The Joint Terrorism Task Force has now identified a Canadian woman as their prime suspect in the Trump assassination attempt, but have given no further details on who she is.
The tainted letter was stopped at the final off-site government mail center before it arrived at the White House.
The FBI said in a statement, according to Times:
“The FBI and our US Secret Service and US Postal Inspection Service partners are investigating a suspicious letter received at a US government mail facility,”
“At this time, there is no known threat to public safety.”
Similar envelopes were sent to law enforcement agencies in Texas, including a detention facility and a sheriff’s office.
No links have been found between the poisonous letter and any international terrorist organizations, investigators said. They declined to elaborate on what evidence they had that pointed them to the female suspect.
However, officials have said that the investigation is still in its early stages, and nothing has yet been ruled out.
Ricin Used In Assassination Attempts Before
Ricin is a powerful toxin produced in the seeds of the castor oil plant. The seed is so potent that a dose of purified ricin powder the size of a few grains of table salt can kill a human within three to five days.
A Navy veteran was arrested in connection with packages suspected to contain ricin that were mailed to Pentagon and Navy leadership in 2018. William Clyde Allen’s case is still pending because officials found he had sent castor beans instead of ricin powder.
Former President Barack Obama was also the target of a ricin attack. In 2013, actor Shannon Richardson was sentenced to 18 years in federal prison for mailing letter laced with ricin to Obama and Michael Bloomberg, then the mayor of New York.
