CacheBack software showed 84 searches for “chloroform” on Anthony computer.
Defense attorney Jose Baez called them a part of the state’s “fantasy of forensics” — computer searches for “chloroform” prosecutors said showed Casey Anthony had planned to kill her daughter.
Now, the man whose software investigators cited when they claimed the term had been searched for 84 times on the Anthony computer has cast doubt on the legitimacy of that key evidence in the case.
She had faced a first-degree murder charge in the high-profile trial, and the computer searches were considered a key facet of the state’s argument that the toddler’s death was a premeditated act.
Prosecutors cited a report prepared by a software program called CacheBack, which the state argued showed 84 web searches for chloroform being made on the Anthony computer.
The defense would later contradict the CacheBack report with a separate report generated by another program, NetAnalysis. That report returned only one search result for chloroform.
Last week, CacheBack CEO John Bradley posted a statement on his website, acknowledging that the 84-search result was an error, and criticizing the state for its use of flawed data.
It was Bradley who introduced those results as a witness for the defense. On the stand, he was asked to testify about a CacheBack report “that I had never seen before,” he wrote on his website.
He was not told, he claims, that a NetAnalysis search had returned a different result, and did not hear about the other search until it was referenced by the defense under direct examination.
He realized that the CacheBack data was incorrect, and produced a corrected report, Bradley’s statement said. However, he says his attempts to return to Florida to correct his testimony were rebuffed.
“Since the fate of woman’s life could lay in this critical piece of information, I did everything in my power to remedy the situation, or at least mitigate the issue — once I became aware of it,” he wrote.
In his lengthy statement, Bradley, who could not be reached Tuesday evening, criticized sheriff’s investigators who he said “selectively omitted” information about the NetAnalysis report.
“We stand by the integrity of the investigation and our partnership with the State Attorney’s Office,” Nieves, a sheriff’s spokesman, said in a statement.
In a N.Y. Times article on Tuesday revealing the errors, defense attorney Cheney Mason accused the state of withholding information about the apparent errors in the key evidence.
“If in fact this is true, and the prosecution concealed this new information, it is more than shame on them,” Mason told the Times. “It is outrageous.”
In a statement on Tuesday, state prosecutors said they are “dismayed at the suggestion made by the defense that prosecutors would withhold exculpatory material.”
“Court records show that the defense was completely aware of the issues, utilizing these facts at trial,” the State Attorney’s Office said. The statement specifically cited Baez’s closing argument.
