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.
Law enforcement agencies have leveraged the access to public databases by uploading crime-scene genealogy data and inferring relatives to potential suspects. [ 7 ] [ 8 ] [ 9 ] Family tree assembly and analysis of demographic identifiers is then carried out by genetic genealogy experts, either working directly for law enforcement agencies or ...
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.

Scientists say using math to sort through DNA could help investigators put stubborn cold cases to rest. The approach combines the relatively new field of forensic genetic genealogy—solving crime ...
STRmix’s technology promises to help solve what has long been an issue in DNA analysis: The tinier the sample and the more complex it is — if it contained genetic material from multiple people ...
This year, genetic genealogy testing from the DNA profile was completed by Parabon NanoLabs in Virginia — which has helped solve a slew of cold cases. The results determined that a possible ...
Convinced one local person committed both crimes, Baker approaches Jeffreys to utilise his scientific technique to solve the murders. The first-ever DNA manhunt follows, involving the blood testing of many men — all in the aid of catching the killer.
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 ...
