# investigation

On January 26, 2015, after committing his tenth crime at around 8:00 AM in Lan Tak Fa Subdistrict, Nakhon Chai Si District, Police Lieutenant General Sophon Phisutthiwan revealed, after inspecting the crime scene, that the suspect's modus operandi was similar to that of a serial burglary in several areas. This was the tenth reported case. The modus operandi was consistent: the crimes occurred late at night, targeting elderly victims living alone. The suspect used tools to pry open windows or doors to break into the house and steal property. In every crime, the suspect never took the victims' communication devices. Some victims were raped or assaulted. After the crime, the suspect fled the scene. Police are confident that the suspect arrived by waterway. Victims described the suspect's physical appearance as matching those of other victims. However, fingerprint analysis of the suspect did not match any records in the criminal registry.

On January 27, police released an update on the case, stating that the suspect acted alone, breaking into houses through windows between approximately 1:00 AM and 3:00 AM. The suspect was barefoot and left clear fingerprints and footprints in all cases. Police General Chakthip Chaijinda stated that the suspect may still be in the Samut Sakhon or Samut Songkhram provinces, or possibly the Nakhon Chai Si district, as they are unaware that they are being monitored or pursued by the police.

On January 28, Police Lieutenant General Sophon Phisutthiwan and Police General Worapong Chiupreecha traveled to the scene of the crime in case number 10 to inspect the location and any traces left by the perpetrator. An examination of the canal adjacent to the house suggests that the perpetrator may have dumped poisoned food into the canal, resulting in a large number of fish deaths.

On January 29, police confirmed that DNA tests in all 10 rape cases revealed the same DNA. However, DNA tests of at least 300 suspects since 2010 did not match the perpetrator's DNA. Police Colonel Worapong Chiwpreecha further revealed that in case number 9, which occurred on December 25, 2014, the victim remembered the perpetrator wearing a dark blue long-sleeved crewneck t-shirt with the word "Prasert" embroidered in yellow on the left chest. Five to six other victims also confirmed that the perpetrator wore a similar long-sleeved shirt.

On February 2, Police Lieutenant General Sophon Phisutthiwan assigned the Nakhon Pathom Provincial Police investigation team to expand the search area from Nakhon Chai Si, Sam Phran, Phutthamonthon, and Bang Len districts to include Mueang Nakhon Pathom and Kamphaeng Saen districts. The additional occupational groups to be investigated were coconut farmers and sawmill workers. This investigation was necessary because sawdust and coconut fibers were found clinging to the cartoon-patterned shorts of the suspect recovered from the crime scene in case number 9.

On February 3rd, forensic investigators examined the type of chemical found in the poisoned dogs and fish in the canal next to the house. It was identified as a carbonate herbicide, which takes 2-3 hours to take effect after being ingested by the dogs. Police suspect the perpetrator waited for the poison to take effect before committing the crime. The fish died in the canal likely because the perpetrator mixed the poison with food but didn't use it all, then threw the leftover food into the canal, causing the fish to die.

Police observed that the suspect committed the crimes during weekends, specifically Fridays, Saturdays, and Sundays. Their targets were women aged 50 and older, described as fair-skinned and overweight, living alone in detached houses far from residential areas. The suspect acted alone, poisoning dogs if the victim's house had one, and only stole money and gold.

The suspect is believed to have resided near a river or canal, no more than 5 kilometers from the scene of the crime.

According to the police sketch, the suspect is a Thai male, 170 centimeters tall, with a muscular build and six-pack abs.

All victims stated that the perpetrator had no body odor, leading them to believe that the perpetrator likely showered before committing each crime.

# Suspect

# Mr. Kai (pseudonym)

On February 25, 2015, officers from the Investigation Division of Provincial Police Region 7, along with Nakhon Pathom Provincial Police, arrested a 35-year-old man named Kai (pseudonym) at an ice factory in Phimai District, Nakhon Ratchasima Province. He resembled the sketch of the suspect and was a former employee of the Nakhon Pathom Highway Department. Kai confessed to being the perpetrator of a series of murders and rapes of elderly women. Police then took Kai for a DNA test. At 2:00 AM the following day, the Commander of the Forensic Science Office stated that Kai's DNA did not match the samples collected from the crime scenes, and he was released.

# Paitoon Pui-ngern(ไพฑูรย์ ปุยเงิน)

On August 27, 2015, police arrested Paitoon Pui-ngern, 32, for assaulting and attempting to rape an 81-year-old woman in Talat Mai Subdistrict, Wiset Chai Chan District, Ang Thong Province.

Paitoon denied raping her, but police have enough evidence and witnesses to convict him. Police also suspect that Paitoon's behavior and appearance resemble those of a perpetrator in a series of 10 murder and rape cases. Furthermore, Paitoon had worked in Samut Sakhon and Samut Songkhram provinces during the time the murders and rapes occurred. Therefore, police had forensic officers conduct a DNA test on him, but it did not match the DNA of the perpetrators in the serial murder and rape cases.

# Suprachai Noonoi(สุพรชัย หนูน้อย)

On July 19, 2017, police arrested Suprachai Noonoi, also known as Paek Pakwan, for the murder and rape of a 14-year-old girl on July 13, 2017, in her home in Tambon Sib Et Sok, Ban Pho District, Chachoengsao Province. He was arrested after his DNA matched semen found on the victim's clothing. Suprachai had previously served a prison sentence for drug possession in Khon Kaen Province in 2015. Prior to this murder, he had committed three rape cases in Khon Kaen and Chonburi provinces. Police Region 7 suspected Suprachai might be the perpetrator of a series of murders and rapes in Nakhon Pathom, Samut Sakhon, and Samut Songkhram provinces over the past 2-6 years, and collected DNA samples from him to compare with the perpetrators of the serial murders and rapes. However, the DNA test results did not match.

# Mr. La-ong Khaophan(ละออง ขาวพันธุ์)

On July 27, 2022, police arrested La-ong Khaophan, 66, in Sam Chuk District, Suphan Buri Province, for the rape and murder of 72-year-old Sali. The murder occurred on the night of July 26, 2022, at her home in Tambon Nang Buach, Derm Bang Nang Buach District, Suphan Buri Province. Police found similarities between La-ong's actions and a series of murders and rapes of elderly women that had occurred seven years prior. La-ong had previously worked as an employee at a fish processing plant in Samut Sakhon Province before being arrested for attempted indecent assault in 2012. He served seven years in prison and was released in May 2020. He was then imprisoned again for eight months for burglary in 2021. Police conducted a DNA test, which did not match that of the perpetrator in the serial murders and rapes of elderly women, but he was still prosecuted for the murder of Sali.
