Ex-roommates of Casey Anthony's boyfriend testify

ORLANDO, Fla. – Two former roommates of Casey Anthony's boyfriend are testifying that she stayed at their apartment in June 2008 when her daughter Caylee was missing.

Nathan Lezniewicz and Cameron Campana testified Wednesday that they never saw the 25-year-old Anthony angry, sad or depressed while she was staying at their Orlando apartment. Both said they met Caylee in early June, but then the toddler stopped coming to the apartment.

When the men asked Anthony about the child's whereabouts, she told them the girl was with her nanny.

Anthony is charged with first-degree murder. If convicted, she could be sentenced to death.

Prosecutors say Caylee died from three pieces of duct tape placed over her mouth and nose. A defense attorney claims the toddler drowned.

This is the second day of the trial.
