According to Surawan, the police's belief is based on several documents related to the identity of Pegi alis Perong obtained by investigators from both the family and other sources. The documents obtained by investigators include Family Card, Junior High School Diploma, one sheet of Smart Indonesia Card, and two sheets of examination cards under the name of Pegi Setiawan.

The investigator also believes that the man captured is known as Pegi or Perong from the license plate number of the pink motorcycle obtained from the victim's parents' house.

While the Head of Public Relations Division of West Java Regional Police, Commissioner Pol Julus Abraham Abast, added that the investigators during the investigation process obtained statements from more than two witnesses who stated that the suspect PS was at the location at the time of the incident.

"So we are not making things up based on assumptions. Of course, investigator friends work based on existing procedures, evidence, and the evidence obtained," said Abast.
