Call the young boy Able and the older boy Baker.

Able was using a children's computer to play a game and Baker sat down with him. While Able was on the computer, Baker fondled Able. Able left the computer and went upstairs to his mother, who was using a public Internet computer, and told his mother what had happened. Baker had left the library by the time Able and Mom came back downstairs.

Mom called the cops from the library. The police came, talked the Able and Mom and the librayr staff. One of the staff gave Baker's address to the police, an address retrieved from the library's patron records.

The police went to Baker's house, and he confessed. He was taken to the Juvenile Detention Center.
