Jury foreman explains Casey Anthony acquittal

The jury foreman is now talking about why Casey Anthony was acquitted of murder.

The foreman oversaw jury deliberations, which lasted more than 10 hours.

He spoke to Fox News, but wanted his identity kept private.

After more than 30 days of testimony, he says there are still too many unanswered questions.

"We don't know the cause of death and that was one of the major issues we had addressed. We don't know the cause of death. Everything was speculation."

One point of contention was Casey's car.

The state says Casey killed Caylee, then hid her daughter's body in the trunk of her Pontiac Sunfire.

The car was eventually abandoned by a dumpster and towed.

When George Anthony picked it up, he testified that it smelled like death.

However, there was conflicting testimony from other witnesses who were called to the stand.

"Some people smelled it, some people did not smell it," the foreman said. "So as far as whether or not the body did actually decomposition in that trunk, there is evidence that there could have been the decomposition in there, but again we were looking more towards the cause and the who and the how with that car. You know, there were a lot of people that could get access to that car."

George Anthony is one of them.

The defense argued that George knew more about Caylee's death than he was letting on.

"He had very selective memory for me and that, in itself I always kept in the back of my mind. For every time that he got up there I was just kind on guard for that."

The foreman says the jury was suspicious of George, but didn't believe the allegations of sexual abuse.

He's unsure if George played any role in dumping Caylee's body in the woods.

"I don't know how it got there, how Caylee got there, I can't tell you how or who, but ultimately the body ended up there."

Then there's the question of the duct tape found at the scene.

Prosecutors say it was put over Caylee's mouth and nose to suffocate her.

The jury foreman says he didn't buy the defense's argument that the tape was planted at the scene.

"The one thing that I never really bought was the duct tape was placed at a later time," the foreman said. "You can look at that duct tape and tell that it has been aged. But as far as where the duct tape was, the initial point of where the duct tape was when the body was found that was argued and that's where a lot of the discrepancy was."

With so many unanswered questions the jurors decided to acquit Casey Anthony.

She'll be released from jail Sunday.

Defense attorney Cheney Mason fears for her safety.
