Prakash v. State of Karnataka
Background
Gangamma was found murdered in her Bangalore home after receiving visitors the previous day. Investigators relied on Prakash's earlier visit, alleged fingerprint matches, bloodstained clothes and recovered jewellery and a steel rod. The trial court acquitted him, but the High Court reversed that decision on circumstantial evidence.
Decision Breakdown
The Supreme Court allowed the appeal and acquitted Prakash of murder. A visit at one in the afternoon did not establish his presence that evening, when other unidentified relatives were present. The specimen fingerprint's origin was unproved, the blood-group match did not identify the victim's blood, and the recovered jewellery was not established as hers. Material evidence was inadequately tested, and the High Court could not replace questioning the accused with asking his lawyer to explain a serology report on appeal. The prosecution had failed to prove a complete chain, and the trial court's reasonable acquittal should have stood.
Lesson Learnt
Suspicion and apparent scientific matches cannot replace proof that evidence was properly collected and linked to the crime. Each circumstance must be proved before the combined chain can establish guilt beyond reasonable doubt.
