They said the attorney general would demand the death penalty for him.

The sources said a three-judge panel would try the man, of African nationality, at a Yanbu court after they receive the complete file of the case. The attorney general demanded that the man should be beheaded under Shariah if the charges that he had allegedly killed, raped and burned the bodies of the three women are proven.

The killer used to pick housemaids without any legal identification as his victims to avoid detection. He would torture his victim, rape her, disfigure her body and hide it.

The police had been looking for him for about four years before finally arresting their prime suspect after a tipoff from his own son, who was caught on charges of begging.

According to sources from the Prosecution and Investigation Commission, investigators believe that the man was mentally ill, but psychiatrists are certain that he knew what he was doing when he allegedly committed his crimes. He has reportedly admitted the murders to the court.

Police investigations found him to be carrying many forged identities and discovered pictures of housemaids in his mobile phone, including the photograph of one of the victims.

The police started monitoring the man after his son told them that he saw his father stabbing an Indonesian housemaid on the street.

The bodies of the victims were found in three different locations in the city.
