The infamous Salem witch trials, which took place in colonial Massachusetts between 1692 and 1693, were a dark period in America's legal history. More than 200 people were wrongfully accused of practicing witchcraft, and 20 were executed. In the 328 years since, most of the accused have been cleared of any crimes. However, for reasons unknown, Elizabeth Johnson Jr., who was just 22 at the time, was never pardoned. Now, thanks to the hard work of an eighth-grade class from North Andover Middle School, MA, her name may finally be cleared.
