A federal contractor working for the Federal Aviation Administration was arrested and charged with threatening to kill President Donald Trump after prosecutors say he spent months researching assassination methods on a government computer before sending a direct threat to the White House.
Dean DelleChiaie, 35, of Nashua, New Hampshire, faces a charge of interstate communication of a threat against the president. The mechanical engineering contractor allegedly used his personal email account on April 21 to send a message to the White House identifying himself by name and stating his intent, Just the News reported.
The charge carries serious federal penalties and lands amid a string of recent criminal cases tied to threats against the president, raising sharp questions about how federal employees with security access are vetted and monitored.
The criminal complaint lays out a pattern of alleged premeditation stretching back months before the email was sent. Fox News reported that prosecutors allege DelleChiaie used his government work computer as early as late January to search for assassination-related topics, including how to smuggle a firearm into a federal facility and prior assassination attempts targeting Trump.
Prosecutors also allege he typed the words "I am going to kill Donald John Trump" on that same government computer, according to Newsmax.
Then, on April 21, DelleChiaie allegedly escalated from searches to action. Using a personal email account, he sent a message to the White House that identified him by name and made an explicit threat. The U.S. Attorney's Office quoted the email in its announcement. The Washington Examiner reported the language of the alleged threat:
"I, Dean DelleChiaie, am going neutralize/kill you, Donald John Trump."
A fuller version of the email, cited by Fox News prosecutors, went further, alleging a political motive:
"I, Dean DelleChiaie, am going neutralize/kill you, Donald John Trump, because you decided to kill kids, and say that it was War, when in reality, it is terrorism."
The Secret Service led the investigation into DelleChiaie, and he was arrested shortly after the email was sent.
One of the most striking details in the complaint is the alleged use of a taxpayer-funded work computer to research the mechanics of assassination. Federal prosecutors say DelleChiaie searched for information about how to bring a gun into a federal facility, details about the vice president's home and children, and specifics about prior attempts on Trump's life, AP News reported.
Those searches allegedly took place on an FAA system, meaning a federal agency's own network may have been used to plan or fantasize about harming the president. Investigators have not publicly confirmed whether any internal monitoring systems flagged the searches before the April email was sent, or whether FAA security protocols failed to detect them in real time.
DelleChiaie's role as a mechanical engineering contractor gave him access to federal systems and facilities. Authorities have not said whether he held a security clearance or had physical access to restricted areas beyond his normal work environment.
The arrest came just days after a separate, high-profile security incident near the president. AP News noted that DelleChiaie was taken into custody shortly after alleged gunman Cole Tomas Allen tried to storm the White House Correspondents' Association dinner, an incident that ended with a Secret Service officer being shot. That case drew national attention and prompted sharp commentary about whether the armed suspect had specifically targeted Trump.
The two cases are not alleged to be connected. But their proximity in time underscores a rising tempo of threats directed at the president that federal law enforcement is now confronting on multiple fronts.
DelleChiaie's case is far from the only recent prosecution involving threats against Trump. A Massachusetts man allegedly brandished a sword at FBI agents when they arrived to arrest him on separate Trump threat charges. That case illustrated the physical danger federal agents face even during routine enforcement of threat statutes.
Other threat prosecutions have taken unexpected turns. In one case, prosecutors dropped all charges against a librarian accused of recruiting assassins to kill Trump on social media, a decision that drew criticism from conservatives who questioned whether the Justice Department was treating threats against this president with sufficient seriousness.
The charge against DelleChiaie, interstate communication of a threat against the president, falls under federal statutes that criminalize threats transmitted across state lines. Prosecutors do not need to prove that a defendant had the actual ability to carry out the threat. They must show that the communication was transmitted, that it contained a true threat, and that the defendant acted knowingly.
The alleged internet searches on a government computer could serve as evidence of intent and premeditation if the case goes to trial. Prosecutors frequently use search history to demonstrate that a defendant's words were not idle talk but reflected genuine planning or fixation.
DelleChiaie has been charged but not convicted. He is presumed innocent under federal law. Investigators have not publicly said whether they recovered any weapons, travel plans, or additional communications beyond the email and computer searches described in the complaint.
The case raises uncomfortable questions about oversight within the federal workforce. The FAA employs thousands of contractors with access to government systems, and the allegation that one of them spent months researching assassination logistics on a work computer without detection will likely fuel calls for tighter internal monitoring.
The Department of Justice has faced broader scrutiny over how it handles cases involving threats to the president. Conservative critics have pointed to what they see as uneven enforcement, arguing that some cases are aggressively prosecuted while others are quietly dropped. The recent wave of criminal referrals from the Office of the Director of National Intelligence to the Justice Department reflects a broader push within the Trump administration to hold federal actors accountable through the legal system.
Authorities have not said whether DelleChiaie has retained counsel or entered a plea. The Secret Service, which led the investigation, has not released further details about the timeline between the alleged January searches and the April arrest.
DelleChiaie faces a federal court process that will determine whether the evidence supports the charge. Prosecutors will need to establish that the email constituted a true threat under the legal standard, not merely offensive or disturbing speech. The alleged months of research on a government computer could prove central to that argument.
Investigators will also need to determine whether DelleChiaie acted alone, whether anyone else at the FAA was aware of his alleged searches, and whether existing monitoring systems should have flagged his activity sooner. Those answers may take months to emerge.
For now, the case stands as one more entry in a growing list of federal prosecutions tied to threats against the president. Each one tests whether the system built to protect the commander in chief can keep pace with the people inside government who may wish him harm.
When a federal employee allegedly uses a government computer to research killing the president, then signs his own name to the threat, the question is not whether the system caught him. The question is what it missed while he was searching.
