CLEVELAND, Ohio – An FBI spokeswoman says federal agents on Tuesday assisted in the execution of a search warrant at the law firm Stafford & Stafford where Beachwood mother Aliza Sherman retained a divorce attorney until her murder last year outside the firm's downtown offices.

Officials would not say whether the hours-long search was related to Sherman's brutal daylight murder in March 2013 or the December indictment of her former attorney, Gregory J. Moore, who is accused of calling in bomb threats to the old county courthouse on Lakeside Avenue.

The Cuyahoga County Prosecutor’s office requested the search, which included sheriff’s deputies and agents from the Ohio Bureau of Criminal Investigation, a spokesman said.

Stafford & Stafford does not list Moore as one of its associates. A call requesting information about Moore’s status at the firm was not returned.

Sherman, 53, was found stabbed 11 times at Erieview Plaza. She was there to meet with Moore about an upcoming court proceeding, officials said.

No suspect has been identified.
