for them, the dark cloud that lay over the family name for nearly a decade had lifted. we re part of the peterson family. and we are not afraid to say it. we so were stigmatized before, you know, and, like, hiding it. still, the second trial loomed. but working in michael s favor was the fact that the prosecutor would have to try a very different much weaker case. duane deaver had been fired from his job and some of the state s critical blood evidence would be inadmissible. i think their case is very, very badly compromised because of deaver. he was all over the crime scene. and there was another important victory for peterson s side. what types of services did you perform? oh wow, that s that s pretty broad. brad, the male escort, a sensational centerpiece of the prosecution s case, wouldn t be part of a second trial either, a judge said. the escort had been revealed in a search that was deemed illegal. the search warrant that resulted in the seizure of the compute
my opinion is that this is scene of a beating. he was a star witness for the prosecution in the peterson trial, the blood pattern expert who put michael peterson in the staircase bludgeoning his wife, reporter julia sims. you talked to the jurors here in this case, julia. how important was the blood expert, deaver s testimony? that blood evidence was critical. here s a guy who has been doing this for years for the state. look at what his experiment showed. it s got to be the truth. he d been key in other cases, too. the newspaper recounted the story of a man who was sent to prison for murder after deaver s lab report suggested a stain on the man s car was the victim s blood. and it turned out not to be blood. wasn t blood at all. huh-uh, no. and deaver knew, and didn t disclose it? deaver knew that that was not blood and didn t disclose it. that man s conviction was overturned. gregory f. taylor is innocent of the charge of first-degree murder.
he said he had been involved in 500 cases, involving blood spatter. was that true? no. in fact, he had been involved in 54 cases. he said he had written 200 reports involving blood spatter analysis. not true. he said that he had been to the scenes of falls 15 times. in fact, he had never been to a scene of a fall. what s more remember deaver s conclusion at the trial that the blood stain on peterson s shorts proved he had been standing over his wife beating her. the individual wearing these pants at the time of that impact was in close proximity to source of blood when it was impacted. turns out he d conducted an experiment pre-trial, and it was videotaped, too. watch. on the second attempt, peterson says it looks as though deaver and another agent got the results they wanted. his assistant does a little jig. oh. a little happy end zone dance? yeah.
and there was more evidence of questionable conduct linked to deaver. the newspaper investigation suggested that the methodology behind some of the blood pattern experiments he was involved in was flawed, designed to produce pro-prosecution results. like this test conducted for a 2009 murder case. deaver, videotaping the experiment, was attempting to match a blood stain on the shirt of the accused. oh, even better. holy cow. that was a good one. that s a wrap baby. that s a wrap? that s a wrap. just like the movies. right. peterson s attorney, dave rudolf, says it does not look to him like objective science. they come to the belief that someone is guilty. they don t have the the evidence that they think they need to convict the person, and so they make it up. rudolf signed back on to michael s case, this time without pay, and began to dig. he discovered that at the peterson trial, duane deaver had not been truthful about his professional experience on the stand.
