A Spring Mills woman faces charges she altered a prescription to get 50 tablets of oxycodone from a local pharmacy in May.

Erica Humphrey, 28, told a narcotics agent from the state Attorney General's Office that she altered a prescription that was for 30 tablets of half a milligram of Alprazolam, according to the charging documents.

Authorities allege Humphrey used a scanner and printer to make the fake prescription she used May 16 at the Rite Aid on North Atherton Street to get oxycodone.

A pharmacist at Rite Aid reported the fraudulent prescription after phoning the doctor whose name was on it, authorities said.

Humphrey was arraigned Thursday by District Judge Leslie Dutchcot. Humphrey is charged with felony and misdemeanor count of possession a controlled substance.

Humphrey is free on $15,000 unsecured bail and awaits a preliminary hearing Thursday.
