Is there some succinct explanation for why Murray's reporting facilitated 'jigsaw identification' while other reports did not? I don't want a link to a 50 page court ruling, I want someone to explain it in a couple of sentences. Something like: Murray did not name Victim X but he specified the occupation of their spouse, the department they worked in, and their level of seniority. Given this information, a simple query of public records would be sufficient to identify this individual.
