Jakarta. The Jakarta Police on Friday searched the home of a witness in the chilling rape and murder of a 9-year-old girl, after tests results showed that DNA samples taken from her body matched those of the witness.

Investigators are waiting for the outcome of DNA tests conducted at a different lab to confirm their findings before naming the witness, who is currently only identified as A.

Police decided to conduct a search of A's home despite the lack of confirmation after A. was named a suspect in the sexual assault of another young girl, identified as T.

The horrific murder of Putri Nur Fauziyah shocked Jakarta last week when the 9-year-old school girl's lifeless body was found stuffed in a cardboard box in Kalideres, West Jakarta.

Both Putri and T. live in the same neighborhood as A.

Investigators have interviewed 13 witnesses in Putri's case so far and nearly each spoke of A.'s "sexual perversions" and drug use.

“T. said she visited A.'s house three times in June. One day she found herself locked in the house, from around 9 p.m. to 6 a.m., during which she was [allegedly] sexually assaulted by A.," said Jakarta Police general crimes director Sr. Comr. Krishna Murti.

"Other witnesses told us that A. frequently asked them to take drugs with him."

He added that A. had tested positive for methamphetamine according to a urine test conducted on Tuesday.
