In addition to Casey's boyfriend, investigators with the Orange County Sheriff's Office talked to several of Casey's friends. The investigators were particularly interested in Casey's activities between June 9 and July 15, when she claimed to have been desperately trying to find her daughter.
Amy Huizenga, a close friend of Casey's, said Casey picked her up at the airport at 2:30 p.m. on July 15 and gave her a ride home. That was just two and a half hours after Casey claimed to have received a brief telephone call from her missing daughter. Huizenga said Casey didn't mention anything about Caylee having been kidnapped or that she was even missing.
On Friday, June 27, Casey called Grund and asked him if he wanted to go with her to Fusion, a popular nightclub. She was still trying to cheer him up after the loss of his job with the Police Department. Grund told detectives he asked who was watching Caylee, since he knew Casey had had a falling out with her mother. Casey told him Caylee was at the beach with her nanny.
The date of that call is significant. It was three days after Grund's career with the Orlando Police Department ended, a date he was likely to remember, and 18 days after Casey said her daughter had been kidnapped. Yet, instead of asking her ex-fiancé, with whom she remained close, and who was a former police officer, for help finding her daughter, she asked him to go clubbing.
At 4:30 p.m. on July 16, detectives arrested Casey Anthony for child neglect, filing false official statements, and obstructing a criminal investigation. Without a body, they were hesitant to charge her with murder.
Detective Yuri Melich, the lead investigator, ended his first report with this:
"As of this writing, this agency has fielded and followed up on hundreds of tips. None of these tips have helped corroborate any of [Casey Anthony's] claims. None of [Casey Anthony's] statements regarding Caylee's disappearance have been confirmed whatsoever. To date, almost all of her statements regarding this have been proven false. Caylee Anthony remains missing."
