Authorities say a teenager used her 74-year-old grandmother who suffers from memory loss to cash counterfeit checks.

Alachua County Sheriff's officials say 19-year-old Jennifer Sparacino took her grandmother to a Gainesville Bank of America twice in early May to cash three checks totaling more than $5,400.

Deputies say bank managers told them Sparacino tried earlier to deposit the fraudulent checks using her grandmother's identification. When she wasn't allowed to make the deposit, she left and returned with her grandmother.

Sparacino is jailed on 11 felony charges including grand theft, fraud and exploitation of an elderly person.  She was being held in the Alachua County jail on
