Officer O'Neil

Officer O'Neil is an officer who responded to the hospital fire.

History
O'Neil was guarding the front entrance of the hospital when the fire caused an explosion. Arizona, Eliza, and Meredith ran to the door, but he stopped them because of the lockdown. Bailey opened the door and said she needed their help, telling him to let them in.

After the staff had been briefed on the fire, O'Neil told Bailey they were still looking for the rapist.

When Ben learned that he'd seen the rapist with Stephanie, he offered to show them where that happened. Firefighter Carroll said it was too dangerous, but O'Neil thought it was a good idea. While they debated, Ben took a coat and walked into the building. O'Neil and his crew followed.

Inside the building, they found the source of the explosion and found Keith's body on the floor. Ben knew it was too tall to be Stephanie and then he found a blood path that led them up to the roof, where Erin and Stephanie were.

Career
He works for the Seattle Metropolitan Police Department.
