Lt. Christopher Paul Hasson, 49, was arrested Friday on gun and drug charges, but prosecutors said in the filing that the charges were just the “proverbial tip of the iceberg.”
The filing argued that Lieutenant Hasson should be held until he is tried, describing him as a “domestic terrorist” who intended “to murder innocent civilians on a scale rarely seen in this country.”
At a hearing on Thursday, Magistrate Judge Charles B. Day ordered that the lieutenant remain in federal custody for at least the next 14 days.
In their filing, prosecutors quoted a letter that he drafted to friends in 2017 and that the authorities found on his computer. In it, Lieutenant Hasson, who works as an acquisitions officer at Coast Guard headquarters in Washington, wrote: “I am dreaming of a way to kill almost every last person on the earth. I think a plague would be most successful but how do I acquire the needed / Spanish flu, botulism, anthrax not sure yet but will find something.”
