Attorney: Evidence Weak At Best

A veteran defense attorney on Monday said the evidence in the case is weak at best.

Attorney Diana Tennis said she is not sure the state's case against Anthony is solid.

"There's a big difference between interesting science evidence and evidence that actually gets to a jury," Tennis said.

Authorities on Friday released a report from a Tennessee lab that found five compounds consistent with body decomposition. Tests found evidence of decomposition on a hair strand found in the trunk, described as "microscopically similar" to one found on Caylee's hair brush.

"This whole talk about the 'body farm' and these interesting tests that this one organization is doing is very, very fascinating. It may be good information, but it's also possible that the jury is never going to hear about it," Tennis said.

Tennis cited the example of lie-detector tests, which law enforcement agencies consider credible but courts do not.

"No matter how good the science may be, that doesn't mean the judge is going to let the jury hear about it if it's not completely trustworthy," Tennis said.

A national search for Caylee continues.
