Won’t know much till her med/drug/psych/disease/vax history is known and an autopsy is done.
But dang it all...too many of these xlnt athletes just dying. Way more than I ever remember. Really needs a complete analysis including the mRNA vax, and biochemical analysis and histological analysis of heart tissue.
Unfortunately, that's not going to happen.
Remember when there were autopsies and follow up articles? That has been curiously rare the last couple of years. As a school system employee in England, it is a guarantee she was required to get the jab.
