Casey Anthony may not have cashed in on her infamy yet, but another one of the key players in her murder trial may be getting his own lucrative deal.

Dominic Casey, the private investigator hired by the Casey Anthony and George and Cindy Anthony to investigate the circumstances surrounding Caylee’s disappearance, may be in the process of writing an explosive book about the case, RadarOnline.com has exclusively learned.

“I’ve been contacted by several publishers,” Dominic confirmed to RadarOnline.com.

Casey Anthony’s defense team asked for another mistrial on Monday according to a motion they filed in the afternoon.  Casey, 25, is being tried for the first-degree murder of her two-year-old daughter Caylee Marie, and if convicted she may get the death penalty.  Her defense cited a recent federal court ruling that said Florida’s death penalty statute is unconstitutional and they want Judge Belvin Perry to “declare a mistrial in this case and begin jury selection anew with a non death-qualified jury.”

This is the latest legal maneuver by the defense to declare a mistrial and came just hours after the judge ruled that Casey was competent enough to continue with the trial.  Her lawyers submitted a motion on Saturday to have Casey evaluated by three mental health experts.  The trial was subsequently halted and three doctors met with Casey over the weekend.

On this, day two of the defense’s turn in the Casey Anthony murder trial, her legal team will call more witnesses Friday, and once again, RadarOnline.com will live stream the proceedings, starting at 9am ET.

As the defense continues making its case, the big question remains: Will Casey testify in her own defense? Her legal team is not saying.

It has been three years to the day that little Caylee Anthony died and her mother’s legal team started off their defense by questioning evidence from law enforcement.

On Thursday, Casey Anthony’s lawyer actually got into an argument with the prosecution after he asked FBI technician Heather Seubert if she had performed a paternity test relating to Caylee.  He was trying to show that law enforcement had some suspicion that Casey’s own brother, Lee Athony, was Caylee’s father.  Seubert admitted that she had indeed been asked to test Lee Anthony, to see if he was Caylee’s biological father.

The state attorney Jeff Ashton loudly objected to the line of questioning and that is when the two attorneys started arguing.

Casey Anthony broke down in tears during another day of shocking testimony in the murder trial of her 2-year-old daughter when she heard that Caylee’s bones had been chewed on by wild animals in the woods.

John Schultz, a University of Central Florida forensic anthropology professor, told the jury that two large leg bones that were recovered had “actually been chewed on by animals.”  Casey burst into tears as she heard this testimony.  She was visibly shaken and grabbed tissues and wiped her eyes and face while shaking her head back and forth.  She was comforted by one of her defense attorneys.

Judge Belvin Perry ended the trial early on Thursday after Casey became “ill,” following the display of gruesome photos of her daughter’s skull that was found in December 2008. She has cried through the last few days, never looking up at the evidence photos and keeping her head bowed.

Another day, another sob session for Casey Anthony.

Anthony on Friday broke down for the second day in a row during her trial in an Orlando, Florida courtroom -- RadarOnline.com is live streaming the proceedings -- as the accused murderer saw more pictures of her dead daughter Caylee.

The pictures showed 2-year-old Caylee's skull, vertebrae, and finger bones; forensic anthropologist John Schultz gave chilling expert testimony on the state of the child's remains.

Schultz told the jury the late child's "leg bones ... have actually been chewed on by animals."

It’s not clear if Casey Anthony will be present in court Friday during the 15th day of her murder trial after she suffered an emotional meltdown in court on Thursday – a move that forced the judge to call an early recess for the day.

Testimony is set to resume at 9 am ET, and once again, RadarOnline.com will live stream the proceeding as soon as it starts.

Casey became visibly upset and grew progressively sicker as gruesome photos were shown of her dead daughter’s remains during Thursday’s testimony.

On Thursday, Casey wiped away tears while watching her jailhouse videos in court.

The jury were shown tapes of her parents, George and Cindy Anthony, visiting her in jail and Casey brushed away tears in the courtroom while watching the recordings.

Cindy was shown telling her daughter: “Don’t worry about protecting me, dad or Lee,” which caused Casey to wipe tears away from her face.

She is otherwise just sitting stone-faced as she watches the tapes, showing no emotion as the tapes are played where her contradictory statements are revealed.
