The prosecutors in the Denny Ross case are expected to have their closing arguments next week.

He told jurors he was friends with Ross, and the two smoked pot, drank beer, and played video games many times at Ross' apartment in Springfield Township.
Riley testified he and Ross got into two fights. In the second fight, Riley said he broke Ross's arm. During the first trial in 1999, he appeared in court with his left arm in a cast.

Hill was found strangled and stuffed in the trunk of her gold Geo Prism in Ellet approximately a week after she was reported missing.
