The killer of Pakistan's first Prime Minister was being paid hundreds of rupees every month by the Pakistani government itself. The murder conspiracy is still unsolved.
The place where former PM Benazir Bhutto was killed, was washed by the fire department before police could gather evidence. And just a month later, people allegedly connected to the case started dying one-by-one. The assassination case is still a mystery.
Is the case of the gun attack on Imran Khan headed towards a similar fate? Will the real story ever be known?

The Islamic country's first premier Liaqat Ali Khan was shot dead in the middle of a big public event on 16 October 1951. Here are the five things which still do not add up in the case.
The most curious thing is that the Pakistani government was giving the assassin - an Afghani named Said Akbar - Rs 450 every month as welfare allowance. The payment had been started by the British colonial government.
On the day of the murder, the assassin was sitting right in front of stage, on a seat meant for CID police officers. In the 70 years since, it has never been ascertained how the assassin got access to a front-row seat at the event.
The shooter was apparently alone, but police shot and killed him instead of capturing and questioning him. Strangely, the first investigative committee that the Pakistani government created did not look into the murder plot, but focused on security failure.
The murder case of Benazir Bhutto was full of even more bungled-up actions, unanswered questions, and mysterious deaths. The former PM was killed on 27 December 2007. The attacker first shot at her, then blew himself up.
Shockingly, the fire department hurriedly washed the crime scene, ruining important evidence. Subsequently, Bhutto's security guard, who had made suspicious gestures at the event, was killed in 2008. Two suspects who allegedly helped the assassin were killed a month after Bhutto's death.
Two other men, who had allegedly helped with preparation and transportation of the suicide vest, were killed in 2008 and 2010. Chillingly, a government lawyer who had claimed to have been making progress in the case, was killed in 2013.
Soon after the assassination, five suspects had confessed to being part of the murder plot. They later withdrew their confessions, but police gathered proof against them, including DNA evidence. However, the court said that there had been procedural errors in the collection of evidence. Subsequently, all 5 accused were acquitted.
Only two police officials were punished for ordering washing of the crime scene. Interestingly, former President of Pakistan, Pervez Musharraf was also charged in the case, but proceedings stalled as he was in self-exile.
While odd happenings in the two murders might only hint at the possible role of Pakistan's so-called 'deep state', Imran Khan is not being subtle with his allegations.
Imran Khan's party PTI has blamed top political and military leaders for the gun attack during a protest march. Khan has openly accused Pakistan's current PM Shehbaz Sharif of masterminding the attack. He has also accused federal interior minister Rana Sanaullah, and Maj Gen Faisal Naseer, who is the head of counter-intelligence at spy agency ISI.
While Imran Khan's party has claimed inside information for the allegations, it is yet to offer any evidence. Also, the shooter has reportedly claimed that he was working alone.
Imran Khan has been attacked while trying to return to power after having a fall-out with the Pakistani military. His situation is frighteningly similar to the circumstances in which Benazir Bhutto was killed. What happens till the next general elections might decide whether Pakistan falls further into the abyss, or begins to climb out.
