Three months after a Florida man and his three sons were convicted of selling toxic industrial bleach as a fake COVID-19 cure through their online church, a federal judge in Miami sentenced them to serve prison time.

Jonathan Grenon, 37, and Jordan Grenon, 29, were sentenced on Friday to 151 months in prison for conspiring to defraud the United States by distributing an unapproved and misbranded drug, and for contempt of court, according to a news release from the U.S. Attorney’s Office Southern District of Florida. Mark Grenon, 66, and Joseph Grenon, 36, were sentenced to 60 months in prison, the statutory maximm for conspiring to defraud the United States by distributing an unapproved and misbranded drug.

All four had been found guilty by a federal judge this summer after a two-day trial where the Grenons represented themselves, according to The Miami Herald. Mark Grenon is the father of Jonathan, Jordan and Joseph Grenon.
