The Cuyahoga County Prosecutor's Office said Moore was not prepared for the divorce trial, which was scheduled to begin the day after the homicide. Investigators also said he made false statements to detectives about his whereabouts that day.
A month after Sherman was stabbed to death, the Cleveland Division of Police released surveillance video of a person of interest. The suspect is dressed in black and was seen fleeing near East 13th Street.
No one has been charged with Sherman's murder.
