The human he@rt, when governed by envy and obsessive love, can be driven to unthinkable acts. Our story explores the tragic consequences when two women—one in Indonesia, the other in Vietnam—crossed the line from betrayal into calculated, fatal assault against their rivals.

Their crimes were fueled by a single, destructive desire: to eliminate the obstacles separating them from the men they were determined to claim.

Part I: The Poisoned Fish and the Love Trap

Marisa Eka Putri (25), a smart, attractive car dealer in Pekanbaru, Indonesia, found herself consumed by a toxic obsession after reconnecting with her high school friend, Inda Dewi Gibran (27).

Marisa was initially delighted to rekindle the friendship, but her feelings curdled into intense envy upon meeting Inda’s husband, Joyo.

Marisa was deeply impressed by Joyo’s kindness and devotion to his wife and child, a life she coveted. Marisa’s covert romantic advances toward Joyo were firmly rejected, as Joyo remained faithful to his wife.

Marisa’s envy intensified when she learned the couple planned to have another child. Driven by the destructive realization that she could not win Joyo’s affection, Marisa formed a brutal scheme: she would eliminate Inda.

Marisa invited Inda to her apartment under the pretense of friendship. There, Marisa cooked a fish meal, secretly lacing it with a de@dly chemical.

Inda consumed the poisoned food and Marisa, maintaining her facade, later drove her friend home. Once home, Inda suddenly collapsed and succumbed to the poisoning shortly after arriving at the hospital.

Doctors initially suspected food poisoning from spoiled fish, and Marisa was immediately present to “comfort” the grieving widower, Joyo, lending him money for the funeral expenses.

The Husband’s Revenge

Marisa was overjoyed when Joyo began reciprocating her advances a month later. Unbeknownst to Marisa, Joyo had grown suspicious that she was involved in his wife’s passing.

Joyo, while feigning affection for Marisa, secretly arranged for an autopsy on his wife’s remains, which confirmed the presence of a deadly chemical.

Joyo then orchestrated a trap: during a drinking session with Marisa, he subtly guided the conversation toward Inda’s de@th. Marisa, intoxicated and convinced of Joyo’s newfound love, inadvertently confessed to poisoning her friend.

Joyo immediately reported the crime to the police, presenting the evidence he had gathered. Marisa was arrested and confessed to the poisoning, admitting her sole motive was to eliminate Inda and claim Joyo for herself.

Though Marisa was found guilty of murder, she was sentenced to a relatively low eight years imprisonment, as the court found no direct evidence that she administered the fatal dose (relying on her confession). Joyo, having secured justice for his wife, was satisfied with the outcome.

Part II: The Poisoned Milk Tea and the Mistaken Victim

A similar tragedy unfolded in Vietnam, rooted in rejection and obsessive love. Lay Trang (28), an orphaned bank employee, was reunited with her cousin and best friend, Bean Pham.

Lay quickly grew intensely envious of Bean’s happy family life, which included her husband, Kang. This envy soon developed into an affair with Kang.

In October 2019, Kang ended the affair, realizing the wrongfulness of his actions and devastating Lay, who was obsessively in love with him.

Unable to accept the rejection, Lay developed a twisted plot: she would cause the loss of her cousin, Bean’s life, to reclaim Kang.

Knowing Bean loved taro-flavored milk tea, Lay purchased six milk teas and injected a deadly chemical into the taro one using a syringe.

Disguising herself as a delivery rider (wearing a mask and hat), Lay delivered the poisoned drinks to the hospital where Bean worked, instructing the front desk nurse that the taro flavor was “special” and for Bean.

Tragically, Trinh (Trina), a coworker of Bean, took the taro-flavored milk tea. She collapsed after drinking half of it and quickly succumbed to the poisoning.

Police traced the delivery to Lay, who was quickly arrested. Lay confessed that Bean was her intended target, admitting her motive was to eliminate her rival and secure Kang for herself.

Lay was charged with homicide. She continued to argue that her intent was only to cause the loss of her cousin’s life, not Trinh’s.

In July 2020, despite her claims of intent, Lay Trang was convicted of murder and sentenced to de@th by firing squad. The tragic irony was that her meticulous plot, driven by obsession, resulted in the loss of an innocent life, while her intended victim, Bean, was spared.

The stories of Marisa and Lay serve as profound warnings against the destructive power of obsessive love and the tragic consequences of betraying trust to pursue a man who belongs to another.
