Hi, all.  Phil had wondered if anyone knew what caused Dean Jackson's death.
I just went to Jonathan Mosen's site, and here's a blurb I found:

It's been a while, but the Mosen explosion radio Show returns after a month
away with celebration.
The first part of the show celebrates the life of Dean Jackson, who was
suddenly taken from us last week when, after a spate of epileptic seizures
in recent times, a seizure tragically and unexpectedly took his life.
