Simon L. Leis Jr. (/liːs/; born June 12, 1934[1]) is a lawyer and local official from Cincinnati, Ohio.
In 1971 Simon was appointed County Prosecutor to replace Melvin Reuger, who had resigned to become a judge.
Leis led two high-profile trials, both times earning a conviction, and both later overturned by appellate courts.
This second case was the basis for a 1996 movie, The People vs. Larry Flynt, in which his role was played by political operative James Carville.
Leis retired as Hamilton County Sheriff in 2012, and was succeeded by Jim Neil.
