OJ Simpson 14 years later?

I know someone cannot be tried for the same crime twice. But has anyone tried to re-open the Simpson/Goldman file to find more evidance pointing to Simpson or another individual. Meaning with all the advancements in DNA in the last 14 years, do you think if they tested everything again, would the results be the same. I guess my real question is anyone trying to find the real killer, if infact, its not Simpson? For the record, I think he is very guilty.
