furnished by the appellant, as per Ext.P8(a), the tapper's knife was recovered from a place, where it was stated to be thrown by the appellant after the incident. The investigating officer, PW.15, proved the confession statement and also the recovery made as per Ext.P8(a) mahazar. PW.11 who is an independent witness has also supported the recovery of MO.1 by the appellant. Therefore, the version given by the occurrence witnesses regarding the involvement of the appellant is supported by medical evidence and also the recovery under Section 27. Ext.P16, forensic science lab report shows that MO.1 contained human blood, though grouping was not possible owing to insufficiency of quantity of blood. Normally, in a case proved by occurrence witnesses, proof of motive is not necessary. But, in this case, the incident leading to execution of Ext.P1 settlement between the deceased and Chandran, the brother of Sugandhi, offer the motive for the crime, according to the prosecution. There is no reason for us to discard the said case of the prosecution.
