On February 4, 2019, in Hoshangabad (Narmadapuram), Madhya Pradesh, India, Dr. Sunil Mantri, an orthopedic doctor, allegedly sedated and murdered his driver, Virendra. Dr. Mantri was involved in an extramarital affair with Virendra's wife, Rani. After Virendra discovered call recordings revealing the affair, he reportedly began blackmailing Dr. Mantri for money. Dr. Mantri lures Virendra under the pretext of treating a toothache, sedated him with an injection, and then dismembered his body into over 500 pieces using surgical blades and hacksaws, attempting to dissolve the remains in containers filled with acid. On February 5, 2019, after Virendra's father raised an alarm outside Dr. Mantri's home, police searched the premises and discovered blood, hacksaws, body parts, and Virendra's head floating in an acid-filled tub. Despite initial denials, false robbery claims, redirected cell phone locations, and false alibi testimony provided in court by Rani to protect Dr. Mantri, police established Dr. Mantri's guilt using forensic DNA matched from his jail nail trimmings against crime scene samples. Dr. Mantri was convicted and sentenced to life imprisonment.

Romantic Triangle
The incident stems from an extramarital relationship between Dr. Sunil Mantri and Rani, the wife of his driver Virendra. After Virendra discovered call recordings detailing the affair, he engaged in blackmail and financial extortion against Dr. Mantri. The conflict escalated to fatal violence when Dr. Mantri sedated Virendra under medical pretexts and systematically dismembered his body to evade detection.
Police initially faced deceptive narratives, including claims of an external robbery and redirected cell phone signals to Bhopal. Despite hostile alibi testimony from the victim's wife during court proceedings, police successfully matched DNA extracted from Dr. Mantri's jail nail trimmings with crime scene blood and tissue samples, resulting in a life sentence.
Investigators were challenged by Dr. Mantri's initial assertions of being out sightseeing, his secondary claim that Virendra was killed by greedy co-conspirators over ₹20 lakh, and Rani's court testimony providing Dr. Mantri an alibi while Virendra's phone pinged near Bhopal.
Forensic evidence established that on February 4, 2019, Dr. Mantri sedated Virendra at his home, killed him, and dismembered his body into over 500 pieces using surgical instruments and hacksaws. He attempted to dissolve the parts in acid tubs. On February 5, 2019, police responded to a disturbance raised by Virendra's father, searched the residence, recovered the head and body parts, traced acid sales to Dr. Mantri, and secured forensic DNA verification.
Extremely high risk driven by secret extramarital involvement, financial blackmail, specialized medical access to sedatives and surgical equipment, and methodical post-incident efforts to dissolve evidence in acid and fabricate judicial alibis.
Infidelity combined with financial extortion creates severe lethal dynamics. Perpetrators with medical expertise can attempt extreme body destruction and evidence concealment, emphasizing the essential role of objective forensic DNA testing over witness testimony.

Statements from local shopkeepers confirming Dr. Mantri purchased 20-liter acid cartons, acid containers inside Dr. Mantri's car trunk, and Virendra's bloodstained clothes hidden in a home cabinet.
Severed head and body parts in acid containers, four hacksaws, surgical blades, acid purchase records, call recordings, and forensic DNA matching from Dr. Mantri's nail trimmings.
Lakshmi Narayan stated his missing son was last seen working as Dr. Mantri's driver and identified his severed head in the bathroom. Rani initially claimed her husband was missing, but later testified in court that Dr. Mantri was at her home and her husband had traveled to Bhopal. Shopkeepers confirmed selling acid cartons directly to Dr. Mantri.
A missing person investigation converted into a dismemberment homicide inquiry upon searching Dr. Mantri's residence. During the trial, Rani turned hostile to protect Dr. Mantri, but forensic DNA evidence disproved her statements.
Whether Rani actively assisted in planning the murder or only attempted to misdirect the judicial process after the crime.
