Anna Marie Filser (July 7, 1906 in Bavaria, Germany – December 7, 1938 at the Ohio State Penitentiary) was a German-born American serial killer.

The youngest of 12 children, as a teenager, she had an affair with a Viennese physician. They had a son she named Oskar. Her scandalized family sent her and the baby to America in 1929. While staying with an aunt and uncle in Cincinnati, she met fellow German immigrant Philip Hahn, a telegraph operator; they married in 1930.

Hahn began poisoning and robbing elderly men and women in Cincinnati’s German community to support her gambling habit. Ernst Kohler, who died on May 6, 1933, was believed to be her first victim. Hahn had befriended him shortly before his death; he left her a house in his will.

Her next victim, Albert Palmer, 72, also died soon after she began caring for him. Prior to Parker’s death, she signed an I.O.U. for $1,000 that she borrowed from him, but after his death the document was either discarded or simply “disappeared.”

Jacob Wagner died on June 3, 1937 leaving $17,000 cash to his “beloved niece” Hahn. She soon began caring for 67-year-old George Gsellman, also of Cincinnati. For her service before his death July 6, 1937, she received $15,000.

Georg Obendoerfer was the last to die, on August 1, 1937, after he traveled to Colorado Springs, Colorado with Hahn and her son. Police said that Obendoerfer, a cobbler, “died in agony just after Mrs. Hahn had bent over his deathbed inquiring his name, professing she did not know the man.” Her son testified at her trial that he, his mother, and Obendoerfer traveled to Colorado by train from Cincinnati together and that Obendoerfer began getting sick en route.

An autopsy revealed high levels of arsenic in Obendoerfer’s body, which aroused police suspicions. Exhumations of two of her previous clients revealed that they had been poisoned.

Hahn was convicted after a sensational four-week trial in November 1937 and sentenced to death in Ohio’s electric chair, which was carried out on December 7, 1938. Hahn professed her innocence to the end, yet her 20-page written confession was discovered shortly after her death.
