On 8 March 2009, Rabidin intruded the home of a 17-year-old schoolgirl Annie Kok Yin Cheng (郭婉晶 Guō Wǎnjīng), raping her before he slit her throat, killing her on the spot.

[2] Between 2013 and 2015, Rabidin was found guilty of killing both Kok and Khairul and sentenced to death, and also received multiple jail terms with caning for some other offences he committed prior to his arrest.

[6] On the early morning of 8 March 2009, at Kampung Ketari in Bentong, a teenage girl was found murdered in her home due to a possible robbery-murder bid.

According to her stepfather, his stepdaughter was a quiet girl who often stayed at home using the computer and liked watching television, and her mother, whose was formerly married once to Kok's real father before her divorce and second marriage, also told police that her daughter's wallet was missing.

[9] The police also found that at least six lighting devices were dismantled in Kok's house, which made them theorizing that the killer was someone known to the deceased, and possibly a premeditated crime.

[10] Following the revelation of Kok's murder, many residents of her kampung in Bentong hyped up security measures by using stronger metal gates and railings to protect themselves from possible intruders.

31-year-old Khairul Hazri bin Jamaludin (1981 – 3 November 2012) and his 28-year-old pregnant wife Yuslailee binti Mat, with whom he was married for three years, were sleeping at the quarters of the forestry department when Rabidin had intruded the place with a home-made shotgun and robbed the couple at gunpoint.

It was suspected that Rabidin, for unspecified motives, had targeted the couple in his killing spree and the police managed to link him to the double murder through investigations.

[17] On 29 May 2012, about five to six months before Rabidin murdered Khairul, a 63-year-old man was robbed at gunpoint at Kampung Kemansur in Bentong, before the man himself, a married father of two, was shot dead by the culprit, who was believed to be Rabidin based on the police investigations that similarly connected him to the fatal shooting, which was Bentong's first case of murder involving firearms to date.

[23][24] After the murder of Khairul Hazri Jamaludin, the public, full of shock over the brutality of the offence and some other previous severe crimes that happened in Bentong, urged the police to quickly investigate and close these cases.

The police also promised the public that they would, to the fullest extent, investigate and solve all these cases to ensure that the killer was brought to justice and conducted a manhunt for the perpetrator.

[27][28] On the same day he was charged, Rabidin pleaded guilty to raping the nine-year-old girl but denied murdering Kok, although his plea of guilt was turned down by the magistrate.

[29] On 18 January 2013, when Rabidin appeared in court once again to undergo preliminary hearings for the existing charges and other crimes he was yet to be charged for, the families of his deceased victims, including Annie Kok's stepfather and mother, the Malay couple's two daughters, nephew and relatives, and the Kampung Kemansur resident's brother-in-law, all appeared in court to catch the first glimpse of the Bentong serial killer, who had been escorted by ten heavily armed policemen for the safety of the members of the public present in the courtroom.

[32] On 5 February 2013, after standing trial at a Sessions Court in Pahang, Rabidin Satir pleaded guilty to four counts of rape and one of committing unnatural sex on four victims aged between nine and 17.

[36] On 30 July 2013, Rabidin, who was then serving his jail term for the previous rape charges, stood trial at the Temerloh High Court for the 2009 rape-murder of Annie Kok Yin Cheng.

[37][38] On 31 March 2014, Rabidin was called to enter his defence after the trial court ruled that the prosecution successfully established a prima facie case against the accused.

He told the court that he was out drinking at a coffeeshop after some night fishing and he was so drunk that he fell asleep on the streets until the next day when a female passer-by woke him up.

[49] The judge also took to mention that the case itself involved the taking of a life, and it also pertained to the safety of women from sexual violence, which required the law's fullest force of deterrence to prevent such a phenomenon from happening again.

Specifically, for the families whose loved ones were murdered, they were disappointed in the government's decision, stating that justice would not be served if the killers who took innocent lives in cold blood were allowed to escape the gallows.

Notably, Tan Siew Ling (陈㛢婈 Chén Xiùlíng), the mother of Annie Kok Yin Cheng, who had been the first of Rabidin's five deceased victims, was among the most vocal of these family members, objecting to the government's plans to remove the death penalty.

A civil group also supported Kok's mother in her plea and provided their research results, which showed that many other members of the public, especially those whose loved ones died due to murder, opposed the repeal of mandatory death sentences.

[77][78] On 9 July 2024, a three-judge bench led by Chief Justice Tengku Maimun Tuan Mat heard Rabidin's appeal at the Federal Court.

In response, the defence lawyer Fairuz Ahmad Yusof submitted that Rabidin was apologetic towards both his victims in these two cases and he insisted there was no intention for him to commit any of the offences in question.

[81] After hearing the submissions, the Federal Court rejected Rabidin's appeal to commute both his death sentences for murdering Annie Kok and Khairul Hazri Jamaludin back in 2009 and 2012 respectively.

[90] Even the residents of Bentong also supported the Federal Court's decision to sentence Rabidin to death, as they sympathized with his victims and despised the harm he caused to countless families back then.
