Florida attorneys have filed a lawsuit against Harvard University and its medical school after federal investigators said the institution’s morgue was at the center of a nationwide scheme in which body parts from donated cadavers were bought and sold.

The litigation was filed Wednesday in Suffolk County Superior Court in Boston, Massachusetts on behalf of three families whose deceased loved ones, all of whom died within the last six years, donated their bodies to Harvard for medical research.

The deceased — identified in the complaint as Glenn Wilder Sr., Marshall Jolotta and Joseph Gagne — could have been among those whose remains were pilfered and shipped across the country as part of a macabre black market, the lawsuit alleges.

Harvard morgue cadaver scheme:Grisly indictment details shipped human skin, an embalmed brain

The morgue’s former manager, 55-year-old Cedric Lodge, was fired in May from Harvard amid the federal investigation. Lodge, along with his 63-year-old wife Denise Lodge, was among those indicted earlier this month in a U.S. District Court with conspiracy and interstate transport of stolen goods.

Federal investigators tied to the scheme to tens of thousands of dollars and numerous types of human body parts that were exchanged over the course of several years from Harvard Medical School’s morgue and an Arkansas mortuary.

Lodge is accused of using his position to allow customers into the morgue itself to shop among the cadavers and select the body parts — bones, skin, dissected heads and brains— they wished to purchase. Lodge and his wife are then accused of preparing those remains for sale and shipment through the mail from their home in Goffstown, New Hampshire, according to the indictment.

Attorneys with the law firm Morgan & Morgan in Orlando who filed the lawsuit said in a statement provided to USA TODAY that they’re seeking to “fight to hold everyone responsible for this disgrace accountable.”

“When these individuals and their families made the generous and selfless decision to donate their bodies, they trusted their remains would be treated with utmost care, dignity, and respect and that their donations would be used to educate the future generation of doctors and ease the suffering of others,” according to the statement attributed to Morgan & Morgan attorneys John Morgan and Kathryn Barnett. “Now, these families are left to relive the trauma of losing their loved ones and wonder what happened to their remains.”

Morgan and Barnett are representing the families in the litigation along with attorneys Ryan Lang and Garrett Lee.
