Paris Hilton might want to reevaluate the invite list before her next house party.
Los Angeles Police detectives investigating last month's $2 million jewel heist from the hotel heiress' mansion believe the burglar had a good grasp of the floor plans, knowing exactly where Hilton hid her valuables, prompting speculation it may have been an inside job.
Echoing what Hilton told E! News, investigators are going over evidence and narrowing their search down to a number of unidentified aquaintances of Hilton, per the Los Angeles Times.
The perp entered through an unlocked door sometime between the evening hours of Dec. 19 and 4 a.m. the next morning and immediately located Hilton's secret stash of baubbles—which included necklaces, watches, rings and some family heirlooms.
Security camera footage showed a person dressed in a hoodie and wearing gloves.
An LAPD spokeswoman declined to comment this morning on the Times report, citing the ongoing investigation.
The Simple Lifer's security detail discovered the theft at approximately 5 a.m. and called the cops. Hilton, who was partying on the night of the break-in, later told E! News that she has since given police a list of people whom she thinks might be behind it.
"You know, it's just an invasion of privacy, and it's happened to me before," she said. "It's really scary but they're doing a huge investigation on this, and we're going to catch this person."
She also urged the buglar to return the jewelry anonmyously by having a taxi deliver it in a box to her house so "they won't get in trouble." But she warned that if they didn't do the right thing, "they're going to get in more trouble."
