A public defender left a hearing in a Cook County courtroom Tuesday bogged down with an overstuffed accordion file folder and stacks of papers.

It was LaFonzo Palmer's first day representing John Granat, 18, in the case against him and three other teens for the armed robbery and beating death of a Granat's parents, a Palos Township couple.

Palmer didn't comment on the ongoing case and now joins the attorneys of the other three suspects, Mohammad Salahat, 18, Christopher Wyma, 18, and Ehab Qasem, 20. The four accused appeared in bright yellow Department of Corrections garb in Judge Neil Linehan's Bridgeview courtroom on Tuesday.

Wyma and Granat both had private attorneys withdraw from the case; it was not immediately clear during Thursday's hearing who Wyma's new attorney is or when he joined the case. Qasem is represented by John J. Eannace.

Meanwhile, Salahat's attorney Joel Brodsky is moving forward with two motions—one claiming that Salahat can not be tried for murder because he was 16 when he was arrested and another asking for a reduced bond. All four defendants were denied bail after they were arrested in September 2011 and have remained in custody.

Wyma's attorney said he has to review Brodsky's motion—as Wyma was 17 during the time of the crime—to determine whether he will join it.

Brodsky also told Linehan that he gave prosecutors copies of a psychiatric evaluation of Salahat conducted while he was in jail. The doctor who gave the evaluation may testify at the next hearing, Brodsky said.

The four are set to be back in Linehan's court at 10:30 a.m. on Oct. 5.
