Axel Herzsprung, who was another co-owner of ACMB-American Corporation for Milling and Boreworks, also said Laukamp didn't own this papyrus and didn't collect antiquities.
Additionally, since the investigation was published, Live Science has been in contact with an agency in Berlin that issues permits for the exportation of antiquities. Representatives of that agency said they could find no record that a papyrus like this had been exported from their office. It's possible that the Gospel of Jesus's Wife papyrus was exported from elsewhere in Germany or from the European Union.
Just recently, Christian Askeland, a research associate with the Institut für Septuaginta-und biblische Textforschung in Wuppertal Germany, revealed new information that casts further doubt on the papyrus' authenticity. His work is set to be published in the journal Tyndale Bulletin and is currently posted on a blog.
Askeland analyzed a second papyrus that, according to documents published in the Harvard Theological Review, was also purchased by the anonymous owner from Laukamp. It was presented to Harvard as a papyrus believed to be genuine.
This second papyrus, which has writing on two sides, includes text from the Gospel of John — and is a fake, writes Askeland, its lines being copied from a papyrus published in 1924. In addition, the researcher notes this papyrus has similar handwriting and ink to the Gospel of Jesus's Wife, making it likely that the Jesus's wife papyrus is also fake.

This second papyrus, which was carbon dated to between the seventh and ninth centuries A.D., is very similar to a Gospel of John papyrus, written and published by Egyptologist Sir Herbert Thompson in 1924, Askeland noted. In fact, the line breaks (the places where the text begins) are identical to those from Thompson's text. This is illustrated in an image of one side of the papyrus alongside Thompson’s 1924 text posted by Mark Goodacre of Duke University on his blog and republished on Live Science.
