Computer software written by St. Louis County, Minn., Sheriff’s Rescue Squad Lt. Rick Slatten was instrumental in helping searchers find an autistic man who was missing for seven days in Burnett County, Minn. Slatten’s program, called “Search Tracker,” used the laws of probability to guide searchers who found Keith Kennedy late Sunday in a wooded area inaccessible by vehicles. He was about a mile from the Trade Lake Camp in Grantsburg, Minn., from which he vanished June 15.
