Prosecution rests in R. Kelly trial

CHICAGO, June 2 (UPI) -- Prosecutors in R. Kelly's child pornography trial in Chicago rested their case Monday but not before the defense tried to impugn the motive of a key witness.

The R&B singer is charged with videotaping himself having sex with an underage girl some time between 1998 and 2000. Kelly's attorneys maintain the female on the tape isn't who prosecutors say she is and the man having sex with her isn't Kelly.

But Lisa Van Allen, 27, testified about three sexual encounters she allegedly had with Kelly and the alleged victim, and also identified Kelly and the girl in the video, the Chicago Tribune reported.

Defense attorney Sam Adam Sr. brought out the fact that Allen waited years before coming forward, and that her fiance and a former boyfriend were convicted of federal fraud charges.

"What, do you have some thing where guys have to have some federal fraud charge before you are interested in them?" Adam asked.

Kelly's lawyers are expected to start presenting their case Wednesday, a day after Chicago Sun-Times music critic Jim DeRogatis is to be questioned by the defense.

DeRogatis is the person who gave police the sex tape at the core of the case, the Tribune said.
