Mona Koh was a Singaporean nightclub hostess manager, or “mamasan”, who worked in Singapore’s nightlife entertainment industry from 1970. In later retrospective media coverage and online discussion, she was referred to as the “Queen of the Nightclubs”. She is best known for surviving a shooting in October 1994 at Katong People’s Complex that left her permanently paralysed from the waist down, a case that has never been solved.<ref name=":0">Fasaisirinan, Thanawut. “[https://mustsharenews.com/mona-koh-shooting/ MS Unsolved: The cold-blooded shooting of ‘mamasan’ Mona Koh at Katong in 1994]”.

Accessed 17 July 2026.</ref> Koh reportedly continued working in the nightclub industry for years afterwards despite her disability, and her case has resurfaced periodically in Singapore media and online true-crime discussion as one of the country’s most enduring unsolved shootings.<ref name=":0" />

She was reported to have died in July 2026 at the age of 80, an event that circulated through social media and community forums and prompted renewed public reminiscence about her and about Singapore’s now-vanished nightclub scene of the late twentieth century.

==What is Mona Koh's background?==
Koh was reported to be of Indonesian descent and began working as a nightclub hostess in Singapore in 1970, in her early twenties.<ref name=":0" /> Within about a decade she had risen to become a mamasan, a term used in Singapore and elsewhere in Southeast Asia for a woman who manages the hostesses at a nightclub or karaoke lounge, organising their schedules and introducing them to guests. Mamasans were a fixture of Singapore’s nightlife industry from the 1970s through the 1990s, and the more established among them held considerable sway with club owners, hostesses and clientele alike.

By the early 1980s, Koh was regarded as one of the longest-reigning mamasans in what was described as a “high-turnover industry”, a reputation that later coverage distilled into the nickname “Queen of the Nightclubs”.<ref name=":0" />

Part of her standing in the trade rested on her role connecting the hostesses under her charge with some of Singapore’s wealthiest businessmen. Media accounts reported that by 1994 she was earning more than S$15,000 a month, a substantial sum at the time. She was also known to gamble frequently, both at the Singapore Turf Club and aboard casino cruise ships operating out of Singapore.<ref name=":0" />

==The 1994 Katong shooting==
On the evening of 15 October 1994, at around 7.40pm, Koh was waiting in the ground-floor lift lobby of Katong People’s Complex, a shopping centre in the Katong area of eastern Singapore, when an unidentified gunman approached and fired two shots at her from a .38 calibre Smith & Wesson revolver.<ref name=":0" /><ref name=":1">Tay, Boon Chuan. "[https://eresources.nlb.gov.sg/newspapers/digitised/page/newpaper19941103-1.1.14 Mamasan calls for facial]". ''NewspaperSG, National Library Board Singapore''. Digitised issue, October 17, 1994. Accessed 17 July 2026.</ref>

One bullet struck her face; the second hit her back. The assailant, described by witnesses as a slim, dark-complexioned Chinese man with short hair, fled the scene through a side exit and was never caught.<ref name=":0" />

Despite her injuries, Koh remained conscious and was rushed to Singapore General Hospital, where she underwent emergency surgery. Surgeons removed the bullet lodged in her face, but the second bullet had shattered her spine and the damage could not be reversed, leaving her paralysed from the waist down. She remained in hospital for 40 days, during which police stationed guards outside her room and screened her visitors, before she was discharged permanently wheelchair-bound.<ref name=":0" /><ref name=":1" />

Katong People’s Complex, the site of the shooting, no longer exists. The building was subsequently redeveloped, first into Katong Mall and later into the current i12 Katong shopping centre.<ref name=":0" />

===Mona Koh 1994 Katong shooting investigation theories===
Investigators ruled out robbery as a motive after establishing that Koh’s handbag, which contained about S$3,000 in cash, had been left untouched at the scene. Koh herself told reporters at the time that she did not recognise her attacker and could not think of anyone who would want her dead.<ref name=":0" />

Police and media reports at the time raised several possible motives, none of which was ever confirmed. These included the theory that a rival mamasan may have wanted her removed as competition, given her seniority and dominance in the trade, and the theory that the shooting was connected to unpaid gambling debts, given her frequent visits to the Turf Club and shipboard casinos. A further theory pointed to a broader dispute connected to the nightclub industry’s less visible dealings.<ref name=":0" /> None of these theories has been substantiated, no suspect has ever been identified or charged, and the case remains unsolved more than three decades on.

The shooting was extensively reported at the time by The Straits Times and The New Paper, and was revisited by The New Paper in February 2006 and by The Straits Times in May 2010 as part of retrospective coverage of unsolved Singapore crimes.<ref name=":0" /><ref name=":1" />

===Later life and death===
As of the 2010 Straits Times retrospective, Koh, then reportedly 62 years old, was said to still be working as a mamasan despite her disability. She lived with the second bullet permanently lodged between her spine and liver, which could not be safely removed, and required daily medication to manage chronic pain from the injury.<ref name=":0" />

Koh was reported to have died on 15 July 2026 at the age of 80. News of her death first circulated through a memorial post on the Facebook page “Death Kopitiam Singapore”, which referred to her by the fuller name Mona Koh See Tiang (許絲珍) and credited photography to a studio called “Beautiful Memories”.<ref>Tan, Constance.
