Facing a criminal suspect who might die at any moment, Officer Maori couldn't afford to neglect him, as the clues would end with the person's death.
Therefore, after the condition of the man with terminal stomach cancer had stabilized, Officer Maori interrogated him again. However, the man determined to die became only more steadfast in his idea of suicide, showing no willingness to speak.
In dealing with a bedridden criminal suspect who might die any time, Officer Maori couldn't use any extreme methods, and even had to ask questions in a soft and detailed manner, for fear that any emotional agitation might prove fatal for the suspect.
Under such circumstances, the investigation naturally made no progress.
The investigative deadlock made Officer Maori's already thinning hair increasingly trend towards baldness, but the work still had to be done, and overtime still had to be worked.
