Sun Punchaat – My sister-in-law killed my mother-in-law for money

I have often heard the saying that to care for those who once cared for us is the highest honour. It is meant to be one of life’s greatest duties, a way of repaying the sacrifices of those who raised us. Yet the times we live in tell a far darker story. Increasingly, we hear of cases where the elderly are not treated with dignity, but rather with cruelty and neglect at the hands of those entrusted to protect them.

Just last week, a wave of shock passed through our community when a son was charged with the murder of his aged father. In Lenasia at the same time a similar incident occurred where a son allegedly assaulted his father which led to the father’s death a week later. The news unsettled me in a way that felt almost personal because it echoed a fear and regret that has lingered in my own life. It reminded me that while physical abuse is the most visible form of mistreatment, there is another quieter and more insidious form that happens behind closed doors. This is caregiver neglect, which is the deliberate withholding of attention, support or even vital medical care. In many cases, it is not an accident but an intentional act hidden beneath a mask of duty and sacrifice.

I am a woman in my mid-forties, married into a very wealthy family from LLL. From the outside, people often admired my in laws for their success and lifestyle. Their wealth came from property, overseas investments, and a busy wholesale business. But beneath the surface, things were not as perfect as they seemed. My husband is the youngest of four children. Unlike his siblings, he chose his own path and built a career as an accountant. He was proud to earn his own living and didn’t rely on the family business. His brothers and sister, however, were all involved in the business in one way or another. The eldest son, MMM, had been working with their father from the time he finished school. He managed the property portfolio, learned the business under his father’s guidance, and became deeply entrenched in every decision. He carried himself as though the business belonged more to him than anyone else. My husband’s sister and second eldest brother joined later, but they never had the same authority as MMM. My husband’s parents lived with MMM and his wife, ZZZ, in the family house. Outwardly, it looked like the natural norm in society where the eldest son lived with his parents, took care of them and managed the family wealth. However, when my father-in-law passed away five years ago, that order was broken. His will divided everything into five equal shares, one for his wife and one for each of the four children. There was also a large life insurance payout, split the same way. To most families this seemed fair. To MMM, it was a shock and disappointment. He felt that since he had worked the longest and carried the most responsibility, his share should have been larger. What hurt him the most was that the house he had lived in for years was left in his mother’s name. The will also stated that he must take care of his mother, pay her living costs and only after her death would her share, including the house pass to him. This made him restless. He worried that his mother could change her will under the influence of the other children and divide her wealth equally among her four children, leaving him with less than he expected. That worry grew into a quiet obsession. The estate took three long years to sort out. Arguments about figures and shares were constant and suspicion hung in the air. In public, the family smiled and appeared united, but inside there was bitterness and mistrust.

My husband wanted no part of it. He sold his share to MMM for what we both felt was a low price, but my hubby refused to argue. His peace of mind was more important than money. This made him the only sibling seen as neutral. He maintained relationships even as the others tore one another apart. Life continued on the surface. Birthdays, gatherings and business meetings went on as usual, but the cracks were there. The disagreements over money had planted seeds of resentment and those seeds would grow, especially once the care of the mother became entangled with questions of control and inheritance. My mother-in-law was in her early seventies when my father-in-law died. She had always been lively, full of energy and warmth, enjoying visitors and conversation. But the loss of her husband hit her hard. Her memory began to fail, she repeated herself often and at times looked confused. She became quieter and more withdrawn, no longer the bright woman I had first known. She also suffered from high blood pressure, but the family doctor assured us that with both her daily blood pressure and blood thinner medication she would be fine. On the surface, ZZZ appeared to take on the role of the devoted daughter-in-law. She handled meals, medication, and doctor’s appointments. Outwardly, she seemed selfless, but to me it felt different. Whenever my mother-in law stayed with us or with one of her other children during holidays or weekends when MMM and his family were away, she seemed more alert and more lively.

Back in MMM’s house, under ZZZ’s watch, my mum-in-law was constantly tired, weak, and often asleep. I began to notice the contrast and wondered if her vitality was being deliberately limited. I even joked with my husband once that perhaps ZZZ was slipping his mum sleeping tablets so that she could go out to the gym, shopping, or socialising with her friends without having to worry about looking after her. At the time I said it lightly, but in my heart I wondered if it could be true. The siblings’ disagreements over inheritance grew sharper. The loss of their father and the unequal involvement in the business created tension. MMM became protective of his role in caring for his mother, constantly asserting his authority. It was clear that worry over her wealth had become as important to him as worry over her well-being. The siblings began to visit less often. Sometimes they complained that they were not welcome, other times they said that their mother was always asleep when they came. It was as if a wall was being quietly built between my mother-in-law and her other children.

