THE party where missing teen Kiely Rodni was last seen was compared to "Lord of the Flies" by a close friend, who alleged it was "full of illegal activity".
Kiely's friend, Sami Smith, shared footage from the Friday night party, which took place in the public woodland area surrounding the campsite.
The video shows dozens of teens gathered on the land surrounded by trees, with trash strewn around, including what appear to be empty bottles of alcohol.
In another scene, a group of youngsters are seen partying while a light from a cell phone is shining on them.
The community has been hosting teen-to-teen talks without adults, including law enforcement, in an effort to get them to come forward with any relevant information about Kiely's disappearance.
Sami told The U.S. Sun: "I think a lot of them were scared to talk, they were engaging in illegal activity in the woods, it's like this Lord of the Flies space where they can just be.
"We've said over and over again, we're not investigating any of you, we're partnering with you in an investigation for a missing person, this isn't about things you shouldn't have done.
"But it's also hard because there are so many teenagers, what are their relationships like with their parents? That can define a lot of what they're going to say. Are they used to hiding everything?
"They're afraid of the consequences or how they're going to be viewed, how their parents are going to react. But at this point, it's like, who cares? We need to find her."
The Sun also understands that the teens were sometimes “fighting” during the evening, and smoking weed as well as drinking alcohol.

“We do not have any new leads and that is very frustrating to us,” Lt. Barnhart from Placer County Sheriff's Office said during a press conference on Wednesday afternoon.
Law enforcement have now had more than 300 tips, but nothing solid to suggest what may have happened to Kiely.
The FBI brought in around 50 personnel to help with the search and officers have been knocking on doors and reviewing CCTV from stores, gas stations, and other businesses, along with Ring camera footage from residents' homes.
So far, police say nobody has come forward to say they saw her leave the party.
Lt. Barnhart added he thinks someone knows something and is not coming forward.
Kiely's phone has been off since 12.30am Saturday morning, police also said Wednesday.
The teen had an iPad, which is at her family home, and her laptop is believed to have been in her car, which is still missing.
Police have searched with dirt bikes, helicopters, and on foot and have found no evidence that Kiely went anywhere near her home.
An Amber Alert has not been issued as authorities say Kiely's case does not yet meet the criteria.
The latest updates come just hours after detectives revealed a photo of Kiely captured on surveillance footage.
She had been spotted on August 5 at 6.08pm before she went missing.
Kiely was wearing a black spaghetti strap bodysuit, green Dickies pants with a black grommet belt, along with a pair of black Vans.
'IT FEELS SURREAL'
Kiely's mother, Lindsey Rodni-Nieman, said she knew her daughter was going to party in the woods but wasn’t concerned.
“There have been parties there every weekend for years," she told The U.S. Sun.
"It feels like a safe spot. It’s a campground, [with] paved roads, they can sleep overnight if they want to.
“This community feels very safe … this kind of thing does not happen here. It feels surreal."
These statements follow a video message Lindsey had posted on Facebook pleading for the public's help to locate her daughter.
"We just want her home. We're so scared, and we miss her so much, and we love her so much.
"And Kiely, we love you, and if you see this, please just come home," the emotional mother said, fighting back tears.
"I want nothing more than to hug you.
"And if anybody else out there if you know where she is, if you know anything about where she might be, if you have any ideas or thoughts, please come forward and share them."
SEARCH RAMPED UP
On Tuesday, a group of divers was called in to search a 90-foot dam at Prosser Creek Reservoir, about an hour away from Lake Tahoe, as the search for the missing teen ramped up.
Volunteers met at the local recreation center, where her family is staying in a camper, and dozens more joined throughout the day.
One loved one was heard saying: “We're gonna find her, we are gonna find her, we're not to be f***ed with here.”
Personnel from the Hasty Team were on scene at the 760-acre reservoir - a sub-group from Washoe County Sheriff’s Office which specializes in diving.
They traveled from Reno and were by the reservoir on Tuesday around 9.50am.
The Placer County Sheriff's Office is not ruling out the possibility Kiely could have been abducted as her SUV also vanished.
Officials are searching for Kiely's 2013 Honda CRV, which has a California license plate of 8YUR127.
Kiely is described as standing at 5 feet, 7 inches, and weighing 115 pounds with blonde hair and hazel eyes.
The 16-year-old also has numerous piercings and a nose ring.
