Using Familial DNA Search May Catch 1970 Murderer
Monday, March 12, 2012
In the early morning of March 11, 1970, the body of eighteen year old, Susan Margaret Long, was found in Aylsham, Norfolk, in the United Kingdom.
On the evening of March 10, 1970, Miss Long went out with her boyfriend in Norwich, a neighboring town. She left at about 10.25pm to catch the bus back to Aylsham. The bus arrived in Aylsham Market Place at 11.10pm. Other passengers confirmed that Susan got off the bus.
Susan had been raped and strangled. The forensic analysis of semen left at the crime scene, revealed that the killer was from a rare blood group. Blood samples were taken from men living in the Aylsham area. In addition, car paint flakes found on Susan's clothing showed that the paint had originally been pompadour blue and then been re-sprayed metallic maroon. But still these valuable clues did not reveal who killed Miss Long.
Operation CHINA has unfortunately, despite extensive work, still not identified the offender. However, 2010 has seen a new line of enquiry with DNA familial comparisons based on a likelihood ratio list which has resulted in new factors being built into familial searches and eventually it may lead to the killer of Miss Long.
