As per case facts, Rekha Dutta was last seen with the appellants and Jit Kakati in a bungalow. Her family inquired about her whereabouts but received no clear answers. Later, ... a dismembered body, identified as Rekha Dutta, was found on a railway track. The appellants and Jit Kakati surrendered. The Trial Court acquitted them, but the High Court reversed this, convicting them for murder and destruction of evidence based on the "last seen" theory. The question arose whether the High Court's conviction, relying primarily on the "last seen" theory in a circumstantial evidence case, was legally justified when other links in the chain of evidence were not established. Finally, the Supreme Court held that the prosecution failed to prove crucial circumstances like the recovery of the weapon and blood stains. It reiterated that the "last seen" theory alone, without a complete chain of other supporting circumstantial evidence that points solely to the accused's guilt and excludes all other hypotheses, is insufficient for conviction. Consequently, the High Court's judgment was set aside, and the appellants were acquitted, emphasizing the strict requirements for conviction in circumstantial evidence cases.
