Mercer was accused of the murder of Mahlon Hutchinson Heberton aboard the Philadelphia-Camden ferry vessel John Finch on February 10, 1843. Heberton had seduced (or raped - sources differ upon this point), Mercer's sixteen-year-old sister. Mercer entered a plea of insanity and was found not guilty. The trial took place only two months after Edgar Allan Poe's short story "The Tell-Tale Heart," a story based on other murder trials employing the insanity defense; Mercer's defense attorney openly acknowledged the "object of ridicule" which an insanity defense had become.

He advertised it as "A Popular Journal, devoted to such matters of Literature and news as will interest the great mass of readers". Its first issue was published December 30, 1848. Social reformer In 1850 Lippard founded the Brotherhood of the Union (later the Brotherhood of America), a secret benevolent society aiming to eliminate poverty and crime by removing the social ills causing them. His own title in the organization was "Supreme Washington". His legend-like vision was that such an organization would establish a means for men to sincerely follow a
