The Beginning of the Case

The serial murder case that was carried out by Rian shocked the public in March 2021. The disclosure of the serial murder case began when the bodies of two women were found in Bogor City at different times. One body was found bound in a plastic bag in the Tanah Sareal area, on the edge of Jalan Raya Cilebut, Bogor City on February 25, 2021. Based on the results of the Bogor Police autopsy, a blunt force wound was found on the woman's neck which was later found to have the initials DP (18) . Two weeks after the discovery of DP's body, the Police arrested Rian who was suspected of killing DP.[1]

"We found out about this case after we conducted a long investigation for about two weeks. Collecting witnesses of up to 15 people, both relatives and colleagues, including key witnesses who pointed to the perpetrators," said Bogor Police Chief Kombes Pol Susatyo Purnomo Condro in a press conference, 11 March 2021.[2]

The Police found other facts during Rian's investigation. About two weeks after killing DP, Rian is also known to have killed a woman with the initials EL (23). EL's body was found on the side of the road in Pasir Angin Village, Megamendung, Bogor Regency on March 10 2021. Based on the autopsy results, blood spots were found in the mouth of a resident of Caringin District, Bogor.[3]

Murder Mode And Pattern

Rian uses the same modes and patterns when carrying out his actions. He chose his victims at random by getting to know them on Facebook social media. Then, Rian took his victim on a date in Puncak, Bogor Regency, with the lure of IDR. 1 million. After having a date at the hotel, Rian would kill the victim by strangling her and taking her property.[4]

Not only were the modes and patterns of the killings similar, Rian also chose the same hotel when killing the two victims. After killing, Rian put the victim's body in a large backpack to be disposed of. Susatyo said Rian was conscious when he killed the two victims. Based on other findings, there is a possibility that Rian will date other women and kill in the same way.[5]

"Based on the results of interrogation, the suspect may not be deterred from committing the first murder and the suspect enjoys the second murder. Currently we are still developing, including tracing the digital footprint of the suspect," said Susatyo. Therefore, during a psychiatric examination, the Police concluded that Rian was behaving like a psychopath or serial killer in a serial killer film.[6]

Sentenced to 13 Years in Prison

Muhamad Rian bin Mamad (21), the perpetrator of the serial killings of 2 women from Bogor was found guilty and sentenced to 13 years in prison by the Cibinong District Court. This sentence is 1 year lighter than the prosecutor's demand, which is 14 years in prison. "Muhamad Rian has been sentenced to 13 years in prison, because he was proven guilty of committing the crime of murder as stated in Article 338 of the Criminal Code," said Public Relations of Cibinong District Court Amran S Herman, Tuesday (23/11/2021).[7]

Quoted from the website of the Cibinong District Court (PN), Bogor Regency, the verdict against Rian was decided on Tuesday (5/10/2021). The decision was knocked out by a judge chaired by Christina Manulang along with 2 member judges Yulinda Trimurti Asih Muryati and Siti Suryani Hasanah.[8]

In addition, the panel of judges also decided to seize evidence related to Rian's case to be destroyed. The evidence is in the form of 9 pieces of IDR. 100 thousand & 1 IDR 50 thousand cash, 5 black polybags, 1 blue skirt with blood stains, pink bra with cut straps, 1 white shirt, 1 jeans, 1 blue shirt with white stripes and 1 mountain bag.[9] Creepy.
