Casey Anthony trial latest: Defense's DNA expert testimony says no blood found in Anthony's trunk

Orlando, Florida -- An investigator at the FBI's crime lab has testified she did not detect blood on pieces of liner taken from the trunk of Casey Anthony's car

The prosecution has maintained Casey put her daughter Caylee's body in the trunk of her Pontiac Sunfire before hiding it in the woods.

Anthony's attorneys have said Casey's father George Anthony helped her dispose of the girl's body. Then later, a meter reader moved the body into the woods.
Abstract...Articles section Heather Seubert, a forensic DNA examiner with the FBI in Quantico, VA, also said she did not find any DNA from other body tissues on the carpet trunk lining and spare tire cover.

Prosecutors said Caylee's mouth had been covered with duct tape. Seubert said she tested a piece of duct tape and found samples of DNA on both sides.

That DNA on the shiny, non-adhesive side belonged to one of the lab examiners; the tape had been contaminated at some point before it was tested.
On the sticky side, the DNA results were limited, but Seubert was able to determine it did not belong to Casey or Caylee Anthony.
A shovel was also tested but didn't reveal enough DNA to meet the lab's reporting requirements, Seubert said.
Clothing taken from Caylee Anthony's body was tested as well, and Seubert said she found no semen on the girl's shirt or shorts.
The shorts also had no signs of blood. A chemical test on the shirt came back positive for the "possible presence of blood," but there wasn't enough material for more detailed follow-up blood testing, Seubert said.
Earlier, a witness who had previously testified for the state was called up by the defense as its first witness.
Gerardo Bloise, a CSI technician with the Orange County Sheriff's Office, discussed inspecting Casey Anthony's bedroom in 2008 and taking some articles of clothing from her closet for testing.
He said he examined the pants Anthony was seen wearing the day Caylee was last seen alive, but did not see any stains of any kind.
He testified Casey's mother had washed the clothing between the day Caylee was last seen and the day he inspected them.
Seubert, the FBI lab worker, listed off nearly a dozen articles of clothing she inspected or tested for blood at the laboratory.
About half of the clothes -- including pants, skirts, and shirts -- had stains that were tested for the presence of blood. All of the tests on clothing came back negative, meaning the stains did not contain blood.
