A guilty plea in a series of Charlotte County bank robberies stretching back almost two years. Authorities say 48-year-old Kevin Stone of Tampa will be sentenced to seven years to life in the robberies. Investigators say Stone robbed RBC Bank on Peachland Boulevard in Port Charlotte in 2010 and a Suncoast Schools Federal Credit Union branch on Tamiami Trail in Punta Gorda earlier this year. In both holdups, witnesses told the FBI that Stone threatened customers and bank employees with a hand gun.
