Jakarta. The Witness and Victim Protection Agency, or LPSK, said it will offer psychological assistance to five survivors from Tuesday's (27/12) tragic murder case in a house in Pulomas, East Jakarta.

Six people were killed on Tuesday after two intruders locked up 11 people in a 2.25-square meter bathroom with no adequate ventilation for more than 12 hours.

The other five survived and are currently in intensive care at a nearby hospital.

"We hope the case can be solved soon since we have five survivors," LPSK vice chairman Askari Razak said on Wednesday.

The murderers killed their main target, 59-year-old Dodi Triono, along with his two daughters, 16-year-old Diona Andra Putri and 9-year-old Denianita Gemma Dzalfayla, and Dodi's drivers, Yanto and Tasrok.

The five survivors are Dodi's 13-year old daughter Zanette Kalila and four domestic workers: 41-year old Emi, 22-year old Nursanti, 23-year old Fitriani and 23-year old Windy.

The injured victims are still in intensive care at Kartika Hospital in Pulomas, not far from the house where they were locked up for almost a day.

Police say they are still investigating the motive behind the tragic murder.

Reports now claim that robbery is out of the question, as the intruders had not taken anything of value from Dodi's luxury house.

Indonesian Commission for Child Protection (KPAI) commissioner Erlinda Iswanto said she believed the real motive could have been revenge.
