MIAMI, Okla. – An Illinois man who has received a mental health examination in connection with an alleged plot to attack dozens of northeastern Oklahoma churches with Molotov cocktails will be back in court next month.

Ottawa County Assistant District Attorney Becky Baird said Thursday that 23-year-old Gregory Arthur Weiler II of Elk Grove Village will return to court on Jan. 8 for a hearing that will determine whether he is mentally competent to go to trial.

Weiler is charged with threatening to use an explosive or incendiary device and violating Oklahoma's Antiterrorism Act. He was arrested in October after police say they discovered a plan to bomb area churches.
