Three associates of Michael Jackson, including a reputed porn producer, have been cited as "uncharged co-conspirators" in the felony conspiracy case against the pop star, according to published reports.
ABC News and New York's Daily News report that Jackson financial advisers Dieter Wiesner and Ron Konitzer, and Mark Shaffel (who once made gay porn films) are named in the Jackson indictment, along with Vinnie Amen and Frank Tyson, two longtime Jackson aides who both worked at Neverland and were named by their own attorney as possible accused co-conspirators, according to earlier reports.
Amen and Tyson, who deny involvement, are being accused of holding Jackson's teen accuser, his mother and her other children against their will.
While not charged, Shaffel, Weisner and Konitzer reportedly are accused of conspiring with Jackson to abduct, falsely imprison and extort the accuser as a way of silencing his family.
Jackson, 45, has labeled all charges against him a "big lie" and pleaded not guilty on April 30 to charges of conspiring to commit child abduction, extortion and false imprisonment in a 10-count indictment handed down by a Santa Barbara County, Calif., grand jury. He also stands accused of committing lewd acts on a child under the age of 14 and plying the boy with an intoxicating substance (believed to be wine).
Jackson is next due in court May 28.
