so after the shooting of bill ewell's friend, bill ewell decides to take another look at ruben cantu.by now, juan moreno had twice failed to identify ruben cantu as the shooter. with ruben in custody, ewell sent a detective to juan's home. >> i took the photos, the forms and a portable typewriter. i showed juan this array. he sat there and looked at them and looked at them and looked at them and he shoved them aside and looked away from them. he said, look i know who did it. i know who shot me. so why do i have to identify anyone out of this photo array. i said, well, who did it? he said, ruben cantu. we went around and around. i could tell the guy was very scared. he didn't want to sign anything. i think that he was afraid of retaliation. he just would not do it. so i folded up my typewriter and bid farewell. >> it didn't make any sense to me that juan moreno supposedly saw ruben cantu face to face, inches apart when he was shot, they showed him at least five or more photo line-ups with ruben cantu in these line-ups. he still couldn't identify him. why is he not being identified? >>
