Jennifer Ford, a juror on the Casey Anthony trial, spoke out Wednesday night on 'Nightline.' While Ford said she felt Anthony "had something to do" with the death of her child, she claimed there simply wasn't enough hard evidence to convict.

"There wasn't enough evidence," she said. "If you're going to charge someone with murder, don't you have to know how they killed someone, or why they might have killed someone, or have ... where/when/why/how? Those are important questions that were not answered."

However, Ford said she believed that Anthony was somehow involved in the death of her two-year-old daughter. "I feel like she had something to do with it. I don't know what and I don't think it's fair to speculate," she said, adding that several jurors cried as the verdict was read because "not guilty doesn't mean innocent."

On Thursday, Anthony was sentenced to four years in jail for lying to investigators, although she could be released as soon as the end of this month, thanks to time already served.
