In an email to The New York Times, he said his ring preyed on the dead, the unsuspecting and the elderly, especially those from Florida and California, using birth certificates and other documents to discover personal information that aided in their schemes.

'We figure out how to steal', he said. 'That's what we do'.

Recently, the writer suggested, the group had turned its attention to a major target: the estate of Lisa Marie Presley , which last week faced a threat that Graceland was about to be foreclosed on and sold by a mysterious company, Naussany Investments & Private Lending LLC.

Media outlets often receive unsolicited emails from people who make outlandish claims. But this email arrived in response to one sent by the Times to an email address that Naussany listed in a legal filing sent to a Tennessee court reviewing the foreclosure case.

In its email, the Times referred to the company's claim that Presley had borrowed $US3.8 million from it, using Graceland as collateral. In the responses, which came from the email address the Times had written to, the writer described the foreclosure effort not as a legitimate attempt to collect on a debt, but as a scam.

'If this had not been such a high-profile piece of property, they might have gotten away with it'.

Mark Sunderman, real estate professor: 'I had fun figuring this one out and it didn't succeed very well', the email writer said. He said he was based in Nigeria, and his email was written in Luganda, a Bantu language spoken in Uganda. But the filing with the email address was faxed from a toll-free number designed to serve North America; it was included in documents sent to the Chancery Court in Shelby County, Tennessee, where the foreclosure case is still pending.

Since the news broke last week that a company was trying to sell Graceland – Elvis Presley's former home and a beloved tourist attraction in Memphis – the Naussany company has been a persistent puzzle. It is difficult to find any public records that prove that the company exists. Phone numbers listed in court documents for the company are not in service. Addresses listed by the company are those of post offices.

In September, eight months after Lisa Marie Presley's death, Naussany Investments did file papers in probate court in California posting what it said was Presley's debt from 2018. It included a deed of trust, with a signature represented as Presley's, that put forward Graceland as collateral.

But Clint Anderson, the deputy administrator of the Shelby County Register of Deeds, said his office does not have on file a deed of trust or any other documents from Naussany Investments 'to legitimise this company foreclosing on any other property in Shelby County'.

In its September filing, Naussany Investments said it would agree to settle what it described as the debt for a discounted $US2.85 million, which would be paid by the Presley family trust. But the trust, now led by Lisa Marie Presley's daughter, actress Riley Keough, did not view the debt as legitimate.

Naussany Investments then took out an ad in Memphis newspaper The Commercial Appeal, giving notice that it planned to auction Graceland in a foreclosure sale last week.

That led Keough to court last week, where she fought the foreclosure, declaring in a legal filing that the loan was a fiction, the company 'a false entity' and the effort to sell Graceland a fraud. The signatures of Presley and of a notary public on some of the documents had been forged, lawyers for Keough said.

A judge blocked any immediate foreclosure on Graceland, saying that he needed to review more evidence.

No one representing the Naussany company attended the hearing. But shortly before it began, the court received a filing from a person identifying himself as a representative of the company, Gregory E. Naussany. The filing disputed Keough's allegations, asked for time to present a defence and included an email address, This email address is being protected from spambots.

By the end of the day, though, Naussany Investments appeared to have given up. The Commercial Appeal and the Associated Press reported receiving emails from the company withdrawing its claims. Elvis Presley Enterprises, which operates Graceland as a tourist attraction, told the Times that a lawyer for the family's trust had also received an email from a person purporting to be Gregory Naussany who said Naussany Investments did not intend to move forward with a sale.

Court records, however, do not yet list any motion by Naussany Investments to drop its claim.

In a bizarre case with so many unanswered questions, it is difficult to determine how much weight to place on the recent communications to the Times from the email address associated with Naussany Investments. While the writer said he is based in Nigeria, it is difficult to pinpoint his location.

Naussany Investments has listed several email addresses in its court filings. Both emails received by the Times in recent days came from the address associated with Gregory Naussany that was listed in the company's court filing. In each, the writer advanced the view that he was
