An Ohio man who was to face trial this week for setting a fire that killed a girl he was accused of raping and her grandparents apparently committed suicide Monday when he jumped from a fourth-floor courthouse balcony.Robert Seman Jr., 48, was returning to the Mahoning County Jail from the county courthouse in Youngstown when he suddenly ran to the balcony and hurled himself over the edge. He was coming from a status conference before his trial was set to begin Tuesday in Portage County, 35 miles away."According to a couple of the attorneys and basically everybody there, it seemed like he was in pretty good spirits," Mahoning County Sheriff Jerry Greene told the Youngstown Vindicator. "He was talking about the future of his trial, and he just decided to jump."
