Though she died unexpectedly in her sleep over a month ago, no cause of death for 17-year-old Gwen Casten has yet been disclosed. As reported by America’s Frontline News at the time, the death was being investigated by the DuPage County Coroner. 

Gwen’s father, Rep. Sean Casten (D-IL), has been a major proponent of the vaccine, calling the unvaccinated “knuckleheads” in September and telling Business Insider that every member of his staff got the shots “because they don’t like to be dead.”  

“I’ve made a point of not hiring knuckleheads, and everybody on our staff got vaccinated…” he said. 

In August, Casten asserted that anyone in a position of power who does not push vaccines and masks does not value life. 

"If you're not vaccinated, get vaccinated," he tweeted. “If you can't get vaccinated, wear a mask. If ANYONE in a position of power says anything to the contrary, they do not value your life.” 

Casten also expressed his gratitude for the shot when he contracted COVID-19 in January.  

“I’m grateful for the miraculous work of our scientists and health care workers — and encourage everyone to get vaccinated, boosted, and mask up,” Casten said.  

Gwen, who was active in her father’s campaign, was known to tweet fierce support for the vaccine and facemasks. 

In October, Gwen replied to a tweet from California Gavin Newsom announcing a vaccine mandate for children. Gwen tagged Illinois Governor J.B. Pritzker and wrote, “Can we be next please.” 

Rep. Casten’s campaign did not respond to Americas Frontline News’ request for comment. 

The untimely death came amid news media reports of an alarming rise in deaths among young, healthy people. News outlets say the deaths are flummoxing doctors, who are calling the phenomenon Sudden Adult Death Syndrome (SADS) and are starting “SADS registries” to discover the cause of the deaths. 

Dr. Peter McCullough, the most published cardiologist in the world, was one of those physicians who publicly warned against the COVID-19 injection, stating that the risks of the vaccine outweigh its benefits. 

On Sunday, Dr. McCullough suggested that deaths like Gwen Casten’s - and other “SADS” deaths – are following a certain formula produced by mass formation psychosis. 

“How to diagnose a death in mass formation: 1) death not expected 2) no cause of death given 3) no family/team/organization outrage 4) flowery nonspecific eulogy 5) no mention of when it was taken how many of them and when was last one (brand). 6) no X-rays labs or autopsy,” tweeted the world-renowned physician.
