Joana Holter, a 46‑year‑old White female, was found brutally slashed to death in her home on July 27, 1981. Investigative notes describe a sudden, savage attack with a large blade, indicating a targeted, personal assault. No arrest was made at the time and the case remained unsolved.

In the early 1980s serial killer Ottis Toole began confessing to many killings and, in written statements, placed himself at Holter’s scene, claiming he ambushed her while she tended groceries and used the same machete he later linked to the Adam Walsh case. Authorities have not tied his admissions to Holter’s murder with corroborating physical or witness evidence, and doubts have been raised about the reliability of many of his confessions.

The killing remains officially unsolved and no other suspects have been publicly named. Did anyone in the community have contact with Joana Holter or notice anything unusual around her home in late July 1981?
