feels responsible for her death and resigns from the DA's office. He is succeeded by Jack McCoy (Sam Waterston) as Executive ADA. Post-departure Stone is mentioned in the 1996 episode "Custody" as a possible witness against a judge. When his former assistant Paul Robinette, now a defense attorney, wants a judge to recuse himself for past comments showing bias against drug addicts and support for forced sterilization, Robinette threatens to subpoena Stone to testify about the comments, which both he and Stone heard the judge make. Upon hearing of the threat, Schiff informs McCoy that Stone "is traveling in Europe, not available to testify at any hearing."
