ORLANDO — An FBI forensic expert testified Saturday in Casey Anthony's murder trial that a hair removed from the woman's car showed signs consistent with hair from a dead body.
Anthony is charged with first-degree murder in the death of her 2-year-old daughter, Caylee.
The single, 9-inch strand of light brown hair was the only hair of several collected by investigators to show signs of decomposition, Karen Korsberg Lowe told jurors.
Lowe, who specializes in microscopic hair examinations, described a dark banding seen on hairs from people known to be dead. She said the hair sample she examined showed this banding.
The hair was similar to one pulled from Caylee's hairbrush and was not similar to a hair sample from Anthony, she said.
Lowe was the first of two witnesses called Saturday.
Mike Vincent, an assistant supervisor with the Orange County Sheriff's Office crime scene unit, explained how he collected air samples and a stain from Anthony's car in 2008.
Another crime scene investigator testified Friday that he smelled the odor of human composition when he first opened the door to examine Anthony's car days after her initial arrest in July 2008. Caylee's skeletal remains were found in a wooded area near her grandparents' Orlando home in December 2008.
Anthony, 25, could get the death penalty.
Prosecutors say Caylee suffocated after duct tape was placed over her mouth. They contend that Caylee's decomposing remains were at some point in the trunk of Anthony's car.
Anthony's attorney says that the child accidentally drowned in the family's pool, and that Anthony's father, George Anthony, disposed of her body. George Anthony has denied that allegation.
Testimony will continue Monday.
