City officials announced an increased reward regarding the murder of Aliza Sherman.
The award is now $100,000 for information leading to an arrest and conviction in the case. The previous reward was $50,000.
Sherman, 53, a Cleveland Clinic nurse, was stabbed to death March 24, 2013 outside the 55 Erieview Plaza building.
No arrests have been made in the case, though police have surveillance footage from that day showing a potential suspect dressed in dark clothing and a mask.
Sherman's divorce attorney, Gregory Moore, recently pleaded guilty to charges of falsification and inducing panic for calling in bomb threats to local courts.
He admitted to lying to Sherman and investigators who were looking into her murder.
