Ann Marie Burr (December 14, 1952 — disappeared August 31, 1961) was an American child who vanished under mysterious circumstances from her home in the North End section of Tacoma, Washington. Her disappearance, which made national headlines, received renewed attention when it was theorized that serial killer Ted Bundy – who lived in Tacoma as a teenager at the time – might have been responsible for her abduction.
The first of four children of a middle-class Catholic family, Burr was raised in Tacoma alongside her three siblings. On the night of August 30, 1961, Ann went to sleep in an upstairs bedroom of the family's home, which she shared with her three-year-old sister. At some point during the evening, Burr awoke her mother, Beverly, notifying her that her younger sister, recovering from a broken arm, was crying. After comforting the three-year-old, Beverly put both girls back to bed. At approximately 5:30 a.m. on August 31, the family realized that Burr was no longer in her bedroom. Searches of the home revealed the front door had been left ajar, a living-room window open, and the girl nowhere to be found.
Burr’s disappearance sparked a significant manhunt, utilizing soldiers from nearby Fort Lewis, as well as members of the National Guard. Though several individuals were considered potential suspects in the years immediately following the disappearance, none led to Burr’s recovery.
After Bundy was apprehended in 1978, he was considered a suspect when it was revealed that he (aged 14 in 1961) had lived near the Burr residence, that he delivered newspapers near Burr's house, and that the Burr home was very close to one of Bundy's earlier childhood homes where his favorite great-uncle lived. A size-6 shoe imprint was found outside the open living-room window, and some investigators believed this was consistent with a teenaged perpetrator. After corresponding with Bundy prior to his 1989 execution, Burr’s parents publicly stated that, based on circumstantial evidence, they believed their daughter's remains may have been buried on the University of Puget Sound campus.
In 2011, forensic testing of material evidence from the Burr crime scene yielded insufficient intact DNA sequences for comparison with Bundy's. As of 2023, Burr's whereabouts remain unknown.
