Elizabeth Diaz was 29 when she disappeared from Springfield, Massachusetts, after leaving her home on September 7, 1999. She left behind medication she needed following a bone marrow transplant for leukemia. At the time she was recovering from addiction and a high-risk lifestyle but had been making progress — passing exams to enter nursing school and the police department.

Her younger child had recently gone to live with his father because her health made caregiving difficult. Authorities have suggested she might have traveled to Boston or Roxbury, but no concrete evidence has surfaced and she is classified as endangered missing.

Did anyone in Springfield, Boston, or Roxbury see Elizabeth around that time or know where she went?
