A Wisconsin woman is facing two felony charges after an investigation found her responsible for emailing death threats and bomb scares to Republican senators during debate of the collective bargaining bill.

The criminal complaint alleged Katherine Windels of Cross Plains threatened to shoot Republican senators and, “because [that] just isn’t enough,” plant bombs near their houses, cars and the Capitol, according to the complaint. Sen. Robert Cowles, R-Green Bay, received the first email at 8:08 p.m. on March 9.

The email said a group of people had decided Cowles and other Republican senators had to die for their support of the budget repair bill, which would limit collective bargaining rights for most public employees. The email said the group planned to come to Cowles’ house and “place a nice little bullet in your head,” and had planted bombs in areas Cowles frequented.

According to the criminal complaint, Windels sent anther email later that day to Cowles and 14 other Republican senators containing similar threats to kill them and their families.

The emails were sent from a fraudulent account under the name “Lisa Patterson,” which investigators traced by secondary email and IP address to the home of Windels, the complaint said.

Windels admitted to sending the emails after being questioned by a Department of Justice special agent, but said she does not know why she sent them and never intended to follow through on any of the threats.

Windels faces two misdemeanor charges for computer threats to injure or harm and two felony counts for creating a bomb scare.

DOJ referred the criminal investigation to Dane County District Attorney Ismael Ozanne on March 18 for the charging decision, according to a statement by DOJ spokesperson Bill Cosh.

The criminal complaint was not filed until two weeks later, after Cosh released a statement of concern over the “lack of action” regarding the referral.

Ozanne said action was taken in a reasonable amount of time and he had nothing but respect for the DOJ Division of Criminal Investigation and their special agents.

He also confirmed Windels has not yet made an initial appearance in court.
