Three-Way Sex Witness Said R. Kelly Employee Threatened Her, Documents Show

Documents unsealed from the R. Kelly child pornography trial include claims from the prosecution's star witness that an employee of the R&B star threatened her.

Lisa Van Allen says the employee told her last year she should've been killed for coming forward with information that could damage Kelly. No one was charged with threatening Van Allen.

Van Allen testified she had three-way sex several times with Kelly and the female who prosecutors say was the victim in the sex tape at the center of the trial.

Van Allen says in the pretrial statement she stole a separate video tape of one of those encounters from Kelly's duffel bag.

Jurors acquitted Kelly last week of child pornography. The documents were unsealed Tuesday.
