Police have identified two of the victims and are working to identify the others. Because the children in the videos were unconscious, they might not realise they are victims, police said.
Campos lived in the Franklin area for 20 years and would often approach children playing at school playgrounds to recruit them for his football team, gaining their trust and then inviting them to his home, police said.
Campos was being held at the Williamson County Criminal Justice Centre on a US$525,000 ($845,000) bond. Additional charges are likely, police said. The jail had no record of an attorney for Campos and no one answered at two phone numbers listed for him in online directories.
