A U.S. Navy veteran in Utah was arrested Wednesday in connection with suspicious envelopes that were sent to President Donald Trump and top military chiefs.
William Clyde Allen III, 39, was taken into custody in in the small northern Utah city of Logan, said Melodie Rydalch, a spokeswoman for the state’s U.S. attorney’s office.
The arrest comes after authorities confirmed an investigation into two envelopes once thought to contain ricin and later found to be castor seeds, the substance from which the poison is derived. They can cause injury if swallowed.
The FBI said there were potentially hazardous chemicals involved with their operation in Utah on Wednesday, but declined to give additional details. No attorney was immediately listed for Allen.
The envelopes addressed to Defense Secretary Jim Mattis and the Navy’s top officer, Adm. John Richardson, were isolated at a mail screening facility and sent to the FBI. No one was injured, and neither envelope entered the Pentagon. Mattis is traveling in Europe this week. (Read more from “Navy Veteran Arrested in Connection With Trump Ricin Letter” HERE)
