SPOKANE, Wash. (AP) — Spokane police said Friday they’re no longer investigating racial harassment claims made by Rachel Dolezal, the head of a local NAACP chapter whose integrity was thrown into question when her mother said she’s a white woman pretending to be black. Dolezal has filed police complaints, saying she received hate mail at the organization’s post office box. Post office workers, however, have said it’s unlikely a letter that didn’t have a date stamp or bar code could have been placed in the box without a key. Inquiries into the complaints were suspended this week, Spokane police spokeswoman Teresa Fuller said. They could reopen if new information emerges, she said.
