The Chandler boy had an unusual relationship with his father, his father hit him over the head with a 12-and-a-half-pound weight, sprayed him with Mace and tried to choke him. As a result he got a restraining order against his father. This was when he was 26 and the two were still living together.
The Chandlers were trying to get $20 million out of Jackson and the father hated Jackson. As to whether the boy was abused by Jackson, as he was by his father, is clearly in doubt.

It is unclear whether the description given of Jackson's penis was accurate or not.
Jackson's insurers paid the Chandlers $22 million, apparently against Jackson's wishes.
Incidentally a large number of male pop stars have had sex with underage groupies. R Kelly, who wrote songs for Jackson, was convicted of filming sex he had a 14-year-old. This generally doesn't cost them many fans; in the case of King (who had sex with 14 and 15 year old boys) I guess the problem for society was that they were boys rather than girls.
