Tuscon, AZ (NBC) — The defense in the Casey Anthony trial began its presentation to the jury, tackling some of the state's key evidence.
The first witnesses for the defense were very technical: a crime scene investigator and an FBI Forensic DNA Analyst.
The defense was working to establish what they say is a lack of solid evidence in this case. Lead Counsel Jose Baez focused specifically on key items entered by prosecutors, including the lining from the trunk of Casey Anthony's car, clothes, a shovel borrowed from a neighbor, and duct tape found with Caylee's remains.
It was a contentious start, lined with several objections from the state. There were a number of sidebars between Judge Belvin Perry and attorneys, outside the presence of the jury. At one point, Judge Perry seemed frustrated with both sides.
Then, as court recessed for lunch, the judge again warned attorneys about the contentious and heated nature of the morning session.
