A German man involved in the COVID-19 conspiracy community killed his wife and three daughters after his wife was caught with a fake vaccination card, police say.

German police say they believe a man, who has been referred to as Devid R., committed the quadruple murder-suicide last week. [I]n a suicide note, the man indicated the couple was worried that the government would take their kids away because his wife was found with a fake vaccination certificate he’d provided to her.

Like much of the rest of the world, Germany is in the midst of tightening up its regulations in light of the latest COVID variant of concern, Omicron. Residents are required to provide proof of vaccination to access some amenities, and some jobs also require their employees to be vaccinated. This was true of Devid’s wife, who was employed at a technical university. Her university noticed the fake vaccination card and asked her about it.

Local media reports that the punishment for faking a vaccination certificate is a year in prison or a fine and that authorities said Devid would have just been fined for providing her with the fake certificate.
