Peterson was convicted earlier this month of killing his third wife Kathleen Savio.
The former Bolingbrook sergeant appeared in court Tuesday with attorney Joel Brodsky. Brodsky asked Judge Edward Burmila for more time because "new issues have come up." Those issues include a bitter feud among defense team members.
On Monday, attorney Steve Greenberg, who was fired after the guilty verdict, accused Brodsky of single handedly losing the trial.
The judge told Brodsky to make his request in writing and scheduled another hearing for October 18.
