FBI Witness: No Blood Found In Casey Anthony's Trunk

Casey Anthonys defense team presented testimony this morning from the FBI s forensic DNA expert who had examined evidence in the case. The testimony came as the defense takes center stage during day 20 of Anthonys trial for the first-degree murder of her daughter, 2-year-old Caylee.

Heather Seubert, a certified expert in serology--the study of blood serum and other bodily fluids--testified she worked in the forensic DNA analysis unit at the FBI in Quantico, Va., in 2008. Seubert said she was assigned to the Anthony case and examined several key pieces of evidence.

Seubert reported she tested swabs taken from items in the trunk of Anthonys car, including the spare tire cover and the trunk liner.

All of those items were tested [for the presence of blood] and were negative, the expert testified.

Anthony, 25, is accused of multiple charges, including capital murder, aggravated child abuse, aggravated manslaughter of a child and misleading law enforcement. The prosecution is seeking the death penalty.

Caylee was last seen alive on June 16, 2008. Her disappearance was not reported until July 15, 2008, when Casey Anthonys mother, Cindy Anthony, called 911.

I found out my granddaughter has been taken, she has been missing. I found my daughters car today, [and] it smells like theres been a dead body in the damn car, Cindy Anthony told the dispatcher.

Questioned by police, Casey Anthony alleged her daughter had been abducted by her babysitter. Multiple searches were conducted, and in December 2008, Caylees remains were found near her family home.

During opening arguments, Anthonys attorney, Jose Baez, said his client had invented the story about the babysitter. He also said Caylee died on June 16, 2008.

She never was missing. Caylee Anthony died on June 16, 2008, when she drowned in her familys swimming pool, Baez said.

Prosecutors dismissed the defenses explanation and claimed Anthony killed her child by placing duct tape over her mouth. The remains were then kept in the trunk of Anthonys car for a period of time before being transported to the wooded area where they were recovered, the prosecution alleges.

In addition to testifying about Anthonys vehicle, Seubert said she also examined several items that were taken from Anthonys closet, including clothing investigators believe she wore on June 16, the day Caylee was last seen alive. While several of the items had faint stains, all were negative for the presence of blood, she said.

Prior to Seuberts testimony, Anthonys attorney, Jose Baez, had called Orange County Sheriffs Department crime scene investigator Gerardo Bloise to the stand. Bloise had previously testified for the prosecution, stating that in his personal opinion Anthonys car smelled of human decomposition.

On the stand today, Bloise testified about processing the clothing found in Anthonys room and said that he sent the items to the FBI. He also testified about his examination of a car belonging to Anthonys former boyfriend, Anthony Lazzaro. Bloise explained the process for checking the car for blood and body fluids, all of which were negative.

During cross examination, Prosecutor Linda Drane Burdick asked Bloise if one of the items of clothing had been washed by Anthonys mother, Cindy Anthony, prior to examination.

Yes, she informed me she had washed that particular item, he said.

In regard to Lazzaros vehicle, Burdick asked, Did it smell like there had been a dead body in it? Bloise replied, No.
