On 30 August 2010, in Banting, Selangor, Malaysia, 47-year-old cosmetics millionaire Datuk Sosilawati Lawiya and her three companions – bank officer Noorhisham Mohamad, lawyer Ahmad Kamil Abdul Karim, and her driver Kamaruddin Shamsuddin – all went missing. The four missing people were later found to have been murdered and had their bodies burnt by a lawyer named N. Pathmanabhan and another three accomplices. The remains of Sosilawati and the three men were later found at a farm in Tanjung Sepat, which belonged to Pathmanabhan. Pathmanabhan and his three farm hands – T. Thilaiyalagan, R. Matan and R. Kathavarayan (also spelt R. Khatavarayan) – were all arrested and charged with murder based on circumstantial evidence and without the bodies of the victims in this case.

In May 2013, the four accused were all convicted of murder and sentenced to death by the Shah Alam High Court. A long-drawn appeal process ended in March 2017, with the Federal Court confirming the death sentences of Pathmanabhan, Thilaiyagan, and Kathavarayan but released Matan after citing insufficient evidence to link him to the murders. The condemned trio - Pathmanabhan, Thilaiyagan and Kathavarayan - are still incarcerated on death row as of 2024.

The conviction of the killers marked the second case of murder conviction(s) without a body in Malaysia after the 1963 case of Sunny Ang, a law student who was hanged for murdering his girlfriend during a scuba diving trip for her insurance at Sisters' Islands in Singapore, when Singapore was still a part of Malaysia back then.

Murder investigation

On 30 August 2010, in Selangor, Malaysia, 47-year-old cosmetics millionaire Datuk Sosilawati Lawiya and her three companions – 38-year-old bank officer Noorhisham Mohamad, 32-year-old lawyer Ahmad Kamil Abdul Karim, and her 44-year-old driver Kamaruddin Shamsuddin – went to Banting from Kuala Lumpur for business matters, and they went missing thereafter. At the time of her disappearance, Sosilawati, who was of Indonesian descent and grew up in Johor, was the founder of Nouvelle Beauty Center Sdn. Bhd since the 1990s, and after her first marriage (which ended with a divorce), she was married to Malaysian rock singer Nashrudin Elias (nicknamed "Nash") on 16 November 2006 before her divorce in 2009 and third marriage, and she also had six children.

When Sosilawati and the three men did not return home that day, a missing persons report was lodged, and the families of the missing four went to search for them. The police took over the case and a week later, the police found the cars of Sosilawati and Ahmad Kamil parked at an apartment and a five-star hotel respectively in Subang Jaya. The investigation officers managed to uncover through their investigations that Sosilawati and the men were supposed to meet two lawyers – 41-year-old N. Pathmanabhan (Pathmanabhan a/l Nalliannen) and his 38-year-old brother Surendren – over a land deal. The brothers were questioned ten days after the disappearance of the millionaire and her partners, and six farm workers, who were employed at Pathmanabhan's betel leaf-cum-vegetable farm in Tanjung Sepat, were also detained for questioning.

After thorough investigations, it was uncovered that Pathmanabhan was the mastermind of the murders and due to a land deal allegedly going sour, he had solicited the three farmhands to kill Sosilawati and the three men, while Surendren himself was not involved in the murders. Regardless, given their unrelated previous acts of professional misconduct as lawyers, both Pathmanabhan and Surendren were no longer allowed to practice law through a hearing in October 2010. A month after murdering Sosilawati and her associates, on 13 October 2010, Pathmanabhan and the three farmhands - 20-year-old T. Thilaiyalagan (Thilaiyallagan a/l Thanasagaran), 21-year-old R. Matan (Matan a/l Ravichandran) and 31-year-old R. Kathavarayan (Kathavarayan a/l Rajodorai) - were officially charged with four counts of murder. Pathmanabhan was also named a prime suspect behind the disappearances of several people who were formerly his clients, including an Indian businessman, and it was speculated that Pathmanabhan had killed these people as well, making it a total of 13 murder cases which Pathmanabhan was allegedly responsible for.

It was believed that the bodies of Sosilawati and the others were being burnt to ashes before they were thrown into a nearby river. A police search was conducted within the perimeters of the farm, and the police managed to recover multiple exhibits of evidence, including bone fragments, blood stains and torn pieces of an underwear, and also discovered an alleged makeshift burning site where the four murder suspects had allegedly burnt the bodies after killing Sosilawati and her men. In total, 2,030 specimens of burnt human bones and teeth were retrieved from the river inside the farm, and several of the four victims' personal belongings, including Sosilawati's wristwatch, were also recovered.

Two other workers - 19-year-old K. Sarawanan and 26-year-old U. Suresh were also charged, not for murder but for seven counts of aiding the four alleged killers to dispose of the evidence under Section 201 of the Penal Code. In October 2010, the pair was sentenced to seven years in prison after they pleaded guilty. Four months later in February 2011, the duo's jail terms were enhanced to 20 years of jail each by the Shah Alam High Court.

