I learned a couple of hours ago that my (step)father died suddenly of a massive stroke this morning. I'm still in shock, not feeling anything clear yet. What happens next isn't going to be known for a while--my parents were getting ready to board a plane in London to come home from a trip. At least one of my sisters is going to London tonight.
Update: My mother called my sister this morning and said he was dead, but that turns out to have been premature. When they took him off the ventilator he didn't immediately die (as the doctor had predicted). Apparently it is just a matter of hours while the blood seeps down into the brain stem.
Further update: He died peacefully about 8:15 pm eastern U.S. time, one in the morning there.
