The below was an interesting article about the The killing method, the Serbian theory and Barry George's evidences.
The fact that the killing happened so fast outside her door to me could point only to either an execution style murder or an accident, as in any other circumstances they would have forced her inside her house first.
And I am still puzzled as to why BG never dispose of of the coat or the photos in his apartment if we say he was panicking and already disposed of the gun (and potentially all the ammunition or the tools to modify a gun which he must have had in the apartment)
Shadow of doubt?
"
From the outset, there appeared to be two vital clues to the kind of crime this was: the method of killing and the ballistics evidence. As Dando was about to put her keys in the lock to open the front door of her home in Fulham, south-west London, she was grabbed from behind. (The late Iain West, then Britain's leading pathologist, identified a recent bruise to her right forearm.) With his right arm, the assailant held her and forced her to the ground, so that her face was almost touching the tiled step of the porch. Then, with his left hand, he fired a single shot at her left temple, killing her instantly. It was very close to 11.30am. The bullet entered her head just above her ear, parallel to the ground, and came out the right side of her head and into the door, leaving a mark that was a mere 22cm above the doorstep.
For the killer, there were three advantages to such a clinical, one-shot murder. The first was silence. The gases escaping as the gun was discharged, which normally cause the report, instead exploded inside the head, so there was virtually no noise: Richard Hughes, Dando's neighbour, was working at the front of the house and heard a brief, sudden cry, but no gunshot.
The second was that the assailant did not end up covered in flesh and blood. The third was speed - Hughes estimated a gap of only 30 seconds between hearing Dando get out of her car and the latch of the gate as the assailant, his job done, closed it behind him; the police estimated it happened even faster than that."
"But there was another possibility: that a custom-made, smooth-bore, short-range weapon had been used. If the killer planned to put the weapon against his victim's head, and was practised in doing so, there was no need for the long-distance accuracy provided by rifling in the barrel"
"It is conceivable that an armourer had prepared a weapon, bullet and cartridge for the specific task. Ash suggests that a smooth-bore, one-shot assassination weapon could have been fitted inside a mobile phone; in autumn 2000, just such a weapon, concealed in a mobile phone, was removed by German police from a Yugoslav gun dealer near the Swiss border. Dando's neighbour, Richard Hughes, had thought the killer carried a mobile phone; yet all mobile phone records for that area, painstakingly trawled through by police, yielded no relevant information"
"
There were two reasons given by the prosecution for discounting the "Serb" theory. First, that too little time had elapsed between the Radio-Television Serbia bombing and Dando's death; three days was insufficient time in which to plan and execute an assassination. But if, as is more likely, the murder was conceived following Dando's television appeal on behalf of Kosovan Albanians, the murderers would have had three weeks, ample time for preparation. Second, Orlando Pownall QC, for the Crown, told the jury that it could not have been a Serbian assassin because Serbia had not claimed responsibility for the killing: had Milosevic wanted Dando's death to serve as a protest against Nato military action, he or his operatives would have publicised the fact. The most charitable thing to say about this assertion is that it demonstrates an ignorance of Balkan politics and, indeed, the history of the cold war. "Claims of responsibility" are made by groups such as the IRA or Eta. In 60 years, there has not once been a "claim of responsibility" for an assassination carried out by east European secret services."
"Ever the fantasist, Barry George may now be adapting to his notoriety (two tabloid newspapers have advertised tapes of prison "confessions"), but he should be a footnote in this story. Apart from that invisible speck of explosives residue found on his coat, the police found no evidence that he had possessed guns or ammunition in the past 15 years. He had neither expertise in weapons, nor the resources to modify them. He had no car, no money. There was no forensic evidence found in his flat: remarkably, police found no explosives residue there, even though it was assumed that he'd gone home to change straight after the shooting. The two squads of officers, 50 in all, who surveilled his movements for more than three weeks before his arrest gleaned no evidence to assist their case. Dando's neighbours, the only two eyewitnesses, failed to pick out George in an identity parade."
"The conviction hangs on that speck of explosives residue that might, as Mansfield argued in court, have come from almost anywhere. It might have been fireworks, or the coat could have become contaminated while in police custody (it was photographed before forensic analysis, so the possibilities for contamination were considerable)"
