JAKARTA (JAKARTA POST/ASIA NEWS NETWORK) - Eight foreign drug convicts, including ringleaders of the so-called "Bali Nine" heroin-trafficking gang Myuran Sukumaran and Andrew Chan, are expected to be executed via firing squad soon, after the authorities gave them formal notice of their executions.

Under Law No. 2/1964 on execution procedures, a prosecutor is tasked with leading an execution.

The Attorney-General's Office has allocated around 200 million rupiah (S$20,000) for the cost of executing each person.

Here is how Indonesia carries out executions, according to the law:

1. Death-row convicts are to be moved to a prison or an isolation cell of a prosecutor's choosing, where he or she will be informed of their execution three days beforehand. At this time, the prosecutor should accept any messages or thoughts the convict would like to convey.

2. The execution must not be made public and should be done as simple as possible unless the president orders otherwise. The convict's lawyer can attend the execution upon request.

3. The provincial police will form a firing squad made up of 12 enlisted officers and one non-commissioned officer, who will be led by a high-ranking officer. The prosecutor will have full authority over the firing squad until the executions are complete.

4. The convict, dressed simply, will be escorted by the police to the designated location of the execution. The convict may also request religious counsel to accompany him or her.

5. Once at the destination, an officer will blindfold the convict unless he or she requests otherwise. The convict may choose to stand, sit or kneel. The convict may also have their hands and feet tied if the prosecutor deems it necessary.

6. Once the convict is deemed ready, the firing squad will be called to assemble with their firearms, where they will position themselves no less than 5m and no more than 10m from the convict.

7. The prosecutor will then order the execution to start, to which the firing squad's commander will lift his sword to signal the squad to focus their firearms on the convict's heart, then lower the sword to order the shooting to start.

8. If the convict still shows signs of life, the police commander will order the non-commissioned officer to take the final shot at the convict's head, near the ear. A doctor will then confirm that the convict has died.

9. The convict's family or close friends are responsible for the convict's burial unless the prosecutor says otherwise. If the convict cannot be buried by their family or friends, then the government will organise a burial based on the convict's religious beliefs.

10. The prosecutor must write and sign a report on the execution, which will be inserted in the official court ruling letter.

About the executioners

1. Fourteen personnel from the police's Mobile Brigade are assigned to an execution, but only 12 are tasked with the shooting, while two others are placed on stand-by.

2. Of the 12 executioners, only one is equipped with a live bullet, while the others have empty ones. None of the 12 executioners know who will receive the live bullet.

3. The reason for the use of only one live bullet is to avoid the inmate's chest being heavily damaged and causing him more pain, according to the police.

4. Police officers in their early 20s are usually selected to carry out the task as they are considered to be physically and mentally fitter than their seniors.

5. The officers selected to be part of the firing squad are given extra training to sharpen their shooting skills.
