Execution? Execution? Heavens he will not be even be convicted much less executed. Be realistic, this is America 2007 A.D. He will write a book, tour the talk show circuit, there will even be a movie of his struggles. He will make millions, run for office and be elected. He will retire with multiple generous pensions. Then full of years and honors ascend into heaven. There will be those who believe that he will return with our Lord and help judge the quick and the dead.(At least if one believes the forgiveness freaks.)
I was going under the assumption that the newspaper reports quoted elsewhere that he has confessed, according to the local sheriff.
