The body of missing 16-year-old Kiely Rodni was pulled from a California reservoir on Sunday near a campground that she vanished from about two weeks ago, the Placer County Sheriff’s Office confirmed on Tuesday following an autopsy. 

Her remains were discovered inside a vehicle submerged in 14 feet of water on Sunday afternoon by Adventures With Purpose (AWP), a group with a popular YouTube channel that assists in missing persons cases.

AWP, which joined the search for Rodni last week, found her silver Honda CRV with her inside of it upside down in Prosser Creek Reservoir just 55 feet offshore on Sunday.

An autopsy on Tuesday confirmed that it was Rodni, but toxicology results could take four to six weeks.

Placer County Sheriff's Capt. Troy Sander said that the area had been "extensively searched," including by plane, helicopter, boat and divers. The water level had dropped three feet since Rodni's disappearance on Aug. 6.

Rodni's disappearance was initially considered a possible abduction due to the suspicious circumstances.
