Police are turning to Facebook and bank records to try to identify a motive for why four people were killed at a North Dakota business two months ago. Court documents show police have sought search warrants for Isaak's personal and business bank records, as well as victims' Facebook accounts. Flaten said the connection between the business and Isaak's home would need more reasoning to be considered a motive. They also searched Isaak's home and business in Washburn, according to affidavits and search warrant receipts. ___Information from: Bismarck Tribune, http://www.bismarcktribune.com
