I spoke with Ernie Santiago last nite and he was not aware of anything regarding Pellius, but did mention a couple of Hawaii BB related deaths due to Covid.
He also mentioned that the big gyms on Oahu now belong to B.J. Penn who may be able to provide further information providing that GetBigger can call with accurate info such as Pellius' full name and date of death.
I only made a call to 24 Hr Fitness with negative results, but I tend to think that one of the B.J. Penn gyms was more likely to be the choice of Pellius.
PS.... I have not read the majority of these posts, so I may be out of date regarding these matters.
