Yes. Jordan Chandler was the child who was a "good" friend of Michael's. They had a great friendship, but his father, Evan Chandler seemed to get very jealous. He was a dentist, and had access to certain drugs, one of which he gave to his son, which he was under the influence of when Evan got the so-called confession out of him. It has been proven by medical specialists that people on this drug, cant remember the correct name, are extremel susceptible to any suggestions made to them. Evan was also recorded saying how he could and would destroy michael, and he didnt care how it would affect his son. He wanted the money more than he cared abot his son. (He recently tried to kill his son, Jordan. Not sure of the reality of that though..)
Since michael's passing,Jordan has come out and finally admitted it was all lies. It was all just to get money to avoid being poor. I have no opinion of Jordan, except that i'm glad he feels the guilt now. I hope it stays with him to HIS grave. I don't know what came of the father. He might be dead now.
Sorry for the unecessarily long answer, but this is an issue i can't answer short answers to.
Anyway, yes. And i believe he was the first. After this, other people realised they had something they could leech on, with something to back it up. It put ideas in other people's heads. I think it is the saddest past of Michael's life because it wasn't deserved. He explained so often but few would believe him :(
It's even sadder that he will never hear Jordan's apology.
