Witness' relationship with victim per se NOT proof of prejudice

Appellant assail the credibility of Glenn Huelva, the prosecution's lone witness, by pointing out his relationship with the victim and as such his testimony is tainted with bias. Aside from this general averment in their brief, however, not an iota of evidence was ever presented at the trial to prove this charge. Relationship with the victim per se is not proof of prejudice. Nor is it a sufficient motive to testify falsely. [G.R. No. 95049. December 9, 1996]
