Samuel D. Parker (attorney)

[9] Kneeland's 1838 conviction was the last time a court in the United States jailed a defendant for blasphemy.

[10] In 1842, Parker was the prosecutor in Commonwealth v. Hunt, a case which ruled that labor unions were legal.

[12] In 1846 he prosecuted Albert Tirrell for the murder of Maria Bickford, a prostitute he left his wife to be with.

[14] On November 30, 1849, a group of men, including City Marshal Francis Tukey, Henry Jacob Bigelow, Parkman Blake, Robert G. Shaw, and members of the Boston Police Department came to Parker's home to inform him that human remains had been found.

The body was determined to be that of George Parkman and Harvard Medical School professor John White Webster was arrested for his murder.
