Prosecutors hope to hold only one trial.
But if that's not possible, Chief Deputy District Attorney Mary Keenan said, she'll make the unprecedented move to conduct simultaneous jury trials in separate courtrooms. The five suspects are charged with raping the woman for more than two hours before setting her free in Lefthand Canyon.
