A Florida judge ordered Casey Anthony, whose daughter Caylee is missing, to be held on $500,000 bond and to wear a GPS locating device if she does bond out.

This came after testimony from Anthony, members of her family, and investigators who said they discovered hair samples similar to Caylee's in the trunk of her mother's car.

And that the car smelled of decomposition.

Mother Cindy Anthony started by blowing a kiss to her daughter Casey.

Then mother and daughter began by breaking into tears.

Cindy Anthony says "this is the first thing I've seen caylee or casey in a week."

Anthony assured Judge Stan Strickland that she would abide by his rules and even delegate people to "Casey-sit" if she came back to stay at the family home.

Cindy Anthony says "I can't, I'm not going to handcuff her anywhere. So I will provide someone with her at all times. I've already talked to her friends."

Orange County detectives put their cards on the table, outlining what they call evidence of human decomposition they say they found in Casey Anthony's trunk.

Detective Yuri Melich says "we found hair samples in the trunk of the car that are similar to length and color of that of Casey. We also found a stain inside the trunk of the car that came up under blacklight that's questionable that we need to process."

Cindy and George Anthony agonized hearing the detective testify that their granddaughter Caylee may no longer be alive.

But now that Casey Anthony is aware of detectives suspicions, prosecutors argued, she is a flight risk.

Prosecutor Linda Drain says "the risk of her flight if she is released on some low bond increases exponentially especially now she's heard this additional evidence and that she is their person of interest in what looks to be a homicide investigation."

Anthony was arrested last week after reporting that her daughter had been missing since last month. She's been charged with obstructing the investigation into her daughter's disappearance and could face additional charges.
