Is joran Van Der Sloot innocent?

I am hearing conflicts that don't add up in this latest Joran Van der Sloot accusation
1. some broadcasters say he must have raped Stephanie Ramirez
2. the Peruvian officials said there was no evidence of a rape or sexual assault
3. the casino setting indicates he may have indeed murdered her for her winnings; how else has he been supporting himself?
4 he comes from a good background had many opportunities
5 I think he is unscrupulous
