ISLAMABAD, May 6: Law enforcement agencies investigating the killing of FIA special prosecutor in the Benazir Bhutto murder case have no record of the outfit believed to be behind the attack, sources told Dawn on Monday.

The prosecutor, Chaudhry Zulfiqar Ali, was shot dead at Sector G-9/1 when he was going to office on May 3.

An Urdu pamphlet found at the crime scene and purportedly written by Mujahideen-i-Islami stated: “Those who help punish the Mujahideen would meet the same fate.”

However, the police and intelligence agencies have no record or details about the organisation.

The sources said there was a possibility that the killers had used the name of the outfit only to divert the investigators to a wrong direction.

It is premature to establish whether any militant organisation was behind the killing or there was some other motive.

The joint investigation team (JIT) is probing the murder from all angles, including personal enmity, rivalry and any dispute.

An officer close to the investigation said the accused persons in the Benazir murder case would not get any benefit from the killing of the public prosecutor who had already cross-questioned all the suspects and completed the court proceedings in 2010.

In the meantime, the investigators are facing difficulties to trace the taxi (Suzuki FX) in which the attackers had escaped after killing the prosecutor.

The excise and taxation authority has no record of the registration number. Normally, the registration number of a vehicle used in such an activity is replaced, said sources in the police.

“However, the excise and taxation offices in Karachi and Gilgit are checking the numeric number of the registration plate to trace the whereabouts of the vehicle,” the sources said.

They added that the first two alphabets of the registration number were matching with the ones issued by ETO Gilgit and Karachi.

Another officer close to the investigation said chances of survival of one of the attackers injured from the firing of Mr Ali’s gunman - a Frontier Constabulary personnel - were meager.

“We found excessive bleeding at the spot and in such a condition the survival of an injured is impossible,” he said.

Shortly after the escape of the attackers, all the hospitals in the twin cities and nearby towns were alerted with the instruction to inform the capital police if they received any patient with bullet injuries, the officer said.

But no such person was brought to any hospital since Friday.

“There is a possibility that he has died or got medical assistance in hiding,” he added.

However, the investigators collected blood samples from the spot and sent them for DNA test.

Similarly, a Sindhi cap found at the spot along with a mobile phone and a pistol was also sent for the DNA test.

The investigators are hopeful that the DNA test will help them establish the race of the attackers, he added.

The sources further said the JIT was working on the mobile phone to trace the attackers.

However, it did not carry much detail, they added.

It seems that the attackers had bought the mobile and SIM recently, they said.

The JIT also found two eyewitnesses, a policeman and a civilian person.

The policeman helped the JIT in drawing sketches of the attackers. However, the sketches do not match with the ones available in the police record.

The other eyewitness was reluctant to help the police in fear of being targeted.
