The researchers used data from 17 actual cases to test their model. In each case, the target’s DNA—that of the suspect or the victim—produced anywhere from 200 to 5,000 matches.
DNA evidence linked Curcio to the crime. [122] In March 2009, Sean Hodgson—convicted of 1979 killing of Teresa De Simone, 22, in her car in Southampton—was released after tests proved DNA from the scene was not his. It was later matched to DNA retrieved from the exhumed body of David Lace.

This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26] Data on the racial distribution of profiles suggests that 8.6% of the entire African American population is present in the database compared to only 2% of the white population.
Jayann and Dave Sepich, Katie's parents, began researching the role of DNA in solving crimes.

Using the killer’s DNA from the crime scene, Moore reverse engineered both sides of a family tree until she found the connecting point; Scharf then collected DNA tossed from a truck by the ...
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.
