Warning: Sad story. This is an entry my husband just showed me from his father's journal. In 1970 my father-in-law was stationed in San Jose, Costa Rica. His wife, Arlene, was teaching senior high school English classes at an American school that served ex pats' kids, diplomat families, etc.
10/27/70 – Arlene calls the wife of the Chinese Ambassador to tell her that their children have to turn in some homework. She expresses surprise and said the children studied at home a great deal. 30 minutes later she grabs a gun from a guard and kills herself.
I can't find a reference to this online.
