WARREN — A city man has been sentenced to 15 to 20 years in prison after being convicted on charges of aggravated robbery, felonious assault and trespass in a habitation.

The charges against Craig S. Ison Jr., 42, of Orchard Court NE, stem from two incidents.

During a hearing Tuesday before Trumbull County Common Pleas Court Judge Ronald J. Rice, Ison said only two words, “I’m sorry.”

According to prosecutors and a police report, Ison assaulted and robbed a 72-year-old woman July 11 in the 100 block of Main Avenue SW in downtown Warren. The victim, an employee of a law firm inside the Huntington Bank Building, was attacked just before 11 a.m. as she entered the building.

Prosecutors said Ison pushed the woman through a glass display case, cutting her head, and repeatedly punched her while she was on the ground. The woman gave him cash to stop the assault. When police arrested Ison, they recovered $24 stained with what appeared to be blood, according to police. The victim at trial identified Ison as her attacker, and also detailed the injuries she sustained to her head and back.

The trespass charge relates to an incident April 7 at a Tod Avenue SW home. During that incident, prosecutors said Ison was discovered in the living room with one hand down his pants and the other on a 4-year-old girl. The child’s mother and grandmother forced him from the home, according to the prosecutors and a police report.

Both incidents were tried together, resulting in Ison’s conviction on all charges.

Assistant Prosecutor Michael Burnett said the case, which took 60 days from indictment to sentencing, should set the standard for the swift handling of crimes.

“We must aggressively prosecute people like this who commit extreme acts of violence. Not only to punish these offenders but to send a message to others that those who victimize the citizens of Trumbull County will face swift and stern justice,” he said.
