(Chicago, IL)  —  An elderly man is under arrest in a cold case murder that took place nearly half-a-century ago in an area of Chicago, Illinois.  Police in Naperville say 76-year-old Barry Lee Whelpley was arrested in Mounds View on June 2nd for the 1972 murder of 15-year-old Julie Ann Hanson.  She was last seen riding her bike to her brother’s baseball game, and her body was later found in a field.  Police said she had been stabbed multiple times and was sexually assaulted.  At the time, Whelpley lived within a mile of the Hanson home, and police say recent breakthrough DNA technology led to his arrest.  Whelpley is awaiting extradition to Illinois.
