 The law was named for Marie Varsos and her mother. They were murdered by Marie's abusive husband after he was arrested and then almost immediately released for strangling her until she lost consciousness. After being released, he tracked her down and waited outside for 45 minutes in a rental car stocked with zip ties and weapons before murdering Marie and his mother-in-law. Marie's brother, Alex Yon, has been advocating for this new GPS measure for more than two years.
