The judicial commission probing Mir Raza Ali's death on Tuesday summoned his business partners, friends, the cab driver who dropped him off and two police officers. Justice Omar Sial of the Sindh High Court, who heads the one-man commission, issued notices to his business partners, Ahmed and Abdullah, his friends Haitham and Raziq, the cab driver Ahsanullah, SDPO Shahrah-e-Faisal Arshad Afridi and SHO Firozabad Adeel Afzal for September 3.

Mir Raza Ali, an IBA graduate and young businessman, was found dead in Karachi's Gulistan-e-Jauhar area on July 29, a day after he went missing. His father consistently maintained that his son was murdered and rejected suggestions that the death was a case of suicide. An autopsy found that the young businessman had been shot in the back.

As per the medical report, marks of violence were also found on Mir Raza's body. The report read that black marks were also found on his body, while injury marks were present on his feet. Blood stains were found on tissues in the lower part of his body. The report also found evidence of a deep injury and fracture in the jaw area.

The Sindh cabinet decided last week to form a judicial commission to investigate the death of the young businessman despite objections from the bereaved family. At the outset of today's hearing, Osama Sheikh, a medico-legal officer who had performed Ali's first autopsy, denied ever discussing suicide and told the judicial commission that the final post-mortem report was issued on August 11 after Mir Raza's exhumation.

He said that the final report was prepared after reviewing chemical reports obtained following the exhumation. The commission noted that the final report differed from the earlier report, including in handwriting. 'What suddenly happened that the report changed?' it asked, questioning whether Dr Osama had prepared both reports and whether a forensic examination should be conducted.
