A Chinese New Year greeting mistakenly sent to a former lover led to the death of Mr Dexmon Chua.
Months later, his decomposed body was found abandoned in a military live firing area near Lim Chu Kang Road.
For his part in the grisly revenge killing, former town council cleaning supervisor Chua Leong Aik, 66, was yesterday jailed five years.
He had earlier pleaded guilty in the High Court to one charge of voluntarily causing grievous hurt and one charge of abduction.
Mr Dexmon Chua, 37, was working as a materials analyst for Tetra Pak when he got to know Madam Serene Goh, now 49, in 2003.
She is married to Chia Kee Chen, 55, and lives in Choa Chu Kang Avenue 2. Mr Dexmon lived nearby at Choa Chu Kang Avenue 4, so he and Madam Goh often took the company transport together.
Mr Dexmon and Madam Goh became close in July 2011 and started an affair the following month, carrying out their trysts in his car after work.
But this came to an end a year later, when they started quarrelling more often. They still communicated over the phone.
Later that year, Chia found romantic messages on his wife's phone and confronted her.
She admitted to the affair and said there were videos and pictures of her having sex with Mr Dexmon, which she feared he would spread.
Upset, Chia called Mr Dexmon using Madam Goh's mobile phone and scolded him in Hokkien, telling him to end the relationship and threatening to beat him up if they resumed their fling.
Some time after that, when Chia picked up his wife from work, she pointed out her former lover to him.
On Feb 9, 2013, Mr Dexmon sent a video with a Chinese New Year greeting to Madam Goh over WhatsApp, followed by another message apologising for sending the video by mistake.
But Chia saw the messages and confronted his wife, who insisted the affair was over.
About two months later, Mr Dexmon told his sister that he felt he was being stalked by a driver in a Hyundai car who would often be staring at him as he drove past him at work.
He sometimes saw the same car parked below his block, with the driver staring at their flat.
Mr Dexmon made two police reports.
The first was in December 2012, in which said he had been receiving vulgar and threatening calls and messages from a particular phone number.
The second was in July 2013, when he said that a dark purple Hyundai car had been parked below his block, and its driver staring at his flat.
Police investigations showed that the threatening calls came from a prepaid mobile phone line under Chua's name that was used by Chia. The two men were old friends.
The dark purple Hyundai belonged to Chia's nephew, but Chia often borrowed it.
Chia owned a fish farm in Tanjung Pinang, Indonesia, which was run by an Indonesian man, Febri Irwansyah Djatmiko.
On Dec 24, 2013, Chia told Febri that he was needed in Singapore to help kill someone who had raped his wife and that if it was successful, Chia would set up a business for him in Tanjung Pinang.
Febri agreed and entered Singapore on Dec 26, 2013.
The next day, Chia and Febri went to the substation beside Choa Chu Kang Avenue 4 where Chua was staying.
It was at the substation (above) that they planned the revenge. They would accost Mr Dexmon in a carpark, blocking his way so he would be trapped.
Chia and Febri would lie in wait to pull him into the back of a van, where they would knock him out and beat him up.
When it was agreed upon, Chia called up a friend to borrow a van.
On Dec 28, at about 9.30pm, Chia went to the substation with two knives, an electrode, a torch and a packet of plastic gloves.
The three men drove to the multi-storey carpark at Block 429A, Choa Chu Kang Avenue 4 and waited for Mr Dexmon, who appeared three hours later, at about 1am.
He parked right next to the van.
As he got out to go to the back of his car, the men rushed out of the van and blocked him, trapping him between the vehicles.
Chia asked Mr Dexmon if he could recognise him, but before he could respond, punches him in the face. The three men then beat him up in the first of two savage attacks.
They eventually pushed him into the van through the side door. There, he was electrocuted and passes out.
Chia and Febri tied up their victim's hands and feet while Chua drove towards Lim Chu Kang. During the journey, Chia and Febri continued to beat the victim, hitting him with a hammer-like object.
As he drove, Chua could hear the attack and their captive's moans. There was also a strong stench of blood. The attack was so brutal that it left bloodstains all over the back of the van, including the ceiling.
After a while, Chua stopped the vehicle around Lim Chu Kang, saying he could not take it any more and he got out of the van.
He took a bus back to the substation.
Chia took over the wheel and drove towards the military live firing area off Lim Chu Kang Road.
He and Febri carried Mr Dexmon's lifeless body out of the van and dumped it among the overgrowth in the live firing area.
Later that day, the men left for Malaysia together with Chia's wife and two daughters.
From there, Febri fled to Indonesia while Chia and his family returned to Singapore on Dec 31, 2013. He was then arrested by police. Febri remains at large.
Chia led investigators to Mr Dexmon Chua's badly decomposed body on Jan 1, 2014.
Chua was arrested eight days later.
In mitigation, defence lawyer James Ow Yong said Chua has two young children, aged two and seven, with his second wife and the family is in Indonesia.
He had misplaced his trust in his friend and played a minimal role in the attack.
Justice Kan Ting Chiu noted that he was neither mastermind nor instigator in the attack.
When sentencing Chua to five years' jail, he said: "While not the instigator, the facts show that you have done nothing to stop the assault.
"There was no sign of remorse or compassion and we now know that even when you were called up by the police, you had initially denied knowledge or involvement."
