LEONARDTOWN, Md. — A woman from Leonardtown is facing criminal charges after she allegedly attempted to pay for items at a convenience store with a counterfeit $20 bill labeled “Motion Picture Purposes.”

According to charging documents filed in the District Court of Maryland for St. Mary’s County, Amanda Lynn Grumbine, 41, has been formally charged with possession and attempted use of forged currency, a misdemeanor offense that carries a maximum penalty of three years in jail and/or a $1,000 fine.

The incident occurred on April 12, 2025, at the 7-Eleven on North Run Drive in California, Maryland. Deputy A. Ocasio responded to the store after a concerned citizen reported a dispute between a customer and the clerk over what was suspected to be a fake $20 bill.

A store employee told deputies that a white female handed her the $20 bill before briefly walking toward the restroom. When the employee attempted to deposit the bill into the store safe, the scanner rejected it multiple times. Upon closer inspection, the clerk noticed the fine print identifying it as fake.

When the customer returned to the counter, the store employee informed her the bill was counterfeit. The woman, later identified by law enforcement as Grumbine, allegedly became agitated and stated she could “just tear up the bill.” After a brief argument, she left the store—but not before the clerk retained the fake note.

Surveillance footage showed a white woman wearing a gray sweater with images on the front, black leggings, and black-and-pink Hello Kitty shoes. She was seen entering the store with another woman. The pair arrived in a white Honda Accord and entered the store shortly after 1:30 p.m.

While officers reviewed the store’s surveillance footage, a woman called the Emergency Communications Center and reported that she had gone to the store to make a cash deposit for her storage unit. The caller, who identified herself as Grumbine, stated that she believed the store employee had “put fake 20s out to set her up.”

Deputy Ocasio compared the surveillance footage with a Maryland Vehicle Administration photo and confirmed the suspect’s identity.

Court records show the case was filed April 13. A preliminary inquiry is scheduled for May 23 at the St. Mary’s County District Court. The case is being prosecuted by the St. Mary’s County State’s Attorney’s Office.

If convicted, she faces up to three years in jail and a $1,000 fine.

  1. Nice tattoos around her neck.
    The word “lunatic” originates from the Latin word “luna,” meaning “moon,” and the Late Latin “lunaticus,” meaning “moonstruck”. The term originally referred to a type of insanity thought to be influenced by the phases of the moon.
    Maybe she experienced an eclipse.

    1. Perhaps it’s her calendar? I use my iPhone but there’s no reason she couldn’t be using a lunar calendar to keep track of court appearances.
      I just hope I never meet her in a dark alley.
