Brett's team has begun cataloguing information on every person who was in the room at the time of the murder. One person takes down names while another runs a rapid background check on each person, and one more is accessing the room's security cameras to ascertain each person's position when Katariki was shot. You note that another of Brett's team is searching everyone present. No weapon of any kind is found.
Two field agents take up a position on either side of Katariki's body, to prevent any tampering with the corpse. A heavy sheet is found, and laid over the body.
Brett himself speaks with the field agent who found the bullet. Once again, you note that it lodged at a low level, not high above your knees. Even given that Katariki's head might have diverted its trajectory, you realize he was probably killed by a high-angle shot. You glance out the window, mentally tracing the bullet's probable path back to its origin. And there your eyes alight on the flat roof of the four-story department store across the street.
Could that be where the killer fired from? If that's the case, it's strange that the bullet didn't break the plate-glass window in between the two points.
