A former employee at Ohio University admitted to stealing human remains from the school's anatomy lab, the Columbia Dispatch reported.

Former lab assistant Weston Henry Moquin, 28, pleaded guilty on Tuesday to stealing human bones from the university's College of Osteopathic Medicine lab and selling them to bone dealers between July 2011 and June 2012. An unsealed search warrant revealed that among the stolen remains were a fetus, two skulls and two shoulders, The Dispatch reported.

The stolen bones were from the university's teaching collection, according to Katie Quaranta, Ohio University's spokeswoman.

FBI special agent told the court that along with stole loose bones and skulls, Moquin also stole autopsy saws.

McBain said Moquin sold the bones mostly through his eBay account and had three frequent buyers: the Bone Room in Berkeley, Calif.; a Utah researcher and medical student; and a person in Oregon doing business as "Frozen Critters." McBain said each of the three purchased more than $5,000 worth of items from the former lab assistant.

Moquin was released on his own recognizance, but could be sentenced to 20 years in prison on "single counts of transporting stolen bones and preserved human remains across state boundaries and stealing property from a federally funded agency," The Dispatch reported.

A sentencing date has not been set.

The FBI began investigating Moquin after they were tipped off by a student employee who found a spreadsheet suggesting that Moquin had been selling human body parts.

Moquin's attorney, Keith Yeazel, told the Dispatch that his client sold the bones to support a drug habit.

Moquin reportedly told the U.S. District Judge Peter C. Economus that he has completed a 94-day drug-treatment program in California and is employed in the program. The Dispatch reported that Moquin's mother, Jean A. Reed, said her son has been off drugs for seven months.

A newsletter for the school's College of Osteopathic Medicine indicates that Moquin began work as an anatomical assistant at the university in May 2011. The university's spokeswoman Katie Quaranta told the Dispatch that Moquin worked at the university until September 2012.
