Criminal procedural law is the entire legal rule regarding how to implement criminal
law provisions, if there is a violation of the norms referred to by this provision. So that the
criminal procedural law was created as a means in the framework of law enforcement and
justice in realizing an orderly and peaceful life in society. The encapsulation of Indonesia as
a law and order nation is to make legal guidelines in which one of these regulations is the
Criminal Technique Code which is a rule for looking for and getting material truth, in
particular the total reality of a crook case by applying legitimate arrangements genuinely and
unequivocally, to figure out who the culprits are who can be accused of an infringement of
the law and afterward request an assessment and court choice to decide if it is demonstrated
that a wrongdoing has been perpetrated and whether the denounced individual can be
accused.
In the Criminal Procedure Code (KUHAP), namely Law Number 8 of 1981, Article 1
points 1 and 2 define the meaning of investigation. Investigation of criminal acts is essentially
a law enforcement effort that is limited and restrains the rights of citizens, aims to restore
the disruption of the balance between individual interests and public interests so that a
situation of security and order is maintained and created because a criminal investigation is
also part of criminal law enforcement, it must be carried out based on the provisions and
regulations in force (Ali, 2022) .
Regulation infringement that have been overflowing in Indonesia of late are murders.
The meaning of homicide is a crook act that causes the passing of an individual's life,
presently, many killings happen in different locales of Indonesia. Aside from being impacted

The homicide was propelled by three intentions, in particular property or economy,
power, and social relations. One of these thought processes could be the justification for the

The expansion in criminal demonstrations requires the job and obligations of the
specialists including the Police, particularly the Criminal Examination Unit, in revealing the
reasons for murders carried out by culprits requiring difficult work from the Police. Aside
from the Police, another authority is the Principal legal officer's Office. Participation between
the Police and the Examiner's Office in settling cases assumes a significant part in criminal
policing.
A crook act is a demonstration that is denied by a law and order, which restriction is
joined by dangers (sanctions) as specific punishments, for any individual who disregards the
preclusion (Chazawi, 2002). The effect of a wrongdoing/infringement is criminal obligation,
while the meaning of criminal obligation is criminally liable for somebody who carries out a
lawbreaker act or criminal demonstration (Saleh, 1981). One of the crimes in murder cases
is premeditated murder. Homicide is an act of killing someone by violating the law.
