Oh so sad. This article has a little more info about where he was found (BBM):
"The teen's family hired a private investigator to look into their son's disappearance. The investigator looked at the last place the phone was pinged, near the lakeside of Arbor Place Mall, despite police having already searched that area, Andrew said.
The investigator went further toward the direction,
where Andrew said the PI discovered a "concrete structure" that resembled a well. That's when the investigator found Yaron's body inside, in what his dad described as a 50-foot structure.
"It's where the waters go before they are released into the storm drain," Andrew said. "He was found at the bottom, he was found at the bottom of that concrete structure."
Yaron Kathuri, 17, was found dead on Saturday, more than three weeks after he vanished.
