MIAMI AP – Officers fighting networks of indoor marijuana factories took out what they called a major operation Wednesday in a secluded back room of a house where a nice older lady sold ice cream to kids.

The raid targeted a sophisticated pot-growing operation that could net more than $300,000 a year, authorities said. The woman, Juana Betancourt, sat drinking coffee, appearing calmly resigned to the bust, as local police and federal agents carted away the crop. She wouldn’t comment.
