When the investigator showed Rizky and Vina's photo, there was an emotional change towards Pegi. However, it was not explained how the change occurred. The change in condition indicated that Pegi Setiawan knew about the murder incident. "In Pegi Setiawan's personality, there is a tendency to lie and manipulate because there is a difference in statements between Pegi Setiawan and his biological father," he said.

The conclusion from the forensic psychology examination results is that Pegi Setiawan has indications of committing a crime. "When asked about the incident above, he answered that he didn't know. However, if collateral examination is conducted, namely data, there are changes in emotional reactions," he said.

Then in the examination it was mentioned that initially Pegi did not know Sudirman's figure, one of the life sentence convicts in the murder case of Eky and Vina. However, in the second examination, Pegi recognized Sudirman as a friend from elementary school. In addition, Pegi had previously used illegal drugs in 2016 and was arrested at the Gunung Sari Cirebon Police Station.
