COLLIER COUNTY, Fla.- The Collier County Sheriff's Office has identified the 16-year-old who was found dead in a pond Saturday as Christian Castaldo, from Golden Gate.

A spokesperson for the sheriff's office told WINK News a person spotted the teen Saturday around 7:30 a.m. He was found in the pond area of the Island Walk community.

A couple out for a walk that morning spotted Castaldo floating in the pond. They notified a neighbor, who went into the water and pulled the teen's body out. His mother identified the clothes as her son's, according to deputies.

It's unclear how he died. Investigators are waiting on autopsy results.
