MADISON, Ind. (WDRB) -- An employee at a southern Indiana power plant thought it was a prop or Halloween decoration when he made a disturbing discovery in the Ohio River on Friday morning.

“He found what looked to be part of a human leg,” said Cliff Carnes, the plant manager at Clifty Creek Power Plant in Madison. “Everyone was questioning, are you sure it’s not a mannequin or some type of prank?”

The unusual find led workers at Clifty Creek to call Madison Police and the Jefferson County Coroner.

"We responded and did indeed find a left lower leg below the knee,” said Coroner Johnny Collins.

According to Collins, the foot was wearing a gray, size 10.5 New Balance tennis shoe and a black sock.

Cadaver dogs searched the area and found no additional remains, but Collins says they did stumble across something else of interest.

“We did find a complete suit of clothing that involved blue jeans, a t-shirt, and a hoodie,” Collins said. “They were entangled in a root system of trees in opposite sides of the creek. The clothing and the leg were found approximately less than 1,000 yards apart."

The clothing was collected but Collins says it's still unclear if there is a connection.

The leg has been taken to the University of Indianapolis where an anthropologist will work to determine an approximate age, gender, and race.

That information could be released later this week, Collins says.

DNA from the limb will also be added to the National Missing and Unidentified Persons System in the hopes of finding a match.

“I do suspect that it came from somewhere east of Madison,” Collins said.

Anyone with information on the case is asked to contact the Jefferson County Coroner’s Office at (812) 599-1893 or the Madison Police Department at (812) 265-3347.
