The Watertown PD asked the Wisconsin Department of Justice-Division of Criminal Investigation (DCI) and the U.S. Drug Enforcement Administration for help in dealing with the lab.
The clandestine lab was discovered when the Watertown Police responded to a report of a domestic disturbance at a single family home.
While investigating the domestic disturbance, the officer found materials inside of the home that led the officer to believe that the materials may part of a clandestine lab.
The occupants of the home were evacuated and at least one person from the home was detained.
Agents from DCI, a chemist from the Wisconsin Department of Justice's Crime Laboratory, along with clandestine lab technicians from the Drug Enforcement Administration and the Milwaukee Police Department processed and examined the contents of the lab.
During the processing of the lab, some of the residents in the immediate area of the residence were evacuated for several hours due to the explosive potential of volatile chemicals.
