A former manager of Harvard Medical School's morgue is facing federal charges for allegedly stealing, selling, and shipping human remains.

Ex-employee Cedric Lodge and his wife Denise worked together to sell heads, brains, skin, and bones as part of an underground network.

US Correspondent Dan Mitchinson says that the parts were sold online, including body parts of two stillborn infants.

He says sometimes you can't get the answer as to why people do what they do.

Students at Harvard use donated bodies to practise medical procedures.
