A suspected robber in his physical prime thought he saw an easy target outside a Stuart Best Buy. But police said that the 75-year-old victim chased down 29-year-old man, who had just snatched the victim's brand new laptop computer and printer on Sunday. The victim told police he was waiting in front of the store for his wife to pick him up when the man grabbed the packages and ran. Authorities said the suspect made it about 8 feet before the man grabbed him. Moments later, an off-duty deputy saw what was happening and joined the struggle. The man was charged with robbery by sudden snatching and battery on a person over age 65. He was being held on $12,500 bail.
