The detectives have been very closed-mouthed about their investigation but it would be my opinion they have investigated. However, I have the same belief. There was a man's name who Sarah would mention frequently who both worked at the center and lives in very close proximity to her home. Prior to going to the center Sarah had normal behavior and was not obsessed with men or sex. It is also the belief of Sarah's mother that her daughter's disappearance stems from her relationship with the same man from the center.
