In this criminal appeal filed by the State of Himachal Pradesh, the Supreme Court examined whether the High Court was justified in setting aside the trial court’s judgment convicting and sentencing the respondent-accused under Section 302 of the Indian Penal Code, 1860, for the double murder of her stepmother and minor stepbrother. The prosecution relied heavily on circumstantial evidence, including the “last seen” theory, taxi travel logs, hotel stays, recovery of keys and a mobile phone via disclosure, and DNA profile matching of bloodstains found at the crime scene. Upon re-evaluating the record, the Supreme Court held that the prosecution failed to establish a complete and unbroken chain of circumstances pointing exclusively to the guilt of the accused. Finding serious investigational lapses—such as omitted mobile tower locations, untrustworthy corroborative witnesses, and non-conclusive forensic links—the Court upheld the High Court’s acquittal and dismissed the appeal.
- Homicidal Death and Timing: While autopsy confirmed homicidal death by strangulation 5 to 7 days prior to the post-mortem, the timeline did not conclusively restrict the time of death to the intervening night of August 31 and September 1, 2011.
- “Last Seen” Theory: The sole witness to the last seen circumstance (PW-1, the father of the deceased) made material improvements from his previous Section 161 CrPC statement, and his long delay in reporting the locked house rendered his testimony unconvincing.
- Taxi and Hotel Evidence (PW-4 and PW-18): The testimonies regarding the accused hiring a taxi to Diur and staying at a Chamba hotel were deemed untrustworthy, as the investigating officer failed to explain what prompted recording their statements, and no hotel guest registers were produced.
- Lock Breaking and Key Recoveries: The prosecution failed to establish that the lock produced in court was the exact lock hanging on the door’s latch rather than its handle, rendering the subsequent discovery of keys inconsequential.
- Mobile Phone Recovery and CDR Lapses: The failure of the investigating agency to retrieve and exhibit the complete Call Detail Records (CDR) along with mobile tower locations represented a severe investigational lapse, obscuring the actual location and active status of the devices.
- DNA Profile Matching: Although the DNA profile from a blood scrape on a cabinet matched the accused’s blood sample, this was not conclusive because the accused was a regular visitor to the house, and no blood of hers was found on the victims’ clothing or the murder weapon.
- Absence of Motive: The prosecution failed to prove any formal property bequest in favor of the minor deceased, weakening the alleged financial motive for the crime.
