Accused-appellant's uncorroborated alibi crumbles in the face of such positive identification made by an eyewitness, especially since there is no showing that the witness was impelled by evil motives in imputing the offense on the accused-appellant. Furthermore, accused-appellant failed to prove that it was impossible for him to be at the crime scene at the time of its commission. He alleged that on August 24, 1992, at 8:00 in the evening, he was sleeping in his parents' house in Sta. Cruz, Calapan, Oriental Mindoro. It has not been shown, however, that Barangay Gamao is absolutely inaccessible from Sta. Cruz, Calapan, Oriental Mindoro as to preclude any possibility of the accused-appellant going there in the evening of August 24, 1992. Accused-appellant also did not present any witness to corroborate his alibi. It is settled that for an alibi to be credible, the defense must not only prove that the accused was not at the scene of the crime at the time of its commission, but it must also prove that it was absolutely impossible for the accused to be there at that time.
