The charges stem from a four-day crime spree involving Dean and Joshua Wade, then 16, whom prosecutors described as Dean’s “sidekick.”
The “crime team,” prosecutors said, murdered Arnold and days earlier committed an armed robbery and terrorized Dibert Avenue residents in a drive-by shooting.
Wade, who fired the shot that killed Arnold and was identified as the gunman in the drive-by shooting, was sentenced to life in prison in 2006 for his role in the crimes.
That same year, Dean was convicted and sentenced to death.
The Ohio Supreme Court overturned his conviction in 2010, determining Clark County Judge Douglas Rastatter made rulings and statements during the trial that “demonstrated bias against Dean and his attorneys that prevented Dean from receiving a fair trial.”
Prosecutors and Dean’s attorney declined to comment about the verdict. Arnold’s family members also declined to comment.
But Arnold’s mother, Vickie, said in 2010 that Rastatter was more than fair in the first trial.
“I think he got a fair trial the first time,” Arnold said then. “It isn’t fair to our family to put us through that again.”
