The birth of fingerprinting and the criminal case it was 1st used for PART 2 I can't upload it in the english section sorry. One year after Dawn’s murder, a man named Kelly was having a pint when he confessed that he had impersonated a friend and took the blood test on his behalf, explaining that named friend had asked for this favour because he had already taken the test for another fellow, who was struggling with conviction. Kelly’s friend, a baker called Pitchfork, back when the investingations had been just freshly started, had declared he was with his children at the hour Dawn was killed. Pitchfork had doctored his own passport and inserted Kelly’s photo only to drive him to the test centre and wait outside until it was done. Rumor spread and quickly reached the police that promptly arrested both Kelly and Pitcfork. After DNA testing proved him guilt of both murders, Pitchfork was asked “why Dawn Ashworth?”. He simply shrugged and answered “Opportunity. She was there and I was there”. He was condamned to prison for a minimum of 30 years, which will expire next year. Three decades since DNA fingerprinting was first used in forensics we now have online databases, that replaced the DNA drag-nets in order to keep the files in order and easy to recover quickly. The 1st database was created in UK in 1995. Since 2012 it is sanctioned by law that the files belonging to people that were afterwards found innocent must be erased from these databases. bibliography: https://www.theguardian.com/uk-news/2016/jun/07/killer-dna-evidence-genetic-profiling-criminal-investigation
