TRUCKEE, Calif. - Authorities have received more than 900 tips related to 16-year-old Kiely Rodni's disappearance from a campground party one week ago in Truckee.
Kiely was last seen on Saturday near the Prosser Family Campground at a party attended by hundreds of juveniles and young adults, police said.
Kiely's phone has been out of service since the party, and her car, a 2013 silver Honda CRV, has not been found, authorities said.
Here's a timeline of events that have occurred since Kiely vanished:
Surveillance footage captures Kiely at a local business on Aug. 5 wearing a black bodysuit and Dickies pants roughly six hours before her disappearance.
Later that day, Kiely, an early high school graduate, attends an end-of-the-summer party with friends from high school near the Prosser Family Campground. Locals call the area "the campground."
The party escalates from a high-school event to a party of some 300 people ranging in age from teenagers to young adults and even some older adults, some of whom the teenage attendees were not familiar with. The party included drugs and alcohol, and officials are searching for video footage or photos of a possible fight that occurred that night.
Kiely's friend, Sami Smith, who was at the party with her, said that Kiely was planning to spend the night at the campground.
"I know that she wasn’t in the right mindset or state to drive. And if she were to have driven, she wouldn’t have made it far," Smith told a local news outlet.
Kiely texts her mother around 11:30 p.m. saying she is planning on leaving the campground around 12:15 a.m.
"I asked her to be safe," Kiely's mother, Lindsey Nieman-Rodni, told Fox News in an interview Friday, " … and that was the last time she texted me."
Kiely speaks with friends and family shortly after midnight, according to authorities.
Her phone turns off around 12:33 a.m. that morning. It last pinged near the Prosser family Campground within Tahoe National Forest before it turns off, Placer County Officials said.
The 16-year-old's family lives about 10 miles away from the campground at a lodge south of town.
Kiely is reported missing, and the Placer County Sheriff's Office shares a notice regarding her disappearance later that day. The Sheriff's Office also reported that Kiely's vehicle, a 2013 silver Honda CRV with the with California license plate "8YUR127," is missing.
The Placer County Sheriff's Office establishes a tip line for information leading to Kiely's whereabouts.
Officials also begin a massive search for the missing 16-year-old near the Prosser Family Campground. The Placer County Sheriff’s Office says they are investigating a possible abduction because the girl’s SUV was also unaccounted for.
The sheriff's office did later clarify that they are investigating the teen's disappearance as a missing person case.
Detectives follow up on leads and continue to search the campground area with a Falcon 30 Helicopter. Multiple law enforcement agencies from Northern California and Nevada, which borders the area, are involved in the search. The FBI is also involved.

The sheriff's office receives more than 100 tips related to Kiely's whereabouts but none that lead to her or her vehicle's location. There are 77 law enforcement personnel assigned to the case.
During a joint news briefing Wednesday afternoon, police from multiple agencies plead with more party attendees to come forward. They say they have received a large amount of video from the party but no clues that have led them to Kiely's whereabouts.
The search now includes several aircraft, including helicopters and airplanes flying in formation above, dive teams, and all-terrain vehicles, including four-wheelers, trikes and dirt bikes. There are search dogs present and at least 100 members of law enforcement visible, including members of the FBI, who initially focused their attention on Campsite 4.
In a joint statement, the Placer County and Nevada County Sheriff's Office say they have assigned 265 personnel to the case. The number of tips received climbs to more than 300, tripling Tuesday's total.
Investigators say they have still not recovered any items they believe belong to Kiely and they are still searching for witnesses who saw Kiely physically leave the campground party.
The FBI lists Kiely as a missing person and releases a poster sharing information about the 16-year-old.
The Placer County Sheriff's Office announces that it has activated the CodeRed Emergency Alert System.
"We have about an 80% enrollment for Nevada County, so out of our 100,000 residents, that message should hit about 80,000 residents," Nevada County Sheriff’s Office Capt. Sam Brown says of the CodeRed alert during a Thursday afternoon press conference.
Authorities display the latest known photo of Kiely, taken about a month prior to her disappearance, showing her distinctive gold jewelry.
More than 220 law enforcement personnel have been assigned to the search, and officials have received more than 500 tips from across the country related to the case. Other countries have also offered assistance in finding Kiely.
