The motive for this crime is represented by the ten of wands, reversed. So we have another upside down "ten"! This card tells of lawsuits and duplicity, and also of legal losses. This was on the minds of the persons who committed the murder, and was part of the general picture. There was a threat, somehow, somewhere; presented to the material well-being of a family by the presence of Terell. Strength appears in the environment.....this murder was committed by persons who honestly felt that what they were doing was right. Also, the public perception of the perpetrators is one of "they would never be involved in a crime", so the investigation stalled, partly because law enforcement was looking for known violent criminals rather than sleuthing through Tirell's affairs in search of a motive. In the place of hopes and fears, the Page of Swords reversed comes up. We have an accessory after the fact who knows who murdered Tirell and why. This person was young enough to be one of Tirell's peers in 1976. The final outcome is the nine of pentacles, reversed. This speaks of a loss of friendship or a loss of a home. It would appear that the murder did not truly protect the Queen of Cups and the Emperor, after all.
It really looks as if this murder was committed by two people, a man and a woman; and it also looks as if they knew Tirell, and planned the murder in advance. It was done to protect a family's resources or reputation, and the perpetrators got away with it because no thorough investigation was performed, examining all links to Tirell, her life, and her future.
