SAGINAW (WKZO) -- A suspicious letter was delivered to the office of U.S. Senator Carl Levin in Saginaw this morning prompting the evacuation of the office. One staff member was taken to the hospital as a precaution but has shown no signs of any problems.
A hazardous materials crew was called to the building on Washington Street around 11:30a.m.Wednesday and immediately cleared to the office.
It was just one incident of many triggered by the heightened state of alert around the Capitol triggered by an authentic attempt to send poison through the mail.
Three letters that have tested positive for the poison ricin have been traced to a man who has been taken into custody at his home in Corinth, Mississippi. Paul Kevin Curtis is being held pending a bond hearing.
The U.S. Postal Inspection service says those letters were sent to President Obama, Mississippi Senator Roger Wicker and a Mississippi Justice Official.
The FBI says there appears to be no connection to the events in Boston this week.According to Reuters, at least two of the letters included the same phrase: "To see a wrong and not expose it, is to become a silent partner to its continuance. I am KC and I approve this message,"
Federal investigators had questioned a person of interest in the area of the Senate Hart office building and had a backpack containing sealed envelopes, but released him.
There were also suspicious letters checked out in Ohio and Arizona and in the Senate offices of Joe Manchin and Richard Shelby. Most of them have turned out to be false alarms.
