The Last Known Movements of Dorothy Arnold
December 12, 1910 Timeline
On December 12, 1910, Dorothy Arnold left her family’s luxurious townhouse to walk along Fifth Avenue in Manhattan. She was accompanied by her mother for part of the route and then continued alone near her home. She was wearing a brown tailored suit, a muff, and carried a small package, blending in with other upper-class residents going about their daily routines.
Witnesses later reported seeing a young woman matching her description walking briskly and appearing composed. Around midday, she was observed entering a doorway at 145 East 36th Street, a building that housed both residential and commercial spaces.
