ABSTRACT
Crime is an epidemic, and there is a need to spot crime doers. The research aimed to analyze systemic technical approaches to nipping crime in the bud. Police Primary School was employed. Recruitment was 100 pupils. They were five classes in all, and each classroom had 20 pupils. The pupils stayed in their classrooms. The research is in two phases: Phase 1 is voice recognition, and phase 2 is the truth serum approach. Phase 1 was to test the ability of students to recognize each other through a voice from spoken words between close associates. Each class was allocated twenty seconds for the ear witness voice recognition. The pupils in each class block utter sounds (speak), one after the other, and the other class block keenly listens to their voices for identification. In phase 2, pupils receive items as an enticement for the truth. This item is mind-altering, and the crime's identity is known. The research analyzed information obtained from the pupils after inducement to
ascertain the doer of the crime. In phase 1, pupils in the same classrooms' voice recognition scored above 70%, while pupils in different classrooms scored above 60% in all the classrooms demonstrated. Only Classrooms B and D were non-significant from other classrooms (P>0.05) in the same classrooms, while non-significant differences in the different classroom settings were observed. Pase-2 revealed above 60% of the crime doers. Only two classrooms were not significant. The most frequent crime is noise making. The divulging of information on crime doers was comparable in all.
