Unfortunately, this is only a small example of the due process violations many noncitizens have faced. Those who don’t believe immigrants should be afforded due process, how do you feel about the US citizens that have been accidentally and wrongfully deported? Skipping steps like this, is the reason mistakes like that happen.
News Release: Former GCSO Detention Officer Charged with 20 Counts of Felony Forgery
Sheriff Danny H. Rogers reports that on Friday, September 11, 2026, at approximately 8:00 a.m., the Guilford County Magistrate’s Office notified the Guilford County Sheriff’s Office (GCSO) of a potentially forged court document submitted by GCSO Detention Officer Michael Diehl.
The document, entitled “Order After Receipt of ICE Detainer and Administrative Warrant”, an AOC-CR-662 form, was associated with an Immigration and Customs Enforcement (ICE) detainer issued for inmate Claudio Nepornuceno. Upon review, the Magistrate’s Office and GCSO Detention staff determined that the document contained the allegedly forged signature of a different magistrate who didn’t process Nepornuceno’s initial arrest.
Under North Carolina law, when certain inmates are subject to an ICE detainer, they must be presented before a magistrate with a copy of the ICE detainer. The magistrate may then issue an AOC-CR-662 form, which authorizes the Detention Center to hold the inmate for up to 48 hours beyond the time they would otherwise be entitled to release from custody. The 48-hour window allows ICE an opportunity to take custody of the inmate.
In this case, it was determined that Nepornuceno was not presented before the magistrate with the detainer. Instead, an AOC-CR-662 form containing the magistrate’s allegedly forged signature was submitted.
A further review of jail booking records identified 19 additional AOC-CR-662 forms associated with 19 additional inmates that contained allegedly forged signatures of magistrates.
At this early stage in the investigation, however, it appears that in each of these 20 cases, ICE had issued a detainer based on evidence that the inmate who was the subject of the detainer was in violation of United States immigration law.
The GCSO Major Crimes Investigative Unit initiated a criminal investigation. During the investigation, Diehl’s employment with the Guilford County Sheriff’s Office was terminated (Hire Date: 6/1/2008).
As a result of the investigation, 40-year-old Michael Shaun Diehl Jr. was arrested and charged with 20 counts of Felony Common Law Forgery. He received a $5,000 secured bond and has since been released from custody.
Because the investigation remains ongoing and because additional charges may be forthcoming, there is no further information to share at this time.
