Michael Carvin and Eric Murphy don’t know Jennifer McCann very well, and they don’t have much in common with her career-wise. Carvin is a well-known U.S. Supreme Court advocate at Jones Day, and Murphy is one of his proteges at the firm. McCann, on the other hand, is a young solo criminal defense lawyer in Long Island best known for her vigorous and at times controversial representation of Levi Aron, who confessed to a gruesome murder-kidnapping in Brooklyn last summer.

But in 2010, the unlikely trio of lawyers briefly joined forces. In a closely-watched case before the U.S. Court of Appeals for the Second Circuit, they argued that a pharmaceutical sales representative named Alfred Caronia had been wrongfully convicted of conspiring to misbrand a prescription drug—a misdemeanor offense under the Food Drug and Cosmetic Act.
