Penal Code, 1860–Sec. 302–Conviction–Circumstantial evidence–Witness of last seen is not reliable as he improved his statements–Extra-judicial confession before a unknown person also cannot be believed–Recovery u/s. 27 cannot be relied on as it was not established by prosecution–Body of deceased was recovered in skeleton and could not be identified–DNA test has no significance as nothing is available on record to show that who took the samples of DNA of PW 1–No motive was alleged by prosecution–Held, it would not be safe to convict the appellant.
