Officials reported that Winters allegedly threw a knife at an officer, although it did not make contact. Attempting to flee, she was tased and subsequently subdued.

As officers attempted to take her into custody, she pulled a second large knife from her waistband, according to court documents. An officer disarmed Winters and arrested her.
