Circumstantial evidence in murder cases must first prove homicide; suspicion and post-occurrence conduct cannot replace proof.

In a circumstantial evidence prosecution for murder, the prosecution must first prove beyond reasonable doubt that the death was caused by a homicidal act. Where medical evidence does not conclusively distinguish homicide from suicide, and the chain of circumstances does not establish that a crime was committed, the burden does not shift to the accused merely because some facts may be within his special knowledge. Suspicion based on post-occurrence conduct cannot fill the gap in proof, and where two reasonable inferences arise, the one favourable to the accused must be adopted unless clearly displaced by reliable evidence. On these principles, the murder conviction could not stand.

Issues: Whether the prosecution proved beyond reasonable doubt that the deceased's death was homicidal and that the appellant was guilty of murder on circumstantial evidence.

Analysis: The evidence was entirely circumstantial and the medical evidence did not conclusively establish whether death was caused by homicide or suicide. The prosecution was required to prove first that a crime had been committed, and the burden did not shift to the accused merely because some facts may have been within his special knowledge. Suspicion arising from the appellant's conduct after the occurrence could not safely be used to supply the missing proof that the death was homicidal. Where two reasonable interpretations are possible, the one favourable to the accused must be adopted unless clearly displaced by reliable evidence.

Conclusion: The prosecution failed to prove that the deceased's death was homicidal, and the conviction for murder could not stand.

Ratio Decidendi: In a case based wholly on circumstantial evidence, the prosecution must first prove that the death was the result of another person's act before any adverse inference can be drawn against the accused, and suspicion or post-occurrence conduct cannot substitute for proof of homicide.
