Under the deal, Magoon, 50, pleaded guilty to one count of manufacturing methamphetamine and received five years of probation. The case was heard earlier this month.
Charges were dropped against his younger brother, Matthew Magoon.
On March 10, police went to the home in the 800 block of Angela Street to serve an arrest warrant on Matthew Magoon on unrelated charges. There, they uncovered evidence of a clandestine drug lab used to make methamphetamine. During the investigation, police turned up evidence that included glassware, beakers, propane tanks, tubing, acetone, salts, powders, smoking devices, precursor for making methamphetamine, a digital scale and packaging.
Department of Justice Bureau of Narcotic Enforcement agents also went to the home to investigate and dismantle the lab, police said. Livermore-Pleasanton Fire Department hazardous material crews went to the home as a precaution.
