The lawyers for accused killer Casey Anthony began their defense case on Thursday, casting doubt on whether a piece of key evidence indicates her involvement in the crime.
MSNBC.com reports Anthony's lawyer relied on the testimony of FBI technician Heather Seubert, who said that the DNA taken from duct tape found on the body of 2-year-old Caylee Anthony did not match her, her mother Casey or her grandparents. Instead, Seubert said, the DNA belonged to a forensic examiner who analyzed the tape.
Defense attorney Jose Baez also pressed Seubert on whether she was able to find any traces of DNA on other key pieces of evidence including a spare tire cover and a shovel found beside Caylee Anthony's remains. The Associated Press reports that Seubert said that none of the items showed any signs of genetic information.
The duct tape is an important part of the prosecution's case, as they contend that Caylee was suffocated by having the place taped over her mouth and nose. However, the defense team, which is expected to call more forensics experts to the stand on Friday, has said the toddler drowned in the family pool, and was not murdered by her mother.
Thursday marked the third anniversary of the last time that Caylee Anthony was seen alive. The toddler was reported missing on July 16, 2008, and after a lengthy investigation her remains were found in the woods near Casey Anthony's house in December of that year, two months after she had been indicted on the murder charge by Orange County police.
Anthony has maintained her innocence throughout the length of the investigation. If convicted, the 25-year-old year old could face the death penalty.
