Police in Indiana used an uncover sting to catch a man who was selling stolen brains.
More than 60 jars of brain, and other human tissues, were stolen from a warehouse at the Indiana Medical History Museum in October.
Some specimens are over 100 years old.
Those jars wound up being listed on eBay.
A customer, who bought six jars for $600, got suspicious after he received them and alerted the museum.
That led undercover officers to set up a buy with the seller, at a local Dairy Queen.
Police arrested 21-year-old David Charles.
He is charged with felony theft and other charges.
He is due in court in Indianapolis this month.
The stolen jars of preserved human brain tissue are valued at about $4,800.
