A man has been arrested on federal charges for allegedly using a forged signature of Chief Justice John Roberts to attempt to dismiss his criminal case. Court documents reveal that Joshua M. Culver, also known as ‘Maverick A. Young,’ was taken into custody in Colorado last Friday, following an indictment by a federal grand jury in Indiana.
Culver faces four counts of falsely impersonating a U.S. officer or employee, and one count involving the use of a forged judge’s signature and court seal. Prosecutors claim that he filed a document titled ‘Order of Dismissal With Prejudice’ on September 24, 2025, in Grant County Superior Court, Indiana.
The document allegedly contained a forged signature of Chief Justice Roberts and a counterfeit U.S. Supreme Court seal, used to authenticate the dismissal order.
This is not Culver’s first attempt to impersonate a federal official, authorities say. Just five days before the forgery incident, Culver allegedly posed as a National Security Agency (NSA) agent, contacting the Tippecanoe County Sheriff’s Office. He is accused of using his fake authority as an NSA agent to request actions that would not normally be fulfilled.
Among these actions were a welfare check on his biological daughter and obtaining information about her location. Culver also allegedly sought details on sheriff’s office employees, asserting he could take ‘adverse action’ against the department in his supposed NSA role.
The following day, prosecutors allege Culver called the workplace of an ‘Individual A,’ falsely claiming to be a federal agent and accusing the person of obstructing an investigation. He allegedly threatened the individual’s arrest and requested employer intervention for cooperation.
In January 2026, Culver reportedly impersonated a ‘Special Master enforcing orders of the United States Supreme Court.’ He is accused of communicating with the Lake County clerk and Superior Court judge, claiming authority to issue orders and demanding various actions.
These included changing vital records and dismissing judgments against him. Culver allegedly warned of arrests for non-compliance, asserting that he and U.S. Marshals would enforce federal law.
In February, Culver supposedly adopted another federal identity, this time as ‘Director of Tailored Access Operations.’ Prosecutors say he filed a directive in Lake County Superior Court, demanding dismissal of his case, quashing warrants, and cooperation in a ‘federal audit.’
Bloomberg Law reported Culver’s arrest on August 21, with the Office of the Federal Public Defender for the District of Colorado appointed for his representation.
Fox News has contacted the Supreme Court’s Public Information Office and other relevant agencies for comment.
