Naked Knife Girl Knew Her Killer, Says Crime Expert

DENPASAR

Dewa Agung Ayu Diah Cahyani, the 18-year-old health sciences student found naked and stabbed to death in her Denpasar boarding house bed three weeks ago, most likely knew her killer, says Udayana University criminologist Gede Made Swardana.

And he discounts the psychopath theory that is one line of police inquiry in the investigation, saying the theft of Cahayani’s motorbike, laptop computer, mobile phone and other possessions indicated she was killed resisting an armed robber.

Cahyani, known to friends and family as Echa and the daughter of a top Bangli bureaucrat, was found with multiple stab wounds and a knife thrust fatally through the back of her neck around 5pm on September 7 when her uncle called at her Panjer boarding house.

Her father had asked him to check on her because her mobile phone had been unreachable all that day.

Last week police said they had interviewed 30 people, including all the occupants of the student boarding house where Cahyani lived, seeking all possible information on the circumstances of the killing. None of the boarding house occupants was a suspect.

Cahyani’s motorbike was found later at Mengwi in Badung with fingerprints police believe are those of her killer.

Because Cahyani was found naked police were also investigating whether there was a sexual motive. But her family refused to allow an autopsy which could have established whether she had sex in the hours leading up to her death.

Swardana said this week he believed Cahyani’s killer did not fit the psychopath profile because he had benefited from the crime – her possessions had been stolen — and it was committed at the height of Idul Fitri and in torrential rain, which would have reduced the chance of the criminal being discovered.

He said it appeared the killer knew the exact location of Cahyani’s bedroom. The killer may have gone there intending to rape Cahyani and have become violent when she resisted.

Bur police said this week it looked as if the crime had been planned and that murder rather than rape or robbery was the aim. A source said the killer may have held a grudge against her, judging from the multiple knife wounds and the fact that the knife was left impaled in her neck.
