Investigation Failures Under Spotlight as Supreme Court Overturns Three Murder Convictions in September First Week
The Supreme Court has, in the first week of September 2026, overturned convictions in three separate murder cases involving very different factual circumstances. Despite the differences, the cases share a significant common thread: the prosecution failed to establish the accused persons’ guilt beyond reasonable doubt, with serious weaknesses emerging in investigation, evidence collection and proof.
The first case, Dhrub Singh v. State of Bihar, concerned a broad-daylight murder allegedly committed during an election period. The Supreme Court on September 1 set aside the convictions of the accused after finding serious shortcomings in the prosecution’s case and police investigation.
The prosecution alleged that the accused had opened indiscriminate fire, resulting in the victim’s death. However, the police failed to recover cartridges from the crime scene and did not recover the alleged weapons. Blood-stained earth collected from the scene was also not sent for chemical analysis. These investigative omissions weakened the prosecution’s case substantially.
The Supreme Court also rejected an attempt to explain away the investigating officer’s shortcomings by referring to an allegation of collusion against the officer. The Court made it clear that an unproved document or allegation cannot be used to strengthen a prosecution case that otherwise lacks reliable evidence.
The Court’s important observation was that a faulty investigation does not automatically benefit an accused. But equally, the court cannot presume guilt merely because an investigating officer may have been negligent or accused of collusion. The prosecution still has to prove the case through reliable evidence.
The second case, Sahab Singh v. State of Haryana, involved the murder of a six-year-old child. The accused had spent approximately 16 years in prison after being convicted on the basis of circumstantial evidence. The Supreme Court found that several essential links in that chain were missing and set aside his conviction.
The prosecution had relied on circumstances including the alleged “last seen” theory, an extra-judicial confession, a disclosure statement and biological evidence. But when the Court examined these pieces individually and collectively, they failed to form an unbroken chain pointing only towards the accused.
One unusual piece of evidence was a packet of namkeen allegedly connecting the accused with the child. The Court found this circumstance inadequate because the product was generic and widely available in the village, with no evidence establishing that the particular packet recovered had any connection with the accused.
The alleged extra-judicial confession also failed to provide the necessary link. The Court treated such evidence with caution, particularly because the alleged confession was made to a village sarpanch who had no established relationship with either the accused or the deceased.
The biological evidence raised an even more significant investigative problem. Although semen was reportedly detected on the accused’s underwear and on a rectal swab taken from the deceased, no DNA examination was conducted to establish whether the two samples were connected. The missing scientific link therefore prevented the prosecution from drawing the necessary inference.
The third case, Kondapaka Sridhar v. State of Telangana, involved a kidnapping-for-ransom case that ended in murder. On September 3, the Supreme Court acquitted the surviving accused after finding that the prosecution’s case was substantially based on confessions and an unsubstantiated narrative rather than legally proved substantive evidence.
In that case, the victim disappeared after leaving home for Hyderabad and a ransom demand followed. Money was deposited into a bank account allegedly connected with the accused. Police subsequently arrested another accused, whose alleged confession led investigators to the body, which was found concealed inside a refrigerator in an apartment.
The Supreme Court found serious evidentiary problems with this investigation. The alleged confessions of co-accused could not be treated as substantive evidence to establish the involvement of the appellant. The Court also found that crucial electronic evidence, including CCTV footage and call records, had not been properly proved in accordance with the applicable evidentiary requirements.
The call records were particularly important because the investigating officer claimed that their analysis had led police to one of the accused. But the telecom company’s nodal officer was never examined and the required certificate was not produced. The Court therefore found that the prosecution’s narrative based on those records could not stand.
The prosecution also failed to establish that the apartment where the body was found had actually been leased by the appellant. Without proving that foundational fact, the prosecution could not successfully invoke the principle requiring an accused to explain facts particularly within his knowledge. The “last seen” theory likewise remained unproved.
Taken together, the three judgments highlight a fundamental principle of criminal law: suspicion, investigative assumptions and incomplete circumstances cannot substitute for legally admissible and reliable evidence. A murder may have unquestionably occurred, but the prosecution must still prove beyond reasonable doubt that the particular accused committed it.
The September rulings also underline the importance of the quality of investigation at the earliest stage. Failure to recover physical evidence, failure to scientifically analyse material, failure to properly prove electronic records and excessive reliance on confessions can create gaps that become impossible to repair at the appellate stage.
The Supreme Court’s approach does not mean that every investigative lapse will result in an acquittal. Rather, the decisive question remains whether the evidence that survives scrutiny is sufficient to establish guilt beyond reasonable doubt. Where the investigation is defective and the remaining evidence cannot independently establish guilt, the constitutional and criminal-law principle of reasonable doubt must operate in favour of the accused.
The three decisions therefore send a strong message to investigating agencies and prosecutors: a conviction cannot rest on a story constructed around gaps in investigation. Evidence must be collected, preserved, scientifically examined and legally proved. Where those foundations are missing, even serious criminal allegations cannot sustain a conviction.
