Unfortunately, probably not. But that's probably because of a lack of data rather than any inherent limitation to astrology.
In my previous article on the death of Natasha Richardson, I only really scraped the surface of the various astrological warning signs that an attentive astrologer might have seen. There were, in fact, more... and the comments on that entry pointed out more techniques yet that indicated the possibility of physical hazard.
One lesson I learned from practicing the techniques outlined in The Astrology Of Death is that if you are going to die, and you are of great importance to someone... your death is going to register as an important event in their birth chart. Unfortunately, we don't have a time of birth for Natasha's husband, Liam Neeson. And without it, his transits at the time of his wife's tragic accident are surprisingly... bland.
Liam Neeson was born June 7, 1952 in Ballymena, Northern Ireland. Without a time of birth, his transits are hard to read. Of course, the ongoing Saturn-Uranus opposition has been squaring Liam's natal Sun-Mercury-Venus conjunction off and on for over a year now, which undoubtedly has made trouble for him in one department of his life or another. But in all my tabloid gossip reading (a professional hazard for astrology bloggers) I don't recall ever hearing of any marital trouble with Liam and Natasha Richardson. Certainly, given the connection between Venus and one's love life, it would be a natural area of inquiry for any astrologer doing a reading for Mr. Neeson.
What this all raises with me is not so much an astrological observation, but two philosophical questions:
1) Have you ever noticed how many times, when someone loses a loved one suddenly, the story goes like this:
"We had been arguing, and he/she (ran out, had to go, got a call on the other line)... and the next thing I knew, the police were at me door telling my he/she was gone..." ?
2) Is there someone you should be talking to today?
