Supreme Court says,

9. No explanation is forthcoming from the statement of the accused under Section 313 Cr.P.C. as to when he parted the company of the victim. Also, no explanation is there as to what happened after getting the chocolates for the victim. The silence on the part of the accused, in such a matter wherein he is expected to come out with an explanation, leads to an adverse inference against the accused.

Circumstantial Evidence…

10. We find that there is ample material against the accused to convict him for the offence under Section 302 IPC. All the circumstances relied upon by the prosecution stand proved so as to complete the chain of circumstances in respect of the offence under Section 302 of the IPC. The Trial Court and the High Court are, on facts, justified in convicting the accused for the offence under Section 302 of the IPC. However, we are unable to find reliable material against the accused for the offences under Section 3 and 4 of the POCSO Act.
