David Coleman Headley had pleaded not guilty to charges that include conspiring to bomb public places in India and aiding and abetting the murder of American citizens killed during the attack that left 166 people dead. The court posted notice Tuesday that Headley will change his plea Thursday.
Headley attorney John Theis said Thursday's court action will reflect discussions between his client and federal prosecutors.
Authorities say the 49-year-old Headley also plotted to attack the newspaper because it published cartoons depicting the Prophet Muhammad in 2005. That attack never took place.
