Long ago her father had gone to China as a missionary, so Amie was in fact born in Shanghai. An unmarried woman, she had a special love for the Chinese. She treated the Chinese students as her own children and gave them meticulous care and attention. On each Thanksgiving and Christmas Eve she invited Chinese students to her family home. Pitifully, she was shot dead by a Chinese student.