Murder trial and sentencing Prosecution's case

On 4 July 2011, the four conspirators of the Banting murders – N. Pathmanabhan, T. Thilaiyalagan, R. Kathavarayan and R. Matan – officially stood trial for the murders of the four victims – Sosilawati Lawiya, Noorhisham Mohamad, Ahmad Kamil Abdul Karim and Kamaruddin Shamsuddin – at the Shah Alam High Court.

The trial court was told that Pathmanabhan and Sosilawati had dealings with each other with regards to land transactions in Penang, and on the day of the murders, Sosilawati and the three men arrived at the farm to meet with Pathmanabhan over a pending land deal. It was found that this was a ruse by Pathmanabhan, who was unable to help Sosilawati to honor a cheque pertaining to the land matters in Penang, and hence he lured Sosilawati and her partners to the farm, where he and his co-defendants held them hostage upon their arrival. It was the prosecution's case that due to his failure to settle the cheques, Pathmanabhan directed the three farmhands to murder Sosilawati and the three men. Under Pathmanabhan's order, the trio – Thilaiyalagan, Kathavarayan and Matan – had battered the victims to death with a cricket bat and other weapons, and they placed the bodies on a makeshift pyre and burned it down to ashes. The conspirators disposed of the ashes at the nearby river within the perimeters of the farm. The four victims' presence at the farm was corroborated by the testimony of Indonesian maid Siti Hamidah Karnax, who had seen a woman and three men entering the farm and a huge fire coming from the farm, and also heard a woman screaming at least twice from the farm.

The blood of the three male victims was found on the wall, and a cricket bat and two pieces of zinc recovered from the farm also contained the DNA stains belonging to the victims. The two other accomplices, U Suresh and K Sarawanan, who were serving their sentences at Sungai Udang Prison, Melaka for helping to dispose of the evidence, came to court as prosecution witnesses. 39-year-old Suzana Radin Pangat, the wife of Noorhisham Mohamad (who was one of the four murdered), stated that she received a phonecall from her husband, who told her he would be absent from home for three days and would help Sosilawati with the land dealings; but, as it turned out, Noorhisham was in fact threatened by the killers to make this call to his wife to distract her and the families of the other victims, before he was murdered. Suzana was initially angry that her husband would leave her and their children to help settle Sosilawati's matters before she realized the sad truth of her husband's brutal death. The original farm owner's nephew K. Sree Ganashan also testified that his aunt had sold the farm to Pathmanabhan a year before the murders. 62-year-old Buhari Mohamed, who was Sosilawati's ex-husband from her first marriage, also testified that when he noticed that his ex-wife was missing, he contacted Pathmanabhan and asked why Sosilawati had not yet returned home after going to Banting, wanting the ex-lawyer to take responsibility. Pathmanabhan reportedly replied that he did not know and seemed surprised why would a good person like Sosilawati disappear.

Defence's case

At the close of the prosecution's case, the trial court ruled that the four accused had a case to answer and ordered the four to enter their defence in April 2012. Pathmanabhan was the first to take the stand. Pathmanabhan denied planning to kill Sosilawati and three others, and also denied that the land sale and purchase deal in Penang involving the cosmetics millionaire was a fraud. During the trial, Pathmanabhan also testified about his involvement in two conflicting land deals and was entangled between Sosilawati, a prominent entrepreneur, and Datuk Abdul Rahman Palil, described by Pathmanabhan as a powerful politician, and as this was an ethical breach and it compromised his impartiality, Pathmanabhan admitted to his reluctance to arrange a meeting involving both parties. The judge would later consider this in his verdict as a starting point for Pathmanabhan to commit the murder of Sosilawati and her associates after choosing between the two.

The three farm workers also elected to put up their defence. Thilaiyalagan's defence lawyer Gurbachan Singh argued that his client never met Sosilawati and the three men, and Thilaiyalagan insisted that he was never involved in the murders. Matan similarly protested his innocence, stating that he had no reason to murder Sosilawati and had never met any of the victims on the day in question. Matan stated that he never received any order from whoever to commit a crime, much less murder. Kathavarayan, who also denied killing the four, stated that he only acted to apprehend the driver at the time of the incident and pinned the blame on the others, and he denied during cross-examination that he was harbouring vengeance against Pathmanabhan over him driving his family out of their house. Kathavarayan also testified that he heard Pathmanabhan told him not to tell anyone about the murders and he would hang himself if any trouble arose. In response, the prosecution argued that the defence of the four men should not be accepted, stating that their evidence was unsafe and unreliable, and they should be convicted as charged.

Verdict On 23 May 2013, Justice Datuk Akhtar Tahir of the Shah Alam High Court delivered his verdict. In his judgement, Justice Akhtar found that the primary motive behind Sosilawati's murder was related to land issues. Justice Akhtar found that Pathmanabhan had a motive to kill Sosilawati due to his inability to honor a cheque issued to her and also directed the other three defendants to murder the four. The judge also noted that in the matter of Pathmanabhan being caught between Sosilawati and the politician, when pushed to the edge, Pathmanabhan resorted to the drastic step of eliminating Sosilawati after choosing between the two, which inadvertently led to the deaths of Noorhisham, Kamaruddin and Ahmad Kamil, who were merely at the "wrong place at the wrong time".
