The Daily Herald has an article HERE which states in part that:

North Chicago police requested the help of the Libertyville fire department’s dive team in locating the weapon, which police said was used in a nonfatal shooting last week.

Fire department officials said the suspect was in custody, but police want to analyze the weapon to see if it was involved in any other shootings.

Shortly after 3PM on Weddnesday, Prospect Heights received a 9-1-1 call from a motorist who claimed to see two children in a pond near the Prospect Heights Public Works building in the 500 block of Piper Lane.

Several divers went into the water as did a boat with side-scan Kongsberg sonar capable of mapping the pond floor. There was some question as to exactly what was seen by the 9-1-1 caller, and after searching the pond for an hour and examining several images mapped by the sonar, the searches were terminated.
