Aaren O'Connor, 25, moved from California to Chicago just over a year ago for a new job and to be with her boyfriend.
"I pleaded with her when she told me she was going to go to Chicago. I said there are much safer places for you to be," Aaren's father, David O'Connor, told ABC owned station WLS.
Aaren was hit by a stray bullet as she was sitting in her car after work, police confirmed to ABC News. According to David O'Connor, Aaren was on the phone with her sister when the shooting happened. He tried calling his daughter back when the line cut out.
"She was incoherent, didn't know where she was, and kept saying that her head hurts. Her head hurts," he told WLS. "I wish I could have known what was going on, so I could have told her that I love her one more time."
A spokesperson for John H. Stroger Hospital of Cook County confirmed O'Connor's death to ABC News on Tuesday.
According to a Chicago police spokesperson, there have been 70 murders in the city so far this year. By contrast, there had only been 35 murders during that same time period in 2015, meaning the number of homicides has doubled so far this year.
