Read more of our special package that examines the hurdles and advances in the field of forensics.
Hampikian, who holds joint appointments in biology and criminal justice at BSU and heads the Idaho Innocence Project, has been helping people like Tapp for more than 20 years. He works with defense attorneys and police around the world, trying to free innocent people by exploiting the power of DNA forensics—or by exposing its pitfalls. In other instances, such as the notorious Amanda Knox conviction in Italy, he has shown how DNA evidence was false or misconstrued.
Hampikian, 54, who looks a bit like the comedian Bill Maher but with a beard , is affable, funny, and likes aphorisms. His involvement with forensic science was a multiyear courtship. He had done research on the Y chromosome in Australia and was teaching at Clayton State University in Morrow, Georgia, in when an associate of famed criminologist Henry Lee asked him whether science could determine the sex of a person based on traces of saliva left at a crime scene. It could. Later, he was so captivated by the story of Calvin Johnson, who was exonerated by DNA in after spending 16 years in prison for rape, that he helped Johnson write an autobiography, Exit to Freedom.

Hampikian became a founding member of the board of the Georgia Innocence Project, launched in In , he moved to BSU, where, in addition to teaching and doing research in genetics, he helped found the Idaho Innocence Project. Four of his clients were eventually executed. DNA evidence is so powerful because it has firm roots in science and is backed by statistics.
Analysts focus on 13 or more places in the genome, called loci, where humans are extraordinarily diverse. The exact number of repeats at each locus varies from person to person and can range anywhere between the low single digits to the mids. Because we get one copy of each chromosome from our mother and one from our father, there are two numbers for each locus, which appear as peaks on an electropherogram, a chart produced by a genetic analyzer.
The chance that two people have the same pairs at all 13 loci is astronomically low. To reduce the risk of false matches even further, the Federal Bureau of Investigation FBI will soon release new guidelines calling for 20 or more locations. Its accuracy has made DNA evidence virtually unassailable.
A landmark report published by the National Research Council in dismissed most forensics as unproven folk-wisdom but singled out DNA as the one forensic science worthy of the name. Yet in recent years Hampikian and other geneticists have begun to question the technology. A mere 25 or 30 cells will sometimes suffice. This heightened sensitivity can easily create false positives. Analysts are picking up DNA transferred from one person to another by way of an object that both of them have touched, or from one piece of evidence to another by crime scene investigators, lab techs—or when two items jostled against each other in an evidence bag.
Amanda Knox was convicted of murder in Italy based on a vanishingly small amount of DNA found on a knife. That was the case with Amanda Knox, who was accused of stabbing her U. Authorities had accused a local young man named Rudy Guede with sexually assaulting and killing Kercher.
The evidence against him was overwhelming—palm prints, fingerprints, and his DNA on the victim and throughout her room—and he was eventually found guilty. But Italian prosecutors also charged Knox and her boyfriend Raffaele Sollecito with murder. Hampikian's critique was signed by nine other prominent geneticists and made public.
Meanwhile, he had his students mimic part of the investigation in Italy.
They collected five soda cans from the office of BSU's dean of arts and sciences after lunch and put them in individual evidence bags. Then, without changing gloves, they put five newly bought knives into separate evidence bags. Yet that person had not touched or even been in the same room with the knives.follow link

Nevertheless, the Italian court found Knox and Sollecito guilty. They spent 4 years in prison before being freed by an appeals court, only to later be found guilty again. Last spring, after Italian DNA experts reviewed the case, an Italian high court pronounced both innocent.
DNA analysis can become even trickier when a mix of DNA from various potential suspects is found in a single crime scene sample. With a simple sample, analysts look at two sets of peaks at a given locus: one for the victim and one for the perpetrator. At that point the analysis becomes highly subjective.
