Khalid Shahenshah, who was the former Pakistan prime minister’s security chief at the time of her assassination, was killed in a drive-by shooting as he left his house in the southern port city of Karachi on Tuesday, police said.
Mr Shahenshah, 45, was riding in Mrs Bhutto’s bullet-proof car when she was killed in a suicide attack in the northern city of Rawalpindi on December 27.
He was expected to be called to give evidence at a United Nations probe into her death.
“He was a key witness in the case and was also interviewed by the Scotland Yard experts who came to Pakistan to investigate her killing,” said Waqar Mehdi, the junior information minister of Sindh province.
“There is a possibility that his killing could be linked to his status as a witness, although investigations are still underway.”
A team of Scotland Yard detectives concluded in February that Mrs Bhutto was killed by a suicide bomb and not by gunfire, backing the previous Pakistani government’s claim the attack was masterminded by Baitullah Mehsud, Pakistan’s top Taliban commander.
