What really happens when bodies are donated to science?

In 2013, Tom Hayes' body was donated to a for-profit body donation service. “I just assumed that they were going to do what they were supposed to do – take the body, donate it to a school and just be the go-between of people learning from his body,” said his wife, Linda Hayes, who thought his body would stay whole before being cremated and returned to her. Instead, his body – and many others – may have been dissected and distributed multiple places. The company later came under scrutiny by the FBI as part of a fraud investigation. Linda Hayes got a box of ashes back, but she's not sure they belong to her husband.
