A former Detroit body broker, who was convicted of fraud related to the rental of diseased body parts, is expected to be decided in federal court Monday, May 21.

While the U.S. Attorney's Office is requesting that U.S. District Judge Paul D. Borman sentence 64-year-old Arthur Rathburn of Grosse Pointe Park to between 11 and 14 years in prison, Rathburn believes, based on sentencing guidelines, he should receive between six months and a year.

Since Rathburn has spent more than two years in prison awaiting trial and then sentencing, He could be released with time served, should Borman side with the defense.

Prosecutors are also asking the judge impose nearly $2.5 million in restitution.

Rathburn of Grosse Pointe Park and his ex-wife Elizabeth Rathburn were accused of operating a body broker business named International Biological Inc. (IBI) and fraudulently misrepresenting its unusual products -- human body parts -- between 1995 and 2013.

The business closed shortly after the FBI raided Rathburn's macabre Detroit warehouse in 2012.

Rathburn's former wife pleaded guilty to a count of aiding and abetting wire fraud, for which she was sentenced to two years probation.

Investigators testified to finding "piles of dead flies," with frozen clumps of heads, arms, legs, organs and torsos stored in paint cans, beer coolers and Tupperware throughout the warehouse.

While it was never mentioned by prosecutors during trial, Reuters published leaked photos that showed the FBI also seized fetuses during the raid of Rathburn's property.

The FBI and U.S. Attorney's Office has since refused to discuss, or even acknowledge, the fetuses were discovered.

Rathburn purchased diseased bodies at a discount and failed to disclose infections to customers -- usually medical training and product seminars -- according to federal investigators. Sepsis, HIV and hepatitis were among the infections U.S. attorneys say Rathburn failed to disclose.

Rathburn was found guilty of six counts of wire fraud, each punishable by up to 20 years in prison, and illegal transport of hazardous material.

Investigators say Rathburn, in addition to deceiving his customers, arranged to have infected heads air-freighted from Tel Aviv, Israel to the U.S.

The severed heads were wrapped in trash bags and piled into a camping cooler for delivery via Delta Cargo in February 2012.

Federal investigators said Rathburn lied to officials, claiming the heads had been embalmed, but testing revealed they were in a pool of bloody mixture found at the bottom of the cooler with Listerine mouth wash.

Defense attorneys for Rathburn, James C. Howarth and Craig A. Daly, argue that that victims in the case suffered no "actual loss" and that justifies a lighter sentence for their client.

"To date ... the government presented no proof that any of the individuals who received specimens from Rathburn incurred any actual loss," defense attorneys wrote in Rathburn's sentencing memorandum. "Instead, they all profited handsomely from the use of his specimens, collecting fees from the participants, increasing their professional standing and increasing the participants skills."
