The jury deliberated for about six hours, beginning at about noon today, following the prosecution's closing argument rebuttal and Judge Belvin Perry's instructions to them.

The sequestered jury of seven women and five men was scheduled to resume deliberating Tuesday at 8:30 a.m. They were chosen from the Tampa Bay area because of exhaustive pretrial media coverage in the Orlando area and have been sequestered in an Orlando hotel. They have listened to 33 days of testimony and another two days of closing arguments.

In Perry's instructions, he told the jury today that Casey Anthony is charged with murder in the first-degree, second-degree murder, manslaughter, third-degree felony murder, aggravated manslaughter of a child, aggravated child abuse and four counts of providing false information to a law enforcement officer.

He went on to explain the criteria for convicting Casey Anthony on each of these charges, and a copy of the instructions was given to the jurors in writing as well.

Perry reminded the jurors that it is not up to the defendant to prove their innocence. He said a defendant choosing not to testify it is not an indication of guilt.

"Whatever verdict you render must be unanimous," Perry said.

Only 12 of the 17 jurors brought in from Pinellas County will participate in deliberations. Five of the jurors are alternates, but were not aware of this during the trial.

The jury had been expected to begin deliberating Sunday, but as closing arguments approached 7 p.m. yesterday, Judge Belvin Perry sent the jurors home for the night, opting to hold court on Independence Day, reports CBS affiliate WKMG.

Prosecutor Jeff Ashton began his rebuttal argument just after 8:30 a.m. today. Ashton defended the expert witnesses called by the prosecution and attempted to poke holes in the defense's theory of how Caylee died.

The prosecution claims Anthony suffocated Caylee with duct tape. The defense claims Anthony accidentally drowned.

If convicted of first-degree murder, Casey Anthony, 25, could face the death penalty.
