The trial of Casey Anthony, who has been charged with the first degree murder of her 3-year old daughter, Caylee Anthony, is set to begin today at Orlando, Florida.

The trial, which is expected to last 7 to 10 weeks, will take place at the Orange County Courthouse presided over by Judge Belvin Perry and jurors were picked outside Orlando, given the publicity of the case.

On May 20, 2011 at the Pinellas County Criminal Justice Center in Clearwater, Florida, a jury of 12 jurors and 5 alternates were sworn in and will ultimately decide the guilt and the fate of Casey Anthony.

If convicted, Casey Anthony could be sentenced to death.

Casey Anthony was arrested on July 16, 2008, for giving false statements, neglect of a child, and obstruction of a criminal investigation. She is also charged with aggravated manslaughter of a child, aggravated child abuse and providing false information to law enforcement.

In her defense, 25-year-old Casey Anthony has pleaded not guilty and said a baby sitter had kidnapped Caylee, who disappeared in July 2008 and was subsequently discovered dead five months later.

As there are no witnesses and confession, the trial will likely focus on forensic data. Casey Anthony's 1998 Pontiac Sunfire car is considered as one of the crucial forensic evidence as the trunk of the vehicle, according to forensic experts, has been tested positive for chloroform and decomposition.
