Police set up a sting to bust an Indianapolis man accused of stealing the brains of dead mental patients and selling them on eBay, the Indianapolis Star reported.

Authorities said 21-year-old David Charles broke into the Indiana Medical History Museum multiple times this year to steal jars of human brain tissue and other preserved items, the Indianapolis Star reported.

The museum is located at the site of the former Central State Hospital, which treated psychiatric patients from 1848 to 1994. The organ tissues Charles stole come from about 2,000 patients whose remains were autopsied from about the 1890s through the 1940s.

One of Charles' buyers who paid more than $600 for six jars of human brain tissue helped bring the "organ entrepreneurism" to an end. The buyer called the museum after noticing labels on the containers and "suspecting some kind of skullduggery" and he later tipped off authorities, the Indianapolis Star reported citing court documents.

Detectives of the Indianapolis Metropolitan Police Department traced the transactions and spoke to the seller, the middleman, who claimed to have gotten he brain matter from Charles.

The Indianapolis Star reported that Police set up a sting Dec. 16. As a part of the sting, eBay middleman set up a meeting at a Dairy Queen parking lot with Charles, who the day before stole 60 jars of human tissue from the museum, according to authorities and court documents.

Authorities moved in to arrest Charles after the transaction as made.

Charles is charged with theft, marijuana possession and drug paraphernalia possession, and prosecutors said he could face additional charges, the Indianapolis Star reported.

Additional charges may be added, A.J. Deer, a spokesman for the Marion County prosecutor's office told the USA Today.

It's not clear whether anyone else will be charged in the case.

The museum's executive director expressed shock and disappointment that anyone would steal the museum's artifacts.

"It's horrid anytime a museum collection is robbed," Mary Ellen Hennessey Nottage told the Indianapolis Star. "A museum's mission is to hold these materials as cultural and scientific objects in the public interest. To have that disturbed - to have that broken - is extraordinarily disturbing to those of us in the museum field."

Much of the stolen material has been returned, the Indianapolis Star reported.
