A former employee of Discovery Bay Water Treatment Facility in California was indicted by a federal grand jury for intentionally attempting to cause malfunction to the facility’s safety and protection systems. Rambler Gallo, 53, was a full-time employee of a private Massachusetts company under contract with Discovery Bay to operate the town’s water treatment facility. He had an “instrumentation and control tech” role, which he fulfilled between July 2016 and December 2020.

The indictment alleges that Gallo had installed remote control software on his employer’s systems and also his personal computer, which enabled him to monitor instrumentation readings and control the electromechanical processes of the facility.
