The Panama City police informed the Mount Washington police that Detective Flaherty in Massachusetts was already conducting an investigation. Several similar scam calls had been placed to Boston-area restaurants, and Flaherty had already pulled surveillance camera footage from a Walmart in Panama City. Following Flaherty's lead, the Mount Washington police used the serial number of the phone card to find out that it had been purchased from a different Walmart than the Walmart that sold the card used for calls to Massachusetts restaurants.
