The Australian expert described Anwar Ibrahim's case where the chemist managed to retrieve DNA after 56 hours from the rectum and left another 48 hours in the open, as one of the longest documented discoveries in the world if the results could be believed.
Dr Brian McDonald said it is extremely rare that you could find sperm after 113 hours in the rectum, he said in referring to a 1997 article shown to him two days ago by the prosecution.
“That case, along with the 1982 case (which earlier states sperm can be retrieved after 65 hours), are the only two documented. In 99.9 percent (of the cases), you cannot find sperm at all after such long hours.
“However, this (Anwar) case is the only one (that I know of) in the world where the sperm can be captured after 56 hours and given to the chemist two days later, where you can still find a good DNA sample,” he said.
He was responding to questions from Ramkarpal Singh during re-examination today.
McDonald had two days ago concurred with suggestions by solicitor-general II Mohd Yusof Zainal Abiden, over the finding in thearticle titled 'Sexual Assault and Semen Persistence' written by GM Willot and JE Ellard.
McDonald said that to his knowledge and according to some journals, you can find a good DNA after the sample was retrieved from the rectum after eight hours.
