As the trial enters the second day, speculation rises about Casey Anthony's carefree activities after her daughter's disappearance. Ultimately, will a jury be swayed by testimonies by those who know her, or will fact speak higher.

ORLANDO, Fla. –  Two former roommates of Casey Anthony's boyfriend testified Wednesday that the mother accused of killing her 2-year-old daughter never appeared worried, depressed or angry even though her toddler had disappeared.

The ex-roommates, Cameron Campana and Nathan Lezniewicz, said they met Caylee in early June 2008, but the girl eventually stopped coming to the apartment. When they asked Anthony about the toddler, both men testified that she told them the child was with her nanny.

Anthony, 25, is charged with first-degree murder in the death of her daughter. If convicted, she could be sentenced to death. She has pleaded not guilty.

The trial began Tuesday with explosive allegations and two very different theories about how the little girl died.

For the first time, prosecutors said Caylee died from three pieces of duct tape being placed over her mouth and nose. Anthony's attorney claimed the toddler drowned in the family pool and the toddler's grandfather helped cover up the accident. The attorney, Jose Baez, also leveled accusations that Anthony was sexually abused by her father, an allegation he disputed when he took the stand Tuesday as the first witness in his daughter's trial.
