Earlier quoted context omitted.
I am not a lawyer, but @klasfeldreports on twitter quotes an unnamed legal source who says: "Background: An important note after Epstein's death: no one else will have standing to challenge the search warrant on his house. Everything will be admissible against any other defendant without possibility of a motion to suppress." So maybe this will be a net good for justice?
But his death also ends the criminal case against him, no one else was charged in the indictment. Why act on a warrant for a case that has ended? I’m definitely not an expert in criminal justice proceedings though.
If there were related parallel investigations, they could either still be before a grand jury, not yet have been submitted to a grand jury, or already had indictments issued but under seal. The fact that no one else was charged in the Epstein indictment does not mean there is no one else in a related matter against whom an investigation and/or (sealed) charges exist, which, if from no other source, the public coverage of all the investigations around Trump should have made everyone familiar with recently.
