A Gurnee man has been arrested and charged with murder after prosecutors say he fatally stabbed a 34-year-old man, whom he did not know, shortly after an attempted theft in North Chicago. An autopsy performed showed Gonzalez-Pena died as a result of a sharp force injury, Banek said. It showed Medina and another subject entering the liquor store to make a purchase. Medina returned to the liquor store wearing the same clothing about three hours later, just before the murder. The video showed Gonzalez-Pena, Gonzalez-Pena’s friend, Medina and a fourth subject, who has since been identified by investigators.
