Social media and the internet have helped solve a Michigan-based disappearance dating back more than 30-years. 17-year old Carol Ann Cole of Kalamazoo vanished in 1980 shortly after leaving Michigan for Texas. For about as long, Louisiana authorities had been trying to identify the body of a young woman found in woods near Shreveport. Posts on Facebook and Craigslist, described as “happenstance”, helped bring together authorities and members of Cole’s family in February. It was six days after the Facebook page was launched.
