The Whole Event, In One Killmail
The record contains one loss and nothing else: no supporting kills, no structure losses, no capital or supercapital on the list. Two participants appear in the killmails. The Marshal's recorded price is an individual loss value, not an aggregate of several hulls, so the 13.7B ISK figure belongs to this ship alone. Whatever else was happening in JQU-KY at the time, the evidence covers only this one hull leaving the field.
Nobody Credited With the Shot
The killmail identifies the victim and the organisation that lost the ship, but supplies no final-blow pilot and no final-blow organisation, and it names no attacker organisations at all. So the record shows the loss without showing who is owed the credit - a gap rather than a story about ambush, escalation or escape. One confirmed killmail proves one ship died; it does not prove anything about what the other pilot did afterwards, or whether anyone else was on grid at all. Goonswarm is down a Marshal, and the record stops there.
