CLEVELAND -- One year later, still many unanswered questions.
Monday marks a full year since Aliza Sherman was stabbed to death in downtown Cleveland.
A ceremony, organized by the "Justice for Aliza" group, will be held at 5 p.m. today at E. 12th and Hamilton -- near the location Sherman was killed.
To date, no arrests have been made and no suspects identified.
Despite authorities having evidence of a masked figure in black running from the crime scene, it's not enough to name a person of interest.
If you have any information about this case, call 216-252-7463. All tips can remain anonymous.
A $50,000 reward is being offered.
