Members of a Florida family who for years touted an industrial bleach mixture as a miracle cure for a variety of health conditions, including COVID-19, were found guilty of federal crimes Wednesday in Miami.

Mark Grenon, 65, and sons Jonathan, 37, Joseph, 35, and Jordan, 29, were convicted of conspiring to defraud the United States and deliver misbranded drugs after their church, the Genesis II Church of Health and Healing, sold $1 million worth of their so-called Miracle Mineral Solution, or MMS, according to court records.

The Grenons, who represented themselves and declined to speak or make opening statements during their two-day trial, were hit with the verdict after a jury deliberated for about 30 minutes, the Miami Herald reported .
