Chicago Man Pleads Guilty To 2012 Attack
Of Cook County Prosecutor

One of two Chicago men charged with beating and stabbing a Cook County Assistant State’s Attorney who attempted to come to the aid of a couple being harassed along the Chicago lakefront was sentenced to four years in prison today, according to the Office of Cook County State’s Attorney Anita Alvarez.

Luis Cotto, 24, pled guilty to one count of Aggravated Battery (Great Bodily Harm) for his role in the 2012 attack that severely injured the off-duty prosecutor who was attempting to come to the aid of a same-sex couple as they were being verbally attacked and assaulted by the two defendants near Diversey Harbor. 

According to prosecutors, during the early evening hours on Sept. 13, 2012, the victim was going fishing at the lakefront when he observed two men in the area holding hands as they walked along the harbor.  As the couple walked by the victim, Cotto and co-defendant Edgar Diaz approached the couple, punched one of the men and verbally harassed them.  The victim yelled at the defendants to stop and Cotto and Diaz then targeted the victim and moved towards him.  

As the victim turned to run, he fell and both defendants began punching and kicking the victim with their hands and feet.  During the altercation, Cotto broke a bottle over the victim’s back and used it to stab the victim.  Both defendants continued to beat the victim.  Eventually, Cotto and Diaz ended the assault and left the area.

According to prosecutors, the victim was treated at a local hospital for numerous injuries, including a laceration to his head, a puncture wound to his left arm and a deep cut under his right arm which required over 40 stitches to close. The victim, who joined the State’s Attorney in 1998, recovered from his injuries and has since resigned from the office.

Cook County Judge William O’Brien sentenced Cotto to the four-year prison term today during a hearing at the Cook County Criminal Courthouse in Skokie.  Diaz, 22, is awaiting trial.

State’s Attorney Alvarez thanked Assistant State’s Attorneys Brian Sexton and James McKay as well as the Chicago Police Department for their work on this case.
