Mary Ann Waite was 25 when she was last seen in Brockton, Massachusetts, on June 1, 1971. She was described as five feet six inches tall with black hair and brown eyes.

Official records name Brockton, in Plymouth County, as her last known location, yet the Baltimore County Police Department in Maryland is recorded as the primary agency handling the case; the reasons for that jurisdictional link are not publicly explained.

Online discussions and genealogical threads have circulated unverified stories that Waite may have left and returned to her family previously, and even claims she later lived in Florida under another name and died in 2006. If anyone knew Mary Ann, her family, or has verifiable information about her whereabouts after June 1, 1971, please share what can help the investigation.
