Alan Hruby was a 19-year-old freshman at the University of Oklahoma studying political science. His parents, John and Joy Hruby, ran ‘The Marlow Review,’ a weekly newspaper, and were well known in their community. Alan’s 17-year-old sister Katherine also worked for the Marlow review, and when the Hruby’s didn’t show up for work on October 10, 2014, no one expected to discover that they had all been murdered by a member of their own family.
