A pedestrian found an elderly woman lying on the ground conscious but bruised from an attack and mugging that occurred a few minutes earlier. The woman related that the thugs who attacked her took her purse. However, she pulled out a money wallet and told him that they did not find the wallet, which had $2,000 cash in it. After calling 911 to get help for the woman, the pedestrian snatched the wallet from the woman's hands and ran off. It happened so quickly that the woman had no time to react. The authorities caught him soon thereafter, and charged him with robbery and theft charges. What will be the most likely outcome of the robbery charge?
