A software designer who testified at the Casey Anthony trial in Florida said he alerted prosecutors and police about a mistake that happened with the design of his software.
John Bradley told The New York Times assertions by the prosecution that Casey Anthony conducted 84 computer searches on the word "chloroform" were based on data that was inaccurate.
Bradley was the chief software developer of CacheBack, a program used by police to verify the searches that Casey Anthony had made on her computer.
The prosecution repeatedly used the finding of 84 visits to suggest that Anthony planned to kill her 2-year-old daughter Caylee.
Bradley said after redesigning his software he discovered that Anthony visited what the prosecution called a crucial Web site only once, not 84 times.
According to website UPI.com, he said his findings were not presented to the jury and the record was never corrected.
"I gave the prosecution everything they needed to present a new report," he said.
Casey Anthony was acquitted of causing Caylee's death on July 6.
One of her attorneys said it was "outrageous" that prosecutors withheld critical information.
The Times said the state's attorney's office in Orlando did not return messages seeking comment.
