Meth Lab Found Beneath Walmart Parking Lot Cops believe it was an active operation By Arden Dier, Newser Staff Posted Aug 9, 2016 12:21 PM CDT 41 comments Comments Gotta love sewer meth. (Shutterstock) (Newser) – Police officers stumbled upon a meth lab in an unlikely spot Monday: a sewer beneath a Walmart parking lot in a Buffalo suburb. Authorities say officers discovered the lab, which is believed to have still been active, on a routine patrol in Amherst, per the Buffalo News. Officials in hazmat suits eventually removed aerosol spray cans, chemicals, plastic bottles, and suspected methamphetamine from the sewer, which was tall enough to stand up in, reports WIVB. No suspects were found, though police plan to review surveillance footage. A resident says the discovery is "unbelievable" for the area.
