The man's mental condition and the smell on him clearly indicated that he had just taken drugs.
Luke had seen a lot of scumbags and dirty cops, but it was rare to see a scumbag like this one.
Big Nick and his men from the Los Angeles County Police could be considered good people compared with this guy.
At the very least, Big Nick and the others didn't take drugs, much less kill four- or five-year-olds.
Taking drugs on a case and killing people - it would be strange if this person wasn't a psycho.
Walking out the door, Luke's gaze paused for a moment on the door of apartment 6D on the right. He said something to the patrol officer before he went up the stairs to the rooftop.
A moment later, he came down and drove off.
When he returned to Shake Shack, he saw the two girls standing there with two big paper bags each.
Looking at the time, Luke slapped his forehead.
