In Alwar, Rajasthan, Santosh Sharma (alias Sandhya) conspired with her lover Hanuman Prasad and two accomplices, Deepak and Kapil, to murder her husband, Banwari Lal Sharma, their three sons, and her 10-year-old nephew Nikki. Dissatisfied with her husband's income as a factory operator and desiring a luxurious life, Santosh began an affair with Hanuman, whom she met through Taekwondo coaching trips. When Banwari Lal and her eldest son Mohit discovered the affair and restricted her movements, Santosh and Hanuman plotted to kill them. Over several months, they procured fake SIM cards, purchased an online slaughtering dagger and knife, and obtained sleeping pills. On the night of October 1, 2017, Santosh laced her family's raita with sedatives. Around 1:00 AM on October 2, 2017, she let Hanuman, Deepak, and Kapil into the house, directing them to the sleeping family members. The group slit Banwari Lal's throat and stabbed all five sleeping victims to death. Police subsequently recovered blood-stained clothes, weapons, and mobile records linking the co-conspirators. Six years after the crime, the court sentenced all four accused to life imprisonment.

Infidelity
The case illustrates an extreme escalation of extramarital conflict driven by financial discontent and coercive desire for personal liberty. Santosh Sharma felt dissatisfied with her husband's modest earnings and established a secret romantic relationship with Hanuman. When her husband and eldest son discovered the affair and curtailed her travel, the extramarital dynamics shifted from concealment to premeditated liquidation of the primary family unit.
Police solved the case using technical intelligence, tracking seven mobile devices and call logs associated with fake SIM cards used exclusively between Santosh and Hanuman Prasad. Forensic recovery included blood-stained clothes from a bag in Udaipur, the discarded murder weapon near Rajgarh, and a scooty used during the escape. All four defendants—Santosh, Hanuman, Deepak, and Kapil—were convicted and sentenced to life imprisonment six years post-incident.
Initially, the perpetrators attempted to mask their identity by purchasing weapons online and local market knives under the assumption that untraceable tools and pre-sedating victims would prevent scene disruption or immediate alarm. However, mobile location data and weapon recovery swiftly dispelled early scene ambiguity.
Reconstruction indicates that Santosh ground sleeping pills on a domestic grinding stone and mixed them into raita served during dinner on October 1, 2017. After confirming the family was incapacitated via phone at 9:44 PM, she admitted Hanuman, Deepak, and Kapil into the home at 1:00 AM on October 2. Santosh personally pointed out her husband, leading to his throat being slit, before all remaining occupants—including three children and a nephew—were stabbed to death. The group washed their hands at a water tank in Mandi Mor before fleeing.
The combination of severe marital dissatisfaction, hidden romantic attachment, physical mobility through independent work, and violent elimination planning represents an acute risk environment. Risk escalated sharply when the victim and his son confronted the offender and attempted to restrict her behavior, triggering a lethal conspiratorial response.
Premeditated domestic homicides involving multi-offender conspiracies often leave distinct digital footprints, such as secondary communication channels and specialized tool acquisitions. Family intervention in extramarital disputes without secondary security measures can lead to violent retaliation when an offender feels cornered.
Early signals included Santosh's repeated prolonged absences from home under the guise of sports training, financial dissatisfaction with her husband's factory wage, and secretive phone interactions.
Key clues included call detail records on secondary SIM cards purchased with false identities, the online purchase history of a 31 cm slaughtering dagger, and witness observations of Santosh pulverizing pills on a grinding stone.
Strong evidence included seven recovered mobile phones, call logs between Santosh and Hanuman, blood-stained clothes retrieved from Udaipur, the murder weapon found near Rajgarh, and physical recovery of the getaway scooty.
Santosh's younger sister Kavita reported seeing Santosh grinding unidentified tablets on a grinding stone before the dinner meal and stated she was harshly reprimanded and ordered to keep silent when questioning her sister.
Initial reports of a home intrusion were disproved after investigative focus turned inward toward family call records, revealing Santosh's explicit active facilitation of the killers' entrance.
The narrative explicitly accounts for the trial outcome and life sentences, leaving no major investigation uncertainties unresolved.
