DETROIT – A father and son from Chicago have been charged in Michigan as part of an investigation into diseased body parts sold on the black market for research.

The Associated Press reports Donald Greene Sr. has been charged with wire fraud and his son, Donald Greene II, has been charged with knowing about the scheme but failing to report it.
