took place. In this regard, investigating officer did not record further statement of P.W.11 and P.W.14. Therefore, the evidence of P.W.11, P.W.14 and P.W.18 about the conspiracy among A1 to A3 is not reliable. Likewise, L.W.5, L.W.6, L.W.7 were also cited as witness to prove the conspiracy. L.W.5 - one Suresh and L.W.6 - one Thangaraj have been examined as P.W.1 and P.W.2. Both turned hostile and did not support the prosecution case. One Yovan – L.W.11 had been examined as P.W. 12, to prove the motive. During chief examination, he had stated that himself and accused Iyappan were cited as witnesses in Guruswamy case. Accused Nos.2 and 3 threatened him on 03.03.2004, at night 01.45 a.m., not to depose evidence against them in that case or they will do away with them and on 22.03.2004, murdered Iyappan. Therefore, he called A2 and A3 viz., Mahalingam and Kannan through phone and questioned them why they murdered Iyappan, for which, both asked whether they wanted to do the same to him, and immediately, he kept the phone. He had lodged a complaint before the Thirukurunkudi Police Station for self protection. However, no such complaint or phone call details had been produced by prosecution to prove that a complaint was lodged by P.W.12. His statement was contrary to his statement under Section 161
