I dont know that he did it, i am willing to admit there is a chance it was someone else, you cant admit it could have been him though can you? you cant admit jodi set off to meet Luke, something happened and he killed her, Lukes brother doesnt even remember seeing him in the house n apparently he burned his dinner. sure. Massive inconsistancy there in the alibi, but when some members of the search party change minor details in their statements, youl latch on to it for years.
ps I believe Willie Gage is innocent, thats as far as you need to read into my username choice.
