NEW YORK (CBSNewYork) — A Scarsdale mother has been arraigned on charges she grew thousands of marijuana plants in a highly sophisticated marijuana growing operation out of a warehouse in Queens.

Andrea Sanderlin entered a plea of not guilty Friday in Brooklyn federal court.

The mother of two daughters, ages 13 and 3, Sanderlin, 45, lives in a beautiful home in a highly sought-after town. Her neighbors told CBS 2’s John Slattery they were stunned by the news.

“You would never think a 45-year-old woman would become involved, especially in this nice area,” said neighbor Linda Tibaldi.
