Testimony came to an abrupt close today in the R. Kelly trial as the defense was sought out by a man that could possibly discredit the prosecution's key witness.

According to The Chicago Tribune, the unidentified man will fly into Chicago tonight and meet with Kelly's defense team. Cook County Judge Vincent Gaughan said, "I have no idea what's going on. It might be the impeachment of the [prosecution's] witness."

Defense attorneys denied allegations that this was an attempt to delay the testimony of the prosecution's key witness, a woman who will likely testify she engaged in an under-aged three-way sex act years ago with Kelly and the alleged female on the tape.

Kelly's team said they were called by the mystery witness and they'd need time to meet with him in order to prepare.

Earlier today, Joel Rhea, a former teacher and basketball coach in Oak Park testified he met the alleged victim on the tape in 1997 since she played against his team.

He said the girl was best friends with one of his players and he'd see her at social events. Rhea said he identified the girl by her forehead, "Everyone gave her a hard time because she had a big forehead. We would joke about her forehead, that she had a big forehead."

As previously reported, yesterday a former Kelly employee identified both Kelly and the alleged victim as the participants in the tape. Linda Perryman said she recognized the girl because she'd frequent Kelly's studio and even saw her once with an overnight bag.

Kelly faces 14 counts of videotaping, producing or soliciting child pornography. He pled innocent to all charges and if convicted could face up to 15 years in prison.
