I don’t think the skateboarder guy (Grosso) died, or had his death attributed to, coronavirus. Was that reported anywhere?
He was at home. He was dancing vigorously with his son the day before his death.
No, and he wasn't a big star.
He had attempted suicide several times, and "died suddenly" is sometimes used as a euphemism for suicide, particularly in obituaries. If there's no cause of death listed, and the term "died suddenly" is used, often a suicide or murder disguised as a suicide.
