A self-described “human blood artist” from Pennsylvania who was busted for peddling body parts — some belonging to children — has pleaded guilty in federal court to trafficking in human remains.

Jeremy Pauley, 41, of Enola, was initially arrested and charged with abuse of a corpse, receiving stolen property and dealing in proceeds of unlawful activities.

During a Friday appearance in US District Court in Scranton, Pauley admitted to his role in a nationwide network of people who bought and sold human remains stolen from Harvard Medical School and an Arkansas mortuary.

He entered his guilty plea before U.S. District Court Judge Matthew W. Brann to conspiracy and interstate transportation of stolen property.

Pauley — a body modification artist whose face is covered with tattoos and whose head is decorated with metal spikes — posted pictures of bags and piles of femurs, vertebrae, clavicles, ribs and human teeth for sale on his now-deleted Facebook page.

The Facebook page Pauley used to market his body parts is called “The Grand Wunderkammer,” which uses the descriptor, “Vendors of the odd and unusual, museum exhibits, guest lectures, live entertainment, and so much more! Strange, curious, and unique in every way possible!”

Pauley told police he was a collector of “oddities,” and claimed the remains were purchased legally, according to authorities. Cops initially found what they described as older human remains including full skeletons that they determined were lawfully obtained.

However, after a second tip about newer remains in Pauley’s home, investigators returned to the house to find more recent purchases.

Police found three five-gallon buckets containing assorted body parts, including two brains, human skin and fat, a heart, a kidney, livers, lungs, a trachea and a child’s mandible with teeth, according to a criminal complaint cited by Fox 43.

Federal and state law enforcement agents later intercepted packages addressed to Pauley from an Arkansas woman, Candace Scott, that allegedly contained body parts.

Pauley told investigators he intended to resell the body parts, according to the affidavit. Investigators allege Pauley arranged to pay Scott $4,000 for the body parts — including half a human head — through Facebook Messenger.

Scott and five others have been charged along with Pauley and are pending trial, the US Attorney’s office said.
