It may not be one of the Ten Commandments, but it kind of goes without saying that thou shalt not cook meth in a house of worship.

But two women were accused of cooking meth inside a rural southern Illinois church on Wednesday, the Associated Press reports.

Judith Hemken, 53, and Tiffany Burton, 26, were arrested near Hillsboro after a Waveland Hillsboro Presbyterian Church member "noticed activity" in the building on a Tuesday night when it was supposed to be empty, Montgomery County Undersheriff Rick Robbins told the The State Journal-Register. The church member reportedly spotted one woman outside the church and another in its basement, with what appeared to be parts of a meth lab.

The women fled in a car, but were pulled over by police. Officers found a clandestine lab in the church basement and had to extinguish a small fire that started due to the lithium and moisture from a sink drain, the Journal-News reports.
