The murderer was unlucky to have encountered Brian.
Before, Brian had recorded the entire Los Angeles traffic electronic map at Parker Center to handle a large number of highway vehicle disappearances. Using his talent of Extensive Knowledge and Strong Memory, he etched the map into his brain.
So when he saw the patterns on three pieces of cloth, after simply combining them, he recognized their meaning.
This thing, it was part of the Los Angeles highway traffic routes.
The three strips of cloth had some overlap in routes.
If one understood the meaning of the blue lines and arranged them according to their original positions on the highways, overlapping them, the coordinate point where the lines connected would likely be the location of the murderer's next crime.
Looking at the place, it seemed to be located under an overpass.
Brian took out his phone and glanced at the time.
It was almost noon.
