Astrological indicators of post-death recognition?

1
What transits or Solar Arcs would you be likely to see to a person's natal chart when long after their death they are recognised in some way?

I am especially curious about people who have disappeared, presumed murdered. What would be the astrological indicators of their body being found or what happened to them being discovered, or even being found alive?

I am tentatively wondering if an astrologer should be looking at the Moon's Nodes in the person's natal chart, and transits and arcs to it?
