SANTA ANA, Calif.—A psychology professor has been ordered to stand trial in Southern California for the 1995 murder of a man she says raped her.

The Orange County Register (http://bit.ly/1coKAJJ) reports a judge found Wednesday that Norma Esparza should stand trial in the killing Gonzalo Ramirez, a man she says attacked her after she met him at a bar 18 years ago as a college student.

Esparza, a professor at an American university in Geneva who previously testified before a grand jury in the case, is one of four people who prosecutors allege plotted to kill Ramirez.

She turned down a plea bargain in November that would meant three years in state prison, saying prosecutors were trying to get her to falsely plead guilty.

She could get a life sentence if convicted.
