But why?

Mary Kay Bower, 42, of St. Paul, Minnesota, was arrested on Oct. 19 for rustling and livestock theft, which is a felony, the Minneapolis Star-Tribune reported. Officers were alerted when Bower was seen walking a sheep and a dog on leashes. Bower told them that she purchased the sheep for $200, but her companion said she stepped over a farm fence, put a leash on the sheep and pulled it out through the fence. When police checked, they found out that Bower had not paid for the animal, a breeding hair ram worth about $500.
