A Sun Prairie woman was convicted Friday of homicide by negligent driving after a jury found she was writing a text message when she slammed into a UW-Madison student as he stood behind his broken-down car on East Johnson Street in 2010. The jury of seven women and five men apparently rejected Stephanie Kanoff?s contention that she was driving behind a car that had blocked her view of Dylan Ellefson?s car and the brightly-clad Ellefson, 21, who was wearing a Halloween costume to work at Hot Topic in the East Towne Mall.
