How come there's No evidence of sodomy?

Doctor: No evidence of sodomy

There is no evidence that Mohd Saiful Bukhari Azlan was sodomised, according to the doctor who examined him four hours before he lodged a police report alleging he was sexually assaulted by PKR leader Anwar Ibrahim.

It is believed that Saiful went to two different hospitals on June 28 - the day he lodged the police report claiming that he was sodomised by his ex-boss.

He first went to Hospital Pusrawi (Pusat Rawatan Islam) in Jalan Tun Razak - a government-linked Islamic medical institution - at about 2pm.

According to a copy of the medical report obtained by malaysiakini yesterday, Saiful went to the hospital complaining of 'tenesmus' - a medical term for difficulty and pain in passing motion.

He was examined by Dr Mohamed Osman Abdul Hamid, the medical officer on duty.

The doctor said that the patient had alleged he was assaulted by the intrusion of a piece of "plastic" in the anus.

Mohamed Osman, according to his medical report which was recorded at 2.14pm, found "zero active bleeding", "zero ulcer or pus", "zero tear and scar" in Saiful's anus.

He also stated that Saiful appeared "alert", "comfortable", "not pale" and did not show any fever symptoms.

A senior Pusrawi official told malaysiakini this morning that the hospital had launched an internal investigation on how Saiful's medical report was leaked.

When malaysiakini showed him a copy of the report, he refused to return it saying, "It's our document."

Mohamed Osman, in his report's concluding remarks, advised Saiful to go to a government hospital so as "to rule out" assault and sodomy.

At 6pm on that day, Saiful went to Hospital Kuala Lumpur for his second medical examination. He subsequently lodged a report against Anwar at the police beat at the hospital.

According to an expert who has dealt with rape and sodomy cases, the victim must provide a second medical examination in a government hospital.

She said the court will only accept evidence from a government hospital but the first medical examination must collaborate with the second report, otherwise this could be challenged during the trial.

"From the report, the doctor had failed to find any evidence to support the patient's complaint. That was why he asked the patient to go to a government hospital to conclusively rule out assault or sodomy," said the expert who requested anonymity.

The doctor was said to be under tremendous stress as a result of the police interrogation and was advised by the hospital to take leave.

A check at the emergency unit where Mohamed Osman is attached revealed that he has taken leave since last week.

Apparently, it was reported at Malaysia-Today's blog that the medical doctor was lockup for 3 days by the police for "interrogation purpose".

Raja Petra's Malaysia-Today alleged that the doctor was directed to re-write his medical report to affirm that there were something that can relate the anus trespassing but the doctor refused to write a new daVinci Code.

The police then picked up the doctor and detained him for three days. As much as they tried to force him to change his report to implicate Anwar he refused to do so.

Until today, the doctor stands by his report ... He knows he is going to be made to pay for this but he doesn’t care. He is not going to change his report ...

... he [Dr Mohamed Osman Abdul Hamid] has now taken his entire family and has gone into hiding because the police are looking for him and they want him to change his medical report.

Analytical Dissertation

Maybe, this is the reason that the police need some new DNA samples which the old samples cannot do. However, Prime Minister Pak Lah said the old DNA samples from Anwar had expired and thus a new sample is needed to collaborate and demystify.

Some people said this new scientific findings was discovered when our scientist conducted various tests at the International Space Station of which the results of the tests indicate that there is a high probability that DNA samples can expire over time if not properly utilized and stored.

However, the American and Russian scientists have yet to concur with the research findings and thus they could not confirm this hypothesis neither could they dispute the validity.

It is sad to note that American and Russian scientists have slackened and are far behind our Malaysian scientists in their medical research. We hope that the Americans will work hard to catch up with our progress; otherwise, they will face a drop in their International Rating and may rank below us.

Faking DNA evidence: Case Study

Dr. John Schneeberger (born 1961) is a former Canadian physician, who drugged and raped one of his female patients and his stepdaughter. For years, he was able to evade arrest by planting a fake DNA sample inside his own body, thus successfully foiling DNA tests.

On the night of 31 October 1992, Schneeberger sedated his 23-year-old patient, Candice, and raped her. While Versed — the anesthetic he used — has strong amnesiac effect, Candice was still able to remember the rape. She reported the crime to the police.

Scheenburger's blood sample was, however, found not to match the samples of the alleged rapist's semen, thus clearing him of suspicion. In 1993, at the victim's request, the test was repeated, but the result was negative, as well. In 1994, the case was closed.

Candice, still convinced that her reminiscences were true, hired Larry O'Brien, a private detective, to investigate the case. He broke into Schneeberger's car and obtained another DNA sample, which, this time, matched the semen on victim's panties and pants. As a result, third official test was organized. The obtained blood sample was, however, found to be too small and of too poor quality to be useful for analysis.

In 1997, Lisa Schneeberger found out that her husband had repeatedly drugged and raped her 15-year-old daughter from her first marriage. She reported him to the police, which ordered fourth DNA test. This time, multiple samples were taken: blood, mouth swab, and hair follicle. All three matched the rapist's semen.

During his 1999 trial, Schneeberger revealed the method he used to foil the DNA tests. He implanted a 15 cm Penrose drain filled with another man's blood and anticoagulants in his arm. During tests, he tricked the laboratory technician to obtain blood sample from the place the tube was planted.

He was found guilty of sexual assault, of administering a noxious substance, and of obstruction of justice, and received a six-year prison sentence.

The value of DNA evidence has to be seen in light of recent cases where criminals planted fake DNA samples at crime scenes. In the case above, Dr John Schneeberger planted fake DNA evidence in his own body: Dr. Schneeberger raped his sedated patients and left semen on her underwear. Police drew Schneeberger's blood and compared its DNA against the crime scene semen DNA on three occasions, never showing a match. It turned out that he had surgically inserted a Penrose drain into his arm and filled it with foreign blood and anticoagulants.

A Penrose drain is a surgical device placed in a wound to drain fluid. It consists of a soft rubber tube placed in a wound area to prevent the build up of fluid.

A Penrose drain removes fluid from a wound area. Frequently it is put in place by a surgeon after a procedure is complete to prevent the area from accumulating fluid, such as blood, which could serve as a medium for bacteria to grow in.

An anticoagulant is a substance that prevents coagulation; that is, it stops blood from clotting. A group of pharmaceuticals called anticoagulants can be used in vivo as a medication for thrombotic disorders.

Anticoagulants are given to people to stop thrombosis (blood clotting inappropriately in the blood vessels).
