you say his mums his alibi, but on the frontline documentary when asked "have you ever asked luke if he killed jodi" she didnt once say "no because he was with me at the time" she answered "I didnt have to because a mother can just tell", it wouldn't be a case of motherly instinct helping you decide your son was innocent if you were with him at the time and knew for a fact it couldnt have been him, it wouldnt be left to motherly instinct to base ur opinion on. corinne messed up there. that was her chance to tell every one it couldnt have been him, luke was with her, nope she didnt mention it once.
