The man who was 17 years old when he shot and killed a UC student took a plea deal on Monday. Justin Dugan pleaded guilty to voluntary manslaughter and felonious assault, and in exchange the murder charge he faced was dropped. T he judge sentenced him to 21 years in prison. Although Dugan was 17 years old when he shot and killed 21-year-old Benjamin Addison in March 2024, a judge ruled that he would face trial as an adult. Addison was killed on Highland Avenue near Dorchester on March 30, 2024, after Cincinnati police said two teenagers tried to steal his car. On March 30, 2024, Benjamin Addison was found shot outside his vehicle on Highland Avenue, near Dorchester Avenue. His family said he'd decided to go out with some friends the night before."I called him at 10 p.m. because usually he comes home from school," his mother, Yeshi Leggesse told us after his murder. "He said to me, 'Mom we're celebrating, do you mind if I stay out?' And I thought, 'He's 21,' because he keeps telling me, 'I'm 21.'"She and Addison's father agreed it was fine if their son stayed out with his friends. They were out celebrating a friend's victory following a boxing event.Hear more from Addison's family below: University of Cincinnati remembers student shot, killed nearly one year ago"I said, 'Benjamin, if you need a ride home, call me.
