A woman’s body was found in the Des Plaines River in Channahon Saturday, police said.
The identity of the woman is currently being withheld, but police are investigating.
Police scoured the waters last month after Charles McCullum confessed to dumping his mother’s body in the river, right across from the Joliet police station.
Police have charged McCullum, 21, with first-degree murder after allegedly confessing to choking and stabbing his mother, 54-year-old Jeannie Parker last Thursday, and dumping her body in the river.
Crews had problems navigating underwater because of murky conditions. Sonar equipment was later brought in to aid in the search.
McCullum remained in custody, held on $5 million bond.
"We just want the physical body so we can have closure. We know she's in heaven, we know she's there," said Parker’s sister-in-law, Lovett Williams.
