The woman accused of robbing the Bangor Savings Bank on State Street in Bangor Tuesday appeared in federal court this morning, but she didn’t have much to say.25-year-old Matisha Marie Pitts from the Bangor area didn’t respond to federal judge John Woodcock when he asked her direct questions.Her lawyer, Virginia Villa, told the judge Pitts does have a history of treatment for mental illness. Pitts will be held without bail until she undergoes a mental competency evaluation. “I don’t usually move for a competency evaluation without a good reason,” Villa told reporters. “What you saw in the courtroom is a good reason why.”According to court documents, Pitts handed the teller a note stating she had a weapon and demanded cash. The note said if anyone tried to stop her, she’d start shooting. The FBI says Pitts was given nearly $1400 cash, then left in a taxi.Police arrested her a short time later in an apartment on Kenduskeag Avenue. They say she had around $800 in her purse but they didn’t find any weapons.If convicted, pitts faces up to 20-years behind bars.
