Circumstantial evidence in murder cases can be completed by an accused's false explanation and failure to explain deaths inside the home.

In a murder case based on circumstantial evidence, the Court reaffirmed that the circumstances must form a complete chain pointing unerringly to guilt. It treated the prosecution's evidence of cruelty and money demand, the false claim of snake bite, the medical finding of death by strangulation, the suspicious placement of the body, and recoveries at the accused's instance as a coherent chain. Where the death occurred inside the matrimonial home, the accused's failure to give a plausible explanation for facts especially within his knowledge justified an adverse inference under Section 106 of the Evidence Act, and the false or absent explanation became an additional link in proof.

Issues: Whether the appellant's conviction for murder could be sustained on circumstantial evidence and whether the accused's failure to explain facts especially within his knowledge, in a case of death inside the matrimonial home, furnished an additional link in the chain of circumstances.

Analysis: The prosecution proved a consistent pattern of cruelty and demand for money, the false explanation that the deceased had died of snake bite, the medical evidence showing death by asphyxia due to strangulation, the suspicious placement of the body to simulate a natural death, and recoveries at the appellant's instance. In a case resting on circumstantial evidence, the circumstances must form a complete chain pointing unerringly to guilt. Where the occurrence takes place inside the privacy of a house and the relevant facts are especially within the knowledge of the inmates, Section 106 of the Evidence Act justifies drawing an adverse inference from the accused's failure to offer a plausible explanation. An untrue or absent explanation on an incriminating circumstance becomes an additional link in the chain of proof.

Conclusion: The conviction under Section 302 of the Indian Penal Code, 1860 was rightly sustained and the appeal was without merit.
