Murder conviction without a body

It is possible to convict someone of murder without the purported victim's body in evidence; however, cases of this type have historically been hard to prove, often forcing the prosecution to rely on circumstantial evidence, and in England there was for centuries a mistaken view that in the absence of a body a killer could not be tried for murder. Developments in forensic science in recent decades have made it more likely that a murder conviction can be obtained even if a body has not been found. In some such cases, the resurfacing of the victim in a live state has ensured the re-trial and acquittal, or pardon, of the alleged culprit, including posthumously, such as the case of the Campden Wonder or the case of William Jackson Marion.
