"It was horrifying," Prugo said. "I was really genuinely scared and Rachel's just like going back and forth in the rooms, grabbing clothes for herself and, you know, all this stuff and, I'm just like, 'Can we go?' Like, 'Let's go,' Like, 'Someone's going to come home.'"
Prugo says the pair made a haul.
"I think that's what, you know, led to so many more," Prugo said. "It's because this first time we did this, we found $8,000 in cash. That's a lot of money."
Officer Brett Goodkin of the Los Angeles Police Department said the burglars kept a list of targets.
"These kids knew what they were going to get every time they went in," Goodkin said. "And they had lists, they wanted this and they want that, they wanted that painting, they wanted that watch, they wanted these shoes in that size. And that's what they took."
The Hilton burglary was just the beginning, according to Prugo.
Prugo said the pair committed a burglary "whenever we run out of money or, or if Rachel wanted a new outfit."
Suddenly, Prugo said, more people wanted in on the action, including Diana Tamayo, Alexis Neiers and Courtney Ames.
In the following months, police said, celebrity targets of the "Bling Ring" would include Lohan, Patridge, Bilson, Bloom, Fox and Green.
"When you consider that it's not just a matter of them as a group stealing things, and then, you know, selling some of it and pocketing the money, and the thrill," said Goodkin, "that they're taking people's clothing, you know, even undergarments, and they wear them -- when you consider the surveillance, it's difficult to overlook at the end of the day just how creepy it is."
Police estimated that from October 2008 to August 2009, the "Bling Ring" stole more than $3 million in jewelry and high-end designer brands.
"There are a lot of things about it that suggest addiction, addiction to stealing, obsession, desperation," said Vanity Fair's Sales. "There's a desperate quality to it."
Police said the group began to sell what they stole through a suspect, Johnny Ajar, and others.
Prugo said the seriousness of what they were doing hit him when news station KTLA aired video of the Patridge burglary. "I mean, it was on KTLA and it was all on the news stations, this video," Prugo said. "And they are running me and Rachel, and you are watching this on TV and you are, like, 'Someone is going to recognize you. Oh, my God.'"
Police say the Lohan video helped them crack the case.
"It was quite evident that at least two of the people in the Lohan video we had seen before," said Goodkin. "And a couple of us had recalled where we had seen it, and it was the Patridge video. And that was our first indication that, hey, you know, something's going on here."
Investigators began visiting social networking Web sites to link the suspects.
"It allowed us early on to kind of create kind of a flow chart of, you know, who is this person, they clearly know each other because they've 'friended' each other," Goodkin said.
Prugo and Lee's alleged bragging about their capers at parties was helpful, Goodkin said.
"The fact [that] they bragged about it constantly," he said. "The fact that they didn't know when to give it up. They didn't have that discipline."
Prugo was arrested Sept. 17, 2009. He initially denied any wrongdoing, but eventually he started talking. Police said he gave them a tale they never expected.
