TYLER ó A setback for a defendant in the so-called Mineola child sex ring case. Tylerís 12th Court of Appeals has denied an appeal by Dennis Boyd Pittman. Earlier reports said Pittmanís lawyer thought the outcome of the case would have been different if the court had allowed the showing of taped interviews of the children in the case. According to KETK, Pittman was convicted of engaging in organized criminal activity. He was sentenced to life in prison.
