Caylee's Hair Negative For Variety Of Drugs

An FBI lab report released among hundreds of pages of documents made public Friday in the case against Casey Anthony showed hair samples from her daughter's remains revealed negative results for a variety of drugs.

Examiners did not detect alprazolam, known under the trade name Xanax, or diazepam, marketed as Valium, according to the report.

The hair samples were not tested for chloroform, "as this examination is not deemed probative by the FBI Laboratory's Chemistry Unit."

"Although the method used in this analysis allows for the detection of very small amounts of the drugs listed, negative results should not be interpreted as proof that the individual was not exposed to the drugs listed," the report stated.

Anthony, 23, is charged with first-degree murder in the death of 2-year-old Caylee. Six months after Caylee disappeared, the toddler's skeletal remains were found Dec. 11 in a wooded area less than a mile from her east Orange County home.

The bulk of the documents released Friday focused on the discovery of Caylee's remains and why she wasn't found four months earlier, in August.

Orange County meter reader Roy Kronk found Caylee's skeletal remains while on his route. That discovery, however, came after he alerted detectives multiple times about a suspicious bag in the woods in August. One deputy — later identified as Orange County Deputy Richard Cain — failed to follow through on a tip.

The Orange County Sheriff's Office is in the process of firing Cain, whose actions and job performance were the subject of an internal investigation in the wake the discovery. He is appealing the decision.

"You failed to thoroughly investigate the call for service which ultimately delayed the discovery of the remains of Ms. Caylee Anthony," Capt. Larry D. Krantz wrote in the March 30 internal-investigation report.
