Deputy team leader and Xiao Hei returned to the detective bureau.
Luke asked, "Did you find any clues about the shooter?"
Xiao Hei poured a cup of coffee, sat at the table, and said, "The shooter was still at a long distance, and the shooting location was likely on the rooftop of a five-story building to the southeast. The shooting spot was cleaned up very well—no valuable clues were found, nor were any cartridge cases."
"How did you determine that the shooting location was on the rooftop?"
The deputy team leader answered, "We determined this by backtracking from Anise Snow's gunshot location and position. Additionally, we took statements from people in the building. By summarizing the contents of the statements, the highest probability is that the shooter was on the rooftop."
Luke continued to ask, "How did the shooter find Anise Snow?"
