 11-year-old daughter, who was found dead in her apartment Monday, court documents show.

Shay Mooney, 34, was charged with child endangerment after police responded to a call of a deceased child and found Mooney's daughter unresponsive next to a bottle of prescription drugs, according to an affidavit of probable cause.

Mooney told police that her daughter suffered from a medical condition causing pain, but that she had not been prescribed medication by physicians due to her age, the affidavit said.

Mooney said that she suffered from the same condition as her daughter and that she gave her daughter 10 milliliters of Oxycodone, a narcotic used to treat pain, and Seroquel, a brand of medication used to treat mood disorders, along with other medications from her own prescriptions, the affidavit said.

Mooney's apartment appeared in "serious disarray" with medicine, pill bottles and syringes throughout the apartment, the affidavit said.
