A hearing in Casey Anthony's case is set to begin Friday morning in Orlando.
Anthony is charged with first-degree murder in the death of her daughter, Caylee, whose body was found six months after she went missing. She has pleaded not guilty. Prosecutors have said they will ask for the death penalty if Anthony is convicted.
The toddler's remains were found last December in woods near the home where she lived with her mother and grandparents. Although the death was ruled a homicide, a specific cause was never determined.

Last month, Casey Anthony's defense team sought to , the meter reader who helped in the search for Caylee's body, in the girl's death.
Anthony's defense team admits it has no physical evidence to support its theory, CBS News correspondent Kelly Cobiella points out. And Kronk's lawyers say this is just a ploy to deflect blame from the real suspect - Casey Anthony.
Legal analyst Wendy Murphy told Cobiella, "(Caylee's) mother is the one who's charged with a crime here. So, you can point the finger at Mr. Kronk all day long ... it doesn't explain away the evidence against Casey Anthony."
There are no police reports on Kronk, or arrest reports, that have surfaced, Cobiella adds, to substantiate the claims against him. And investigators ruled Kronk out as a possible suspect early in the investigation.
