There is a lot missing from the story that is clearly known, and intentionally held back.
What was the cause of death?
Did ‘they’ contract it before, or after or during the party (was ‘they’ the main event)?
Were there any co-morbidities?
Was ‘they’ given treatments such as HCQ?
Etc...
The cause of death was COVID-19. Please refer to the Fox News link I posted.
