(Reuters) - A Michigan woman pleaded guilty on Monday to a scheme in which she and her husband used their medical cadaver business to sell infected body parts to unwitting medical and dental students, prosecutors said. Elizabeth Rathburn, 56, of the Detroit suburb of Grosse Point Park admitted selling human remains she claimed were disease-free, but which had tested positive for HIV and Hepatitis B, the U.S. Attorney’s Office in eastern Michigan said in a statement. ​ 
 
 Arthur Rathburn faces charges of wire fraud, aiding and abetting and making false statements. Prosecutors said Rathburn and her husband, Arthur Rathburn, ran a company called International Biological, Inc. that would sell or rent human remains to medical and dental students.
– A Detroit woman faces up to 10 months in prison for fraud after admitting to renting diseased body parts to researchers. Elizabeth Rathburn, 56—to be sentenced in July—also must pay $55,225 to the American Anesthesiology Association, whose researchers were told the body parts were clean, reports the Detroit Free Press. But her estranged husband, Arthur Rathburn, 62, could face more than 20 years in prison if convicted of charges related to his work as a cadaver dealer. The trade of body parts "is not, in and of itself, illegal," but "crimes have been committed," an FBI agent says in an affidavit. Under the Rathburns' company International Biological Inc., Arthur Rathburn is accused of purchasing discounted body parts infected with HIV and hepatitis B, then renting them to unsuspecting customers who could have been exposed to infection, per the Detroit News. Arthur Rathburn worked with the University of Michigan's anatomical donation program for six years until he was fired for selling bodies in 1990. He then worked as a private dealer. Prosecutors say he cut up bodies with chainsaws "without using sanitary precautions," and kept more than 1,000 body parts at a warehouse. He's also accused of selling bodies for $5,000 on the black market. Heads were allegedly sold for $500, while arms fetched $750. In one instance, prosecutors say he shipped fresh heads—which reportedly sat in pools of blood inside coolers—on a commercial plane. Rathburn faces charges including wire fraud, making false statements, and transporting hazardous materials at trial on April 5, per Reuters. His wife "will assist the government with any knowledge that she has," her lawyer says. "Her life has been ruined largely in part because of her association with Mr. Rathburn."
