The body of missing teen Kiely Rodni was in a vehicle found submerged in a California lake this week, authorities confirmed Tuesday.
"The Nevada County Sheriff-Coroner has identified the decedent as 16-year-old Kiely Rodni, of Truckee," the Placer County Sheriff's Office announced on Facebook.
"The Placer County Sheriff’s Office and the Nevada County Sheriff’s Office are in communication with Kiely’s family and offer our deepest condolences to them during this extremely difficult time."
Rodni's cause and manner of death have not been released, and the sheriff's office says the investigation is ongoing.
Rodni vanished on Aug. 6 after she attended a party at Prosser Family Campground in an area known as “The Sanctuary” in Truckee.
Authorities said Sunday night that a vehicle containing human remains was found in Prosser Lake, near where the party was held. Nevada County Sheriff Shannan Moon said at a news conference Monday that the remains are "more than likely" Rodni’s. An autopsy was scheduled for Tuesday.
"We have located a decedent inside the vehicle. We believe it is our missing person," Moon said Monday, adding at the time that investigators had not yet positively identified the body.
"But it’s more than likely where we are today," Moon said.
Rodni had been at an outdoor party with more than 100 other teenagers before she disappeared. Her cellphone last transmitted information around 12:30 a.m. Aug. 6.
Authorities searched an 80-mile radius looking for her. Her vehicle, a 2013 Honda CR-V, was found in 14 feet of water, about 55 feet from shore, by Adventures With Purpose, a private collective of divers who had been assisting in the search.
Doug Bishop of Adventures With Purpose said Monday that the discovery, about 300 yards from the campground, was made with the help of sonar imaging technology.
Rodni’s family thanked law enforcement, volunteers and everyone else who helped support them in a statement Monday.
"While we accept this sadness cast under death’s shadow, the rising sun shines light upon us, reminding us not to mourn our loss, but to celebrate Kiely’s spirit and the gift that we all received in knowing her," her family said. "Kiely will surely remain with us even though we will not get her back."
