The river usually gives back what it takes, in time.

"The remains of James Hutchinson and Nylo Lattimore remain missing in the months that have followed their deaths. Hutchinson, 6, was killed in Preble County in late February and later thrown into the Ohio River from the Carroll Cropper Bridge, weighed down by a concrete block, according to investigative and court records.
Just weeks before, 3-year-old Lattimore was thrown alive into the Ohio River in Cincinnati in December 2020 by his mother’s boyfriend. The man, identified as Desean Brown, 21, is accused of killing Nylo’s mother, 21-year-old Nyteisha just hours before Brown threw Nylo into the river, investigators previously said.
“The Ohio River is now a huge, unmarked grave that no one can go visit. We cannot put flowers at it. No one can leave James’ favorite toys at it. It is a grave that no one to this day has been able to find,” Lundy said."
