''A U.S. judge has entered a plea of not guilty on behalf of the woman suspected of sending ricin-laced envelopes from Canada to the White House and to several officials in Texas.
Pascale Ferrier, 53, made a brief appearance in a Buffalo, N.Y., courtroom this afternoon after she
was arrested over the weekend at the Peace Bridge border crossing between Fort Erie, Ont., and New York State. She faces a charge of threatening the president.
U.S. Magistrate Judge H. Kenneth Schroeder Jr. said since it is a criminal complaint there was no need for her to enter a plea during her brief court appearance today, but he entered a plea of not guilty on her behalf.
The matter was put over until Monday for an identity and probable cause hearing.''
The sheriff's office said Ferrier was booked into the Hidalgo County Jail by the Mission Police Department.
"The author clearly stated a desire to harm Sheriff Guerra and three female detention officers as they too were sent letters. The letters were intercepted at the Hidalgo County Detention Center, without incident," says the statement sent today.
"The FBI was able to confirm the substance found in all four letters received was ricin, a potentially deadly poison."
