A 28-year-old man was found stabbed to death at his home in Madhya Pradesh's Dhar district earlier this week.
Police later uncovered an alleged murder conspiracy involving his wife and her lover.
The victim, Dev Krishna Purohit, was killed on the intervening night of Monday and Tuesday at his residence in Gondikheda Charan village.
His wife, Priyanka Purohit (25), initially claimed that unidentified assailants had broken into their house and escaped with valuables.
However, police began to suspect foul play after noticing inconsistencies in her account.
Investigation revealed a planned killing, with Priyanka and her lover, Kamlesh Purohit, allegedly conspiring to remove Dev Krishna, whom they saw as an obstacle.
The plan involved hiring a contract killer for ₹1 lakh to carry out the murder.
Technical evidence, including mobile phone data, played a key role in unravelling the case.
Priyanka eventually confessed to her role in the conspiracy, and police arrested her and Kamlesh.
