Why do people kill? In the case of the young and mentally unstable Frank Zastera, the rationale was as simple as the act was brutal: he wanted William Sheppard’s money. In other homicides, such as the still-unsolved 1913 murder of George Harris, the motive for committing the ultimate crime remains obscured for eternity. In Murders in Monmouth, author George Joynson unflinchingly assembles the who, what, when, where and why surrounding twelve high-profile killings perpetrated by various individuals in early twentieth-century Monmouth County.
