When Detective Yuri Melich of the Orange County Sheriff's Department began investigating Caylee's disappearance, he found discrepancies in Casey's signed statement.[28] When questioned, Casey said Caylee had been kidnapped by Zenaida Fernandez-Gonzalez, who she also identified as "Zanny", Caylee's nanny. Although Casey had talked about her, Zanny had never been seen by Casey's family or friends, and in fact there was no nanny.[22][29] Casey also told police that she was working at Universal Studios, a lie she had been telling her parents for years. Investigators brought Casey to Universal Studios on July 16, 2008, the day after Caylee was reported missing, and asked her to show them her office.
