In 2020, a homicide in a nondescript village of Kerala sent shock waves across the country. Who were the perpetrators? How was the evidence collected? Why did the prosecution want the crime to be classified as ‘rarest of rare’? In the gruesome crime that was committed, a husband was alleged to have murdered his wife by inducing cobra bites. The police worked round-the-clock under intense pressure to collect evidence in a case where the slithering ‘murder weapon’ had a mind of its own. State-of-the-art investigation techniques were employed, witnesses were interrogated, and immunity deals were struck, leading to a landmark judgment of double life imprisonment.
