One Sunday morning he found a dead cat on the road while doing his paper round and took it home in his bag. He relates that he started to dissect it on the dining room table before Sunday lunch, causing a foul smell throughout the house after he ruptured its intestines.
The method has become important in forensic science to assist police detective work, and it has also proved useful in resolving paternity and immigration disputes. Colin Pitchfork was identified and convicted of their murders after samples taken from him matched semen samples taken from the two dead girls.
Not only did Jeffreys's work in this case prove who the real killer was, but it exonerated Richard Buckland, initially a prime suspect, who likely would have spent his life in prison otherwise. The story behind the investigations is told in Joseph Wambaugh 's best selling book The Blooding: The True Story of the Narborough Village Murders and the murders and subsequent solving of the crimes was featured in Episode 1 of the first season of the American TV series Medical Detectives in which Jeffreys himself also appears.
InJeffreys's methods were used to confirm the identity for German prosecutors of the Nazi Dr. Josef Mengelewho had died inby comparing DNA obtained from a femur bone of his exhumed skeleton,  with DNA from his mother and son, in a similar way to paternity testing.
By focusing on just a few of these highly variable minisatellites, DNA profiling made the system more sensitive, more reproducible and amenable to computer databases. It soon became the standard forensic DNA system used in criminal case work and paternity testing worldwide.
The development of DNA amplification by the polymerase chain reaction PCR opened up new approaches to forensic DNA testing, allowing automation, greatly increased sensitivity and a move to alternative marker systems. The most commonly used markers are now variable microsatellitesalso known as short tandem repeats STRswhich Jeffreys first exploited in in the Mengele case.
Sixteen micro satellites, plus a marker for sex determination, are used with the current system developed for the NDNAD, giving a discrimination power of one in over a billion. Under British law, anyone arrested in England, Wales or Northern Ireland has their DNA profile taken and stored on the database whether or not they are convicted different rules apply in Scotland.
Jeffreys has opposed the current use of DNA profiling, where the government has access to that database,  and has instead proposed a database of all people's DNA, access to which would be controlled by an independent third party.The DNA Profiling Deoxyribonucleic acid (DNA) profiling is a laboratory method used by forensic scientists to determine the identification of individuals by their unique DNA signature.
Also known as DNA testing, this method has been used to diagnose potential genetic disorders, identify heritage, and provide forensic evidence.
