The threats came primarily by email but also by letter, phone, verbally and via Twitter, Facebook and Craigslist from people living in Wisconsin and as far away as Maine, Florida, Nebraska and California. One tweet said the writer wanted an anvil to fall on the governor’s head.

The suspects ranged from a man described as “dangerous” who was arrested by federal agents in March for threatening several public officials in Maine to hapless drunks who said they were angry but had no plans to hurt anyone. A surprising number of the threats were signed, although some used fake names.

The documents don’t reveal the intended targets or the suspects in any of the 11 ongoing investigations except for Katherine Windels of Cross Plains, who was charged March 31 in Dane County Circuit Court with sending emails threatening 15 Republican senators and their families. She faces two felony bomb scare counts and two misdemeanor counts of sending a computer message threatening injury or harm. The 26-year-old day care worker told investigators she had no plans to carry out her threats.
