A fantasist who tricked his way into a loner’s home before killing him, was only caught two years later when a horrified relative discovered footage of the murder on a computer hard drive, a court has heard.
Jason Marshall, 28, posed as an undercover police officer, when he attacked computer repairman, Peter Fasoli, 58, in his bungalow in west London.
Afterwards Mr Marshall set fire to victim’s home in order to cover his tracks and the death was put down to an accident.
But two years later when Mr Fasoli’s nephew was sorting through his belongings, he was horrified to discover a computer file containing CCTV footage of the entire event.
On the opening day of his trial at the Old Bailey, Mr Marshall, was described as a “calculated and determined” killer.
Prosecutor Edward Brown QC warned jurors that they would be asked to view the video, which showed the actual killing itself.
He said: “The issues in this case are such that you will need to watch what on any account is very disturbing evidence.”
The court heard that the footage featured the final hours of Mr Fasoli’s life, as the Classic FM radio station played in the background.
The defendant first made contact with Mr Fasoli via a gay social networking site in December 2012.
But after entering his home he invented the persona of a “law enforcement operative” and sought to dominate and ultimately murder his victim.
Mr Brown said: “There is a telling feature of this case – whilst the defendant sought to tempt the deceased into thinking their encounter that night was to be sexual in nature, the sexual element of the night’s events played only a short part early on and soon was superseded by physical domination and then violence.”
After Mr Fasoli’s death an investigation concluded it had been an accident and he had died in a fire sparked by a faulty light which may have fallen onto his bed.
But Mr Brown said: “The fire was intended to hide a terrible crime. Peter Fasoli was killed intentionally. He had been subjected to a calculated and determined attack by this defendant whom he invited into his home.”
Mr Brown went on: “The fire was set by this defendant in an attempt to disguise what truly happened – and the defendant Jason Marshall very nearly succeeded in escaping justice.”
The harrowing footage of the killing was recovered by Mr Fasoli’s nephew Christopher Murgatroyd, when examining his uncle’s fire-damaged computer, in November 2014.
Expecting to find his uncle’s research on their family tree, Mr Murgatroyd was horrified to discover that he was actually watching his violent death, jurors were told.
Marshall, of East Ham, in east London, denies murder and the case continues.
