Investigators: Caylee Anthony's mom has lied over and over

Here are some of the lies that investigators say Casey Marie Anthony told about the disappearance of her daughter Caylee Marie:

Lie: She last saw 2-year-old Caylee on June 9 after leaving her with a baby sitter at an apartment on South Conway Road.

Truth: That apartment had been vacant since Feb. 29.

Lie: Caylee's baby sitter, Zenaida Gonzalez, had been a family friend for four years and cared for Caylee for 18 months.

Truth: Contacted by detectives, a woman named Zenaida Gonzalez told them she never met Anthony or her missing child.

Lie: Anthony investigated Caylee's disappearance for a month instead of calling 911.

Truth: Two of Anthony's boyfriends told detectives she never acted upset or mentioned her daughter's disappearance.

Lie: Anthony claimed she had been so concerned she told two co-workers at Universal Studios her child had disappeared.

Truth: Neither person she named works at Universal.

Lie: She claimed she worked full time at Universal Studios -- the reason she needed a baby sitter.

Truth: Theme-park officials said Thursday that Anthony has never been an employee.

The Orange County Sheriff's Office arrested Anthony, 22, late Wednesday on charges of child neglect, providing false official statements and obstructing a criminal investigation.

"Based on the repetitive lies that the defendant has told, we do not know with whom the child is or even if the child is alive," wrote Cpl. Yuri Melich of the missing-persons unit.

"As I received information, and relayed it to the defendant after her arrest, she continued to claim ignorance and, at times, laughed about the situation. She failed to show any outward signs of remorse or concern for her missing two-year-old daughter."
