Narrow Down the Range

Luke seemed to be observing Sarah's body, but he was actually discreetly surveying everybody's reactions.

Regretfully, while their reactions weren't entirely the same, nothing suspicious really stood out.

Luke didn't find that odd.

The murderer attacked two people after Luke identified himself as a police officer. The suspect had to be a psycho, since no sane person would commit a crime when they knew police officers were present.

Luke and Selina began to ask everybody questions.

Both of them were using recorders that Luke had modified, and they didn't have to write everything down themselves.

Half an hour later, Elizabeth and Billy arrived. Elsa and her new partner Simmons, a young white detective, also showed up soon after that.

Their help would be indispensable since there were too many people that had to be questioned.
