(Thursday, May 13, 1993, 8 p.m. EDT) — Krusty is out of a job when a new show featuring ventriloquist Arthur Crandall and his dummy, Gabbo, hits the airwaves and shrinks Krusty’s television ratings on tonight’s episode of the TV series The Simpsons.

(Monday, May 13, 1963) — The U.S. Supreme Court, in Brady v. Maryland, upheld today, 7-2, a lower court decision overturning the death sentence (but not the conviction) of John L. Brady for murder because the prosecution had withheld from the defense a statement by a separately tried accomplice, Charles D. Boblit, that he’d actually carried out the 1958 killing of William Brooks during a robbery.
Brady spent years in prison in legal limbo, declining his right to another sentencing hearing; he was eventually paroled. Boblit, 79, remains imprisoned in Maryland.
