According to Cassandra Maynard, Dehna was a Senior Year Exchange student who lived with Jack (John) Wolfe for 1964/65 school year.  He was popular with the students.  Everyone seemed to like him a lot.  Jack was a friend of Cassandra so she saw Wolfgang quite a lot.  When Cassandra went to the Napa Fair Grounds 1960's group reunion, she saw that Wolfgang was listed on the "deceased board."
