With respect to Darlene Heatherington and the other notorious case of public mischief from Lethbridge, she was charged on the basis of the false report she made to the police about being stalked and harassed rather than her secret escapades in Montana and the ruckus that resulted.
Heatherington was found guilty of public mischief on June 29, 2004:

She was sentenced to a 20-month conditional sentence order which included 8-months' house arrest in September 2004:

On appeal, the sentence was reduced to a 12-month conditional sentence:

Although we don't know all of the facts in the present case, a key distinction is that Heatherington reported to the police that she was being stalked and threatened. It later turned out that she authored the letters and emails herself fabricating the entire story.
