Wearing a red jumpsuit, Corie Walsh, 40, was briefly brought into the Will County courtroom Monday before being escorted back out, NBC 5 reporter Regina Waldroup said. Her family and supporters filled the first two rows of the courtroom for the short hearing, with another pretrial court date set for next month.

In September, Walsh pleaded not guilty to first degree-murder charges, with her attorneys saying she was suffering from a psychotic episode at the time of the killing. She was ordered to remain detained, with Walsh's attorney Monday saying her team of lawyers was  learning everything [they] can about her psychosis. 

 Psychosis is not a choice,  Walsh's attorney, Andrea Lyon, said during a press conference following Monday's hearing. Lyon went on to say that the death of Walsh's 2-year-old Barrett, whose nickname was  Little Bear,  was an  unimaginable tragedy. 

 We are committed with our head, our heart, and hard work, to represent her to the best of our ability so that everyone can understand what happened here,  Lyon said.

Lyon added that Monday's hearing was routine, with the case waiting on more subpoenas.

 We are getting prepared to defend her, and that requires us to know everything,  Lyon said.  The only way to do that is to get all the discovery. 

Lawyers for Walsh added that her current psychosis condition remains  pretty overwhelming. 

 We're working closely with the jail to make sure Corey is treated fairly,  attorney Robert Kerr said.

Lyon said Walsh's family is  fully supporting her,  including her husband.  But he has to work. 

Another pretrial court date was set for Nov. 23.
