The case against Bennett abruptly collapsed on January 3, 1990, when Charles Stuart's brother Matthew identified Charles as Carol's killer. Matthew admitted that he had driven to meet Stuart that night to help him commit what he had been told was to be an insurance fraud. Upon arrival, Matthew said that he had seen that Carol had been shot, and that his brother had shot himself to make it appear as a carjacking. Matthew took the gun and a bag of valuables, including the couple's wedding rings, and threw them off the Pines River Bridge in Revere. Some of the items, including the gun, were later recovered.
