Why is there no documentary about this story?

The only one I could find is a 10 minute ''unsolved mystery'' short documentary.

Apart from the big main facts of the case there are so many details which make it truly interesting that we see in the movie but dont know to what extent they are accurate or not.

The relation between the kid and the kidnapers? how exactly did he party with them? did he really hook up with girls at the party? what happened to the dad of Jesse James Hollywood which was a drug dealer and secretly sent him money to Brazil? Did the kid older brother go crazy on the phone insulting Jesse James Hollywood while the guy initially was calling him to discuss and try to solve the matter? While they were driving him to the hills to kill him didnt the kid notice it was strange and what did he say to the three guys? etc.. etc.. etc...
