Delhi Murder Plot: Woman, Brother-in-Law Kill Husband.

July 19, 2025 | New Delhi, India
A shocking Delhi murder plot has exposed a chilling betrayal within a family. A woman and her brother-in-law, who were reportedly having an affair, have been arrested for drugging and killing her husband. The crime was carefully planned and disguised as a domestic accident.

Delhi Murder Plot Orchestrated by Wife and Brother-in-Law

On July 13, Karan Dev, a 36-year-old resident of Dwarka and government employee, was found dead inside his home. His wife, Sushmita, initially claimed he died from electric shock while operating a water motor. However, inconsistencies soon raised suspicion.

Karan’s younger brother, Kunal, had doubts about the story and insisted on a post-mortem. While the rest of the family hesitated, the autopsy revealed shocking details. Karan had not died due to electrocution, but from poisoning and suffocation.

Investigation Reveals Chilling Delhi Murder Plot

Delhi Police launched an investigation after noticing inconsistencies in the physical evidence at the scene. There were no burn marks on Karan’s body. The electrical circuit was also functioning, indicating no short-circuit or electrocution had occurred.

The case took a darker turn when police found Instagram chats between Sushmita and her brother-in-law, Rahul. They were involved in a secret romantic relationship and had been planning the murder for weeks.

Key Steps in the Murder Plan

The couple first administered 15 sleeping pills to Karan by mixing them in his food. Once Karan was unconscious, they tied electric wires to his feet to simulate accidental death. Sushmita then informed the police that he had been electrocuted while fixing the water pump.

However, forensic results showed the sedative in his bloodstream. The absence of electric burns confirmed that the death was not accidental. When confronted with evidence, both Sushmita and Rahul confessed to their roles in the crime.

Motive Behind the Delhi Murder Plot

According to Sushmita’s confession, her marriage had been deeply troubled. She accused Karan of physical abuse and said he often demanded money. She also alleged that he forced her to transfer funds to his relatives and limited her financial freedom.

The situation worsened around last year’s Karwa Chauth, when an argument escalated into threats and violence. It was during this period that Sushmita became close to Rahul. Their bond intensified and eventually turned into a romantic relationship.

Secret Affair Ignites Deadly Plan

Rahul, Sushmita’s cousin and Karan’s younger brother, frequently visited the family. Over time, he and Sushmita developed a secret relationship. Their chats revealed mutual frustration with Karan and a desire to be together.

They discussed various ways to get rid of Karan, finally deciding on the use of sedatives and a staged accident. After Karan fell asleep from the drugged meal, they executed the plan late at night, hoping no one would question the setup.

Police Action and Legal Charges

Both Sushmita and Rahul have been arrested under Indian Penal Code sections related to murder and criminal conspiracy. Delhi Police confirmed they are also investigating if any third person assisted or had prior knowledge of the plan.

Officers credited Kunal’s insistence on a post-mortem for cracking the case. The police commissioner praised the forensic team and investigators for acting swiftly and decisively.

Reaction from the Victim’s Family

Karan’s family expressed shock and heartbreak. They were unaware of the growing tension between the couple. His brother, devastated by the betrayal, stated that Sushmita had always portrayed herself as a loving wife.

The family is now demanding a speedy trial and maximum punishment for both accused. They also urged authorities to ensure justice is served without delays.

Delhi Murder Plot a Stark Reminder of Hidden Dangers

This Delhi murder plot underscores the dangers of unresolved domestic conflict, hidden abuse, and betrayal within families. The case also highlights the importance of post-mortem investigations in uncovering hidden truths.

Thanks to early intervention by Kunal and the meticulous work of the Delhi Police, the truth was revealed before it was buried under a fake accident story.
