The police at the moment is still investigating the alleged sodomy case and I belief they don't have sufficient evidence to convict Anwar. They have the video footage taken at the apartment and perhaps some induced witness .They have measured Anwar dick and he was strip naked for the physical examinations but they still cannot prove that an anal penetration actually occurs.
The missing piece to complete their jigsaw puzzle is Anwar DNA. DNA forensic technology will be able to prove that the sodomy actually occurs or not. To do that they need the victim DNA and also the accused DNA coupled with bodily fluid taken from Saiful anus. The fluid or anal swab of the victim should consist of the victim and also accused DNA fraction. The key portion of the autoradiograph probe analysis of various DNA samples in a rape investigation is shown in the figure below. Couldn't find a sodomy sample and rape is the closes sample we can use to describe the DNA forensic technology.
DNA evidence is most powerful when used to demonstrate that an individual is not the source of biological evidence in a criminal investigation. In the case of a rape, if the male fraction of the DNA evidence contains alleles that are not shared with the suspect, then the suspect could not have deposited that sperm. The suspect would be excluded as a possible source of the DNA found during the sexual assault exam.
Notice that in this set of evidence, the victim's DNA profile serves as an internal control. The victim's known blood sample (lane 1) should, and does, match the female fraction of the DNA from the sex assault exam (lane 4).
In contrast, the defendant's known blood sample (in lane 2) does not match the male fraction of the evidentiary DNA (in lane 5). All it takes to exclude a defendant is a single band in the evidentiary lane that is not found in the defendant's lane. In this case, the defendant does not have the top band in lane 5, thus he could not have been the source of the DNA in lane 5.
Now if the police don't have Anwar blood and DNA sample to mix with Saiful's ,they wouldn't have a solid or concrete evidence to nail Anwar,that is on the assumption that the police are fabricating evidence to charge Anwar.
Coincidentally ,at the parliament,Khairy suggested that Anwar should give his DNA voluntarily when Anwar ,his lawyers and Azizah didn't even know about it yet. How is it that Khairy knows the police needs Anwar DNA in advance ? Is he part of the gang that conspire to topple Anwar?
Anwar should be careful that his DNA is not taken from him at all cost as it could be the single most important evidence that will send him to jail for a long time.
Lastly.I'm no expert in DNA forensic and I'm just simply gathering what I can from the internet and try to join all the pieces together. For better confirmation please consult an expert in this area.
