Speak to Heidi in The Park, find her twin Hannah in the apartment, then return to Heidi to finish Carbon Copy and receive Untapped Mother’s Locket.
You’ll find Heidi’s shelter near East Supply Route Station. During your initial conversation, she tells you her identical twin sister Hannah is missing. That’s who you’re looking for. Her request takes you across the rooftops to an apartment building, then back to her shelter.
