A hushed silence fell in the courtroom Thursday morning as jurors in the Casey Anthony trial were shown graphic photos depicting the remains of 2-year-old Caylee Anthony
After Judge Perry warned courtroom spectators with "queasy stomachs" to "control their emotions," the prosecution introduced photos taken on Dec. 11, 2008, in the woods near the Anthony family's Orlando home.
When the grisly images flashed on the screen, Casey Anthony – on trial for the murder of Caylee
– cried, wiping her nose and eyes with a tissue.
The photos followed earlier testimony from sheriff's deputy Edward Turso, who was called to the scene on Dec. 11, after meter reader Roy Kronk reported discovering "a human skull" in the woods.
Also testifying Thursday morning: Casey's brother Lee
, who was recalled to the stand by the prosecution to address questions about Casey's lies
Lee testified that at one point after Caylee's disappearance in June 2008, Casey told him that her nanny "Zanny" – a.k.a. Zenaida Fernandez-Gonzalez, who both sides now say is a fabrication – and "Zanny's" sister had held her down by her wrists at a local park.
Lee Anthony testified that Caylee said Zanny told her she was taking Caylee because Casey "was not being a good mother" and Zanny "wanted to teach her a lesson."
Casey also told her brother that Zanny warned her not to go to the police.
Additionally, Lee testified that Casey told him Zanny was giving her instructions by logging onto Casey's MySpace account. Casey said Zanny had hacked her account and changed the password to "timer55" – 55 being the number of days from when Caylee was taken from her, Casey said, until Caylee's third birthday on Aug. 9.
"Her feeling was that she was going to get her back on that day," Lee testified.
When he left the stand, Casey avoided looking in her brother's direction.
