This is going around Coronado:
On Tuesday night/Wednesday morning that RN died, "some time after midnight" JS left DS (at hospital) to "go for coffee" and didn't return "for about an hour."
They had already been told that MS would not survive his injuries.
DISCLAIMER: I used to live in Coronado, this was told to me by someone who still does live there, and while questioning that person, I learned this information was 3rd hand from "the family." Which family? My source didn't know. Said "family" views JS with suspicion.
It's like playing telephone. Any one of the points above may be totally incorrect, but it's all I've been able to glean (that is not already known.)
