Heroic dog update
No, I don't know anything further about Baron the German shepherd, but I do have more information about Nyals A. Andreason, thanks to a reader.
According to an online obituary, Nyals graduated from Brigham Young University and was a computer program analyst. He was active in the Church of Jesus Christ of Latter-day Saints and in 1983 married his wife, Judith, at the LDS Temple in Los Angeles. His survivors included a son, stepchildren, grandchildren, siblings and his father.
Now for the bizarre touch: Nyals died Dec. 11, 2006, a day after the 49th anniversary of the holdup in which Baron the dog was shot--and less than two weeks before the anniversary of the fatal holdup.
That's more than a bit spooky.
