(REUTERS) — WASHINGTON  Federal agents discovered four preserved fetuses in the Detroit warehouse of a man who sold human body parts, confidential photographs reviewed by Reuters show.

The fetuses were found during a December 2013 raid of businessman Arthur Rathburn’s warehouse. The fetuses, which appear to have been in their second trimester, were submerged in a liquid that included human brain tissue.

Rathburn, a former body broker, is accused of defrauding customers by sending them diseased body parts.
