CONCORD, N.H. — A Federal Aviation Administration employee in New Hampshire is accused of sending an email to the White House threatening to kill President Donald Trump after using his work computer to research assassination attempts and related topics.

Dean DelleChiaie, 35, of Nashua, was expected to make an initial court appearance Tuesday on a charge of interstate communication of a threat against the president. According to federal prosecutors, he sent a message April 21 using his personal email account in which he identified himself and said he was going to “neutralize/kill” the president.

That came nearly three months after police and U.S. Secret Service officers questioned DelleChiaie about searches made on his computer at the FAA, where he was employed as a contractor involved in mechanical engineering.

According to court documents, DelleChiaie used his work computer in January to search for information about how to get a gun into a federal facility, the percentage of the population that wants the president dead, the location of the vice president’s home and the names of his children. He later asked the FAA’s information technology department to delete his search history, but the department instead reported the request to authorities, and DelleChiaie was suspended.

When interviewed at his home Feb. 3, DelleChiaie admitted to making the searches and was remorseful, Secret Service Special Agent Nathaneal Gamble wrote. He also told investigators he owned three guns, was depressed and that while he was upset with the Trump administration, he had no interest in assassinations.

DelleChiaie, whose attorney did not immediately respond to a phone message seeking comment, was arrested Monday, just over a week after a gunman tried to storm the White House Correspondents’ Association dinner with guns and knives. Cole Tomas Allen has been charged in that incident, in which a Secret Service officer who was wearing body armor was shot but not seriously injured.
