Joseph Force Crater was an American lawyer who served as a New York State Supreme Court Justice and mysteriously vanished shortly after the state began an investigation into corruption in New York City. Despite massive publicity, the missing persons case was never solved and was officially closed forty years after Crater was declared dead.

A presumption of death occurs when a person is believed to be dead, despite the absence of direct proof of the person's death, such as the finding of remains attributable to that person. Such a presumption is typically made by an individual when a person has been missing for an extended period and in the absence of any evidence that person is still alive—or after a shorter period, but where the circumstances surrounding a person's disappearance overwhelmingly support the belief that the person is dead. The presumption becomes certainty if the person has not been located for a period of time that has exceeded their probable life span, such as in the case of Amelia Earhart or Jack the Ripper.
