Four members of a Florida family were convicted Wednesday of selling a toxic industrial bleach as a fake Covid-19 cure through their online church.

A federal jury in Miami found Mark Grenon, 65, and his sons, 37-year-old Jonathan, 35-year-old Joseph and 29-year-old Jordan, guilty of conspiring to defraud the United States and deliver misbranded drugs, according to court records. That charge carries up to five years in prison. Their sentencing is scheduled for Oct. 6.

Prosecutors called the Grenons “con men” and “snake-oil salesmen” and said the Bradenton family’s Genesis II Church of Health and Healing sold $1 million worth of their so-called Miracle Mineral Solution. In videos, it was pitched as a cure for 95% of known diseases, including Covid-19, Alzheimer’s, autism, brain cancer, HIV/AIDS and multiple sclerosis, prosecutors said.
