Parris was one of the original accusers during the trials in 1692, and her accusations led to the arrest and eventual execution of several innocent people. However, after the hysteria surrounding the trials died down, Parris appears to have disappeared from historical record.
It is possible that she may have returned to her family's home in Boston after the trials, or she may have moved away from the area entirely. Some historians have speculated that she may have suffered from some form of mental illness, which could explain both her accusations during the trials and her subsequent disappearance from history.
Regardless of what happened to her, Betty Parris remains an important figure in American history as a reminder of the dark side of human nature and the dangers of mass hysteria.
