Then this happened:
Locals are […] fearful [that Glenn] Sanders may have planted explosives in and around his wife’s grave at the nearby cemetery, the Herald Sun reported. […] Sanders was reportedly highly distressed by the loss of his wife, occasionally sleeping beside her grave. […] The coroner’s court heard that police moved in to arrest him over a false imprisonment incident that occurred the day before.
Sanders left his house through a rear door and approached police officers stationed within an armoured car. An explosion from within the house appeared to surprise Sanders, investigators said. He then exploded himself. Derrinallum residents have described Sanders as a nice man, although concerns were raised after he began walking through the town with explosives strapped to his chest.
