Aliza Sherman was 53 when she was murdered on March 24, 2013, in downtown Cleveland. She was a fertility nurse at the Cleveland Clinic and was walking to meet her divorce attorney at 75 Erieview Plaza when she was stabbed 11 times—once in the right arm, twice in the neck, and eight times in the back—about 30 feet from the attorney’s office entrance. A bystander called 911 after hearing her cries, but she was pronounced dead at MetroHealth Medical Center shortly afterward.

Security cameras captured only a hooded figure fleeing; the footage was too poor and the assailant too disguised to be identified. The motive was not robbery, since jewelry and other belongings were not taken and the murder weapon was never recovered. At the time Aliza was engaged in a contentious divorce from Sanford Sherman, and her scheduled attorney, Gregory Moore, later faced indictment for falsifying his whereabouts at the time of the murder and for separate bomb threat charges. No one has been charged in Aliza’s killing. The Ohio Bureau of Criminal Investigation has since taken over the case and a $100,000 reward is being offered for information leading to an arrest.

If anyone knew Aliza, her routines, or saw anything near 75 Erieview Plaza on March 24, 2013, please come forward with tips.
