Casey Anthony Trial – Day 11

Highly technical testimony based on first-of-its-kind air samples kicked off Week 3 of Casey Anthony’s murder trial in Orlando.

But FOX’s Phil Keating says defense attorneys are working to discredit the day’s main witness, arguing he has a financial interest in the technology…

Prosecutors contend the chloroform was used to render Anthony’s daughter, Caylee, unconscious, at which time Casey used duct tape to suffocate the two-year-old.  The defense claims that Caylee drowned in the family swimming pool, and her death was a cover-up to protect Casey’s abusive father.

Casey Anthony faces the death penalty if she’s convicted of first-degree murder in the case.
