On the afternoon of October 15, 1966, Anthony left his Philadelphia, Pennsylvania home on his bicycle to ride to the home of his best friend, Jack Marino. They had been together earlier that day and had made plans to go to their respective homes, eat dinner and then meet up again after dinner. Both boys finished their meals and left to ride to the other one's house. When Jack arrived at Anthony's house he learned that Anthony had just left to meet him at his house, he went back home. Once he arrived, his parents said Anthony had not been to the house to see him, so Jack spent the next several hours looking for him around the city but couldn't find him. Anthony never came home that night, but his parents were not concerned because they thought he'd decided to spend the night at Jack's house. They didn't realize anything was wrong until the next morning, after several customers along Anthony's morning paper route called the house to ask why their newspapers hadn't been delivered.
