A woman arrested by U.S. officials on suspicion of sending an envelope full of ricin-filled to the White House and five other addresses in Texas will appear in federal court in Buffalo, New York, on Tuesday.
On Sunday, on the Canadian-American border at the Peace Bridge between Fort Erie, Ontario and Buffalo, U.S. authorities arrested a woman.
Her first appearance before District Judge H. Kenneth Schroeder Jr. is scheduled for 4:00 p.m. (2000 GMT). She was not formally acknowledged yet.
Before arriving in the White House, Canadian Police said Saturday, they intercepted the envelope in a government mail center.
On Monday, Canadian police searched an apartment in a suburb of Montreal related to the woman. According to two sources, she has dual Canadian and French citizenship.
The woman is suspected of sending a total of six letters, the other five of which are addressed to police and detention centers in South Texas, according to an American source.
To date, no links to political or terrorist groups have been found, but the investigation is ongoing, the source said.
The Mission, Texas, police department received a suspicious letter last week, Art Flores, a department spokesman, said Monday. The department did not open the envelope and turned it over to the FBI, he said.
Flores also said Mission police had arrested the woman, who is now scheduled to be held in Buffalo in early 2019.
Castor beans are naturally found in castor beans, but it takes a conscious act to turn it into a biological weapon. Castor beans can cause death within 36 to 72 hours by an amount as small as the head of a pin. There is no known antidote.
