The article was about volunteers from the Uvalde foundation coming to town to search for Caleb, which implies that it was not his body found in the well (obviously truthfully we don't know either way yet).
The article goes on to say, "City water employees were doing maintenance in the area on June 24 when they discovered human remains in a wastewater collection well, the
Corpus Christi Police Department said. The remains were too decomposed to identify, according to the Nueces County Medical Examiner’s Office."
Then, "Authorities aren’t sure how Harris’ body ended up in the well or how long it had been there", when the article just said the remains were too decomposed to identify. Oof is for bad reporting.
