Luis Quinones, 27, of Butler, who is accused of sexually harassing and assaulting Butler County Prison inmates, is headed to trial.

Butler District Judge William Fullerton today ruled there was sufficient evidence the case should move to county court.

Quinones, who works for Trinity Services Group of Chicago, is charged with institutional sexual assault, attempted sexual assault and indecent assault.

He is accused of sexually assaulting and harassing one inmate as well as sexually harassing a second inmate.

Attorney Armand Cingolani argued there was insufficient evidence to move forward, but Fullerton disagreed.

The prosecution only called county Chief Detective Chuck Barger, who testified about his interviews with the two inmates and Quinones about the allegations.

Cingolani was not permitted to call witnesses. Fullerton said that could be done at trial.
