COLUMBUS, Ohio — The U.S. Supreme Court has let stand a man’s conviction and death sentence for the Ohio killing of a youth counselor.

The Springfield News-Sun ( ) reports the court rejected an appeal Monday from 41-year-old Jason Dean, who was convicted in 2006 of killing Titus Arnold during a four-day shooting spree in Springfield.

The Ohio Supreme Court ruled 6-1 last year that Dean showed little remorse and the circumstances of the slaying during a robbery outweighed any evidence Dean presented in his favor.

The state Supreme Court had previously ordered a new trial for Dean even as the justices acknowledged substantial evidence of his guilt. That unanimous ruling said a Clark County judge was so biased against Dean’s attorneys that it tainted his trial. Dean was re-tried and sentenced to death.
