From that series of articles, during Le Roux's court hearing:

> Le Roux admitted that he had created the encryption software E4M but denied that he had developed TrueCrypt, its famous progeny.

Also:

> Hafner and his SecurStar colleagues suspected that Le Roux was part of the TrueCrypt collective but couldn’t prove it. Indeed, even today the question of who launched the software remains unanswered. “The origin of TrueCrypt has always been very mysterious,” says Matthew Green, a computer-science professor at the Johns Hopkins Information Security Institute and an expert on TrueCrypt who led a security audit of the software in 2014. “It was written by anonymous folks; it could have been Paul Le Roux writing under an assumed name, or it could have been someone completely different.”

The developers of E4M and of VeraCrypt are known; the developers of TrueCrypt are not fully known.
