Two fetuses were shockingly discovered at a South Carolina water treatment facility earlier this month, authorities said.

WTAT-TV reported Tuesday that the fetuses were found in the water at the James Island wastewater treatment plant on Aug. 8. Officials said employees were doing routine checks when they made the disturbing find.

Charleston County Coroner Rae Wooten said the fetuses appeared to be mid-trimester and in “very early development,” according to the station. She said it was unclear how long the fetuses were in the water or whether they were related.

The mystery now turns to who flushed the fetuses down the drain and how it ended up at the facility.

Charleston Water Systems spokesperson Matt Brady told WTAT-TV that only things that are flushed or go down the drain end up in their system.

“Wastewater is an entirely different system from storm water and drinking water that you have at your taps,” Brady added.

Charleston police ask anyone with information about the flushed fetuses to contact Consolidated Dispatch at 843-743-7200.
