“DO NOT PUBLISH – Former first lady Barbara Bush d*es at age 92 DO NOT PUBLISH.”
That was a mock up, in preparation for the actual announcement. It is not unusual for media outlets to pre-write these kinds of obits to be ready at a moment's notice.
In my first book, I had discussed these kinds of jumping the gun obits -- but in this case, it is more than obvious that this was a dress rehearsal revealed too soon rather than an actual misreporting.
It's still a creepy thing to see, though...
