Anna Lisa Goulder was 37 when she was last seen at a Market Basket in Burlington, Massachusetts, on March 24, 2020. She was not reported missing to the Billerica Police Department until July 7, 2020, a gap the family says complicated the early inquiry. Authorities and family expressed particular concern because she had a history of mental illness, which they felt made her vulnerable.

Investigators developed a lead suggesting Anna Lisa may have traveled to Los Angeles, arriving there on April 4, 2020. Family members said she had gone missing and later turned up in Los Angeles about five years earlier, which gave them hope this might be a repeat pattern. She was known to frequent libraries, and police asked anyone with information to come forward.

Does anyone who saw Anna Lisa in Massachusetts or Los Angeles in spring 2020, or who remembers her visiting local libraries, have information that could help locate her?
