IMO, something is off with this guy if LE questioned him 3 times already.

Police have questioned a martial arts instructor three times about his alleged sexual interaction two years ago with an 8-year-old Tracy girl missing since Friday.
Police and the family have confirmed that the man whose name and age police, family and neighbors withheld had reportedly kissed Sandra Cantu on the lips while she was swimming in the mobile home parks pool two years ago. Sandra's 15-year-old brother Thomas Fortin suggested he might be in his 40s or 50s.
The man lives behind the home of Sandra, who was last seen around 4 p.m. Friday before the family reported her missing. More than 73 hours have passed since then.
No one answered the door today at the mans trailer, and neighbors declined to disclose his name. He is not a registered sex offender, according to the California Department of Justice. In fact, the department lists that no registered sex offenders live in the mobile home park. Police already interviewed all the areas registrants.
