(Cleveland) - Aliza Sherman's family just raised the reward for the arrest of her killer to $50,000.

The 53-year-old from Beachwood was found lying in a pool of blood on a Sunday evening in March near the Galleria at Erieview Mall.

Sherman was stabbed 11 times. The mother of four was reportedly visiting her lawyer downtown in regards to her divorce proceedings.

Even though she was in a high traffic area with lots of coverage by security cameras, no suspects have been identified. Police did release video of a shadowy image running from the crime scene. Some people believe it was a profession hit.

Tips should be directed to the Cleveland Police Homicide Unit at 216-623-5464.
