The “Cyanide Mallika”: Revisiting India’s First Female Serial Killer

Last updated: July 2026

K.D. Kempamma, infamously known as “Cyanide Mallika,” is recognized as India’s first female serial killer. Operating in Bengaluru temples between 1999 and 2007, she poisoned at least six women using cyanide-laced offerings during fake religious rituals, killing for gold jewelry and cash before her 2008 arrest.

Who Was Cyanide Mallika?

K.D. Kempamma remains one of the most chilling figures in Indian criminal history, having shattered the traditional archetype of the serial killer. Unlike the impulsive violence often seen in serial crimes, Mallika’s murders were calculated, cold-blooded, and driven by a singular, ruthless motivation: greed. She did not operate in shadow and brute force, but through feigned piety and maternal comfort, exploiting the spiritual vulnerability of women seeking divine intervention for their problems.

Born into poverty in Karnataka, Mallika understood the psychology of desperation. She recognized that temple complexes across Bengaluru attracted thousands of devotees daily, many of them women carrying visible wealth and invisible burdens. This became her hunting ground, where faith and desperation intersected, creating the perfect environment for predatory manipulation.

How Did Cyanide Mallika Choose and Kill Her Victims?

Mallika’s modus operandi was as consistent as it was cruel. She would frequent bustling temple complexes, scouting for women who appeared visibly distressed or burdened by family woes. Her victims were typically middle-aged women wearing gold jewelry, often dealing with marital problems, financial difficulties, or illness in the family.

Presenting herself as a knowledgeable “Godwoman” or a sympathetic devotee, she would gain their absolute trust. With practiced ease, she would convince her victims to accompany her to secluded spots or rented rooms to perform a “Mandala Puja,” a ritual she claimed would solve all their problems. Under the guise of religious devotion, she would instruct them to close their eyes in prayer and consume “holy water” or “prasad” laced with deadly cyanide.

As her victims struggled for breath, Mallika would calmly watch them die before stripping their bodies of gold jewelry, cash, and other valuables. She would then vanish into the crowded streets of Bengaluru, leaving the bodies to be discovered hours or days later. The deaths were often initially attributed to natural causes or heart attacks, allowing Mallika to continue her killing spree undetected for nearly eight years.

What Led to Cyanide Mallika’s Arrest?

The reign of the “Cyanide Mallika” finally ended in 2008 when she was apprehended while attempting to sell stolen ornaments at a jewelry shop in Bengaluru. The jeweler became suspicious of the quantity and variety of gold items she was trying to sell and alerted the police. When authorities questioned her, inconsistencies in her story prompted a deeper investigation.

Her arrest unraveled a trail of six confirmed murders that had left local police baffled for years. Investigators had noticed a pattern of mysterious deaths among temple-going women, but the geographic spread across different police jurisdictions and the seemingly natural appearance of the deaths had prevented earlier detection. Once in custody, forensic evidence linking cyanide traces to the victims, combined with witness testimonies from temple visitors who had seen Mallika with the deceased women, built an overwhelming case against her.

The Psychology Behind India’s First Female Serial Killer

During her trial, Mallika showed a startling lack of remorse, viewing her victims merely as means to a financial end. This cold pragmatism shocked investigators and the public alike. Female serial killers remain statistically rare worldwide, accounting for only 10-15 percent of serial murder cases. When women do kill serially, they typically use poison (as Mallika did), often target people they know, and are motivated by financial gain rather than sexual gratification or power.

Mallika’s case fits this profile almost perfectly. She weaponized the very thing that made her victims vulnerable: their faith. By exploiting religious rituals and the trust inherent in spiritual spaces, she created a predatory model that was nearly invisible to law enforcement. The sacred context of her crimes made victims less suspicious and authorities slower to connect the deaths.

Criminologists studying her case note that Mallika displayed classic psychopathic traits including lack of empathy, superficial charm, manipulativeness, and an instrumental view of other human beings. Her ability to maintain a facade of piety while systematically murdering vulnerable women demonstrates a level of compartmentalization and emotional detachment rarely seen in female offenders.

Why Does the Cyanide Mallika Case Matter in 2026?

Today, nearly two decades after her arrest, Mallika’s legacy serves as a haunting reminder of how easily the mask of religion can be used to camouflage a predator. Her case remains a cornerstone of Indian true crime, proving that the most dangerous villains are often those who blend seamlessly into the sacred spaces of daily life.

The case has had lasting impact on how Indian law enforcement approaches serial crimes, particularly those involving women as perpetrators. It challenged assumptions that serial killers in India would follow Western patterns and highlighted the need for better inter-jurisdictional communication among police departments. Temple authorities across Karnataka and other states have since increased security measures and awareness campaigns warning devotees about strangers offering unsolicited spiritual help.

In recent years, Mallika’s story has been featured in true crime documentaries, podcasts, and has been referenced in popular culture as India’s criminal justice system continues to study rare cases of female serial offenders. The case serves as a critical teaching example in forensic psychology courses across Indian universities and police training academies.

Frequently Asked Questions About Cyanide Mallika

How many people did Cyanide Mallika actually kill?

Mallika was convicted of six murders committed between 1999 and 2007. However, investigators believe the actual victim count may be higher, as some deaths may never have been connected to her or may have occurred in jurisdictions where records were incomplete.