A year and a half back, my mother-in-law fell and broke her hip, requiring surgery. She became bedridden, and a professional nurse was brought in. Under the nurse’s care, she showed improvement. She was calmer, more comfortable and even regained some cheer. For the first time since her husband’s passing, she seemed like herself again. However, ZZZ did not like having a professional around. I noticed that the nurse became nervous whenever ZZZ was near. On one occasion, I walked in unannounced and saw ZZZ shouting at my mother-in-law while the nurse tried to calm the situation. ZZZ acted as if she was shouting the nurse when she realised that I was in the room and quickly ushered me out with a lame explanation that the nurse had almost dropped my mother-in-law from her wheelchair. The nurse later admitted to me when I managed to speak to her alone while ZZZ was out shopping, that ZZZ often used harsh words and that shockingly MMM sometimes spoke sharply as well to his mother. Terrified of losing her job, the nurse begged me not to speak of it but I could not be silent on such a matter and I confided in my husband.

When my husband tentatively approached MMM about the raised voices, the nurse was immediately dismissed, under the pretext of missing money, a claim that was never proven. In her place, ZZZ brought in a maid with almost no English proficiency and no experience in elderly care, while claiming she and not the maid would personally manage meals and medication.

During the nurse’s brief care, I realised how much proper support could improve my mother-in-law’s health. The nurse treated her with kindness and attention, showing me that her decline was not simply due to age. When the nurse was removed, the maid could not maintain the same level of care, leaving ZZZ in complete control. Each visit I made confirmed my fears. When ZZZ was present, my mother-in-law seemed weak and withdrawn. When ZZZ was away, she was slightly stronger and more alert. I began to understand the pattern that control and not neglect or accident, was at the center of her declining condition.


The dismissal of the nurse and her replacement with an inexperienced maid gave ZZZ total authority. It was during this period that I discovered something that would haunt me for weeks. One afternoon, while fetching a glass of water for my mother-in-law, I happened to open the dustbin in the kitchen, to throw away a used tissue. Among the ordinary waste, the edge of a medication box caught my eye. I reached in and pulled it out. To my shock, it was a full box of her blood pressure pills, completely unused. My heart sank as I realized what it meant. These were her essential medications and were pills that she had to take every day to manage her condition. And here they were, discarded without reason. I immediately went to confront ZZZ. She went pale for a moment, but quickly regained her composure. Her voice rose sharply, and she began blaming the maid. According to ZZZ, the maid had thrown the box away by mistake, thinking it was expired. But the maid’s face told a different story. She looked utterly bewildered, her eyes wide and confused. It was obvious that she had no idea what ZZZ was accusing her of and her helplessness only confirmed my suspicion that ZZZ’s explanation was false.

At that moment, everything fell into place. The pattern I had been noticing with my mother-in-law’s constant weakness, the confusion and the lethargy was no accident. Whoever had control over her medications could control her very life.

The realisation was chilling. I rushed to tell my husband, but he refused to believe me. He said that I was being paranoid and that it must have been the maid’s mistake. I tried to argue, to make him see the pattern, but he begged me not to stir trouble. From that day, the household no longer felt safe, and the sense that my mother-in-law’s decline was deliberate became undeniable. Nine months after the nurse was dismissed, my mother-in-law passed away quietly, in her sleep. The cause was an embolism, likely worsened by withheld medication. MMM and ZZZ appeared outwardly sorrowful but their relief was palpable. They inherited my mother-in law’s wealth and the house, just as the will had intended, while questions about her personal belongings were dismissed.

Looking back, the entire sequence felt calculated. There are always voices who dismiss suspicion, claiming that accusations are malicious or that family matters should be left private. But the troubling truth is that sometimes these very suspicions, if acted upon, could save a life. The red flags may appear subtle at first with unexplained exhaustion, frequent illness, bruises and sudden changes in behaviour which if ignored often lead to irreversible loss. I saw the signs and I sensed the danger but I held back. I told myself it was not my place and I let my husband convince me that perhaps I was imagining too much. My silence became my burden and the guilt of not protecting someone so vulnerable will forever remain with me. The experience left a deep mark.


I carry regret, sorrow and the understanding of how fragile life can be when those meant to protect us fail. Wealth and loyalty can hide darker motives while appearances of care can conceal control and cruelty. I also learned the cost of silence. Moments for intervention were missed. My hesitation allowed the orchestrated neglect to continue. But from this, I learned to recognize the warning signs, to act when something feels wrong and to speak out on behalf of those who cannot defend themselves and I urge all other family members who may find themselves in a similar situation not to remain silent. The truth hurts but silence kills.
