Prosecuting Homicide

Murder and manslaughter are two of the offences that constitute homicide.

Manslaughter can be committed in one of three ways:

  1. killing with the intent for murder but where there is provocation, diminished responsibility or a suicide pact.
  2. conduct that was grossly negligent given the risk of death, and resulted in death.
  3. conduct, taking the form of an unlawful act involving a danger of some harm, that caused death.

With some exceptions, the crime of murder is committed, where a person:

  • of sound mind and discretion (i.e. sane):
  • unlawfully kills (i.e. not self-defence or other justified killing)
  • any reasonable creature (human being)
  • in being (born alive and breathing through its own lungs)
  • under the Queen's Peace
  • with intent to kill or cause grievous bodily harm.

There are other specific homicide offences, for example, infanticide, causing death by dangerous driving, and corporate manslaughter.

Fake policeman who was filmed smothering victim found guilty of murder


A fake policeman has been convicted of murder after he was filmed by a laptop camera smothering and suffocating his victim.

Jason Marshall, 28, tricked his victim, Peter Fasoli, 58, into allowing himself to be bound and gagged at Mr Fasoli's bungalow in Northolt on the evening of 6 January 2013.

He then smothered him with sheets of cling film before setting alight to the building to disguise his actions. Although Marshall believed he had killed his victim, Mr Fasoli may have still been alive before the fire started.

Marshall, who had pretended to be an undercover police or MI5 officer during the course of the murder, fled the country and went on to commit another murder in Italy three weeks later. A relative discovered the footage on his uncle's laptop in November 2014 leading to Marshall's extradition and arrest.

He was found guilty of murder and arson by a jury at the Central Criminal Court today (9 August 2017).

Sally-Anne Russell from the CPS said: "Jason Marshall murdered Peter Fasoli after being invited into his home.

"He suffocated him before lighting a fire to cover his tracks.

"If it hadn't been for Mr Fasoli's own laptop footage, Marshall may have escaped justice.

"That video, which was extremely disturbing, clearly showed Marshall's true intentions and undermined any false account he could give, leading to today's guilty verdict.

"Our thoughts are now with Mr Fasoli's family."

Marshall, formerly of Forest Gate, east London, is due to be sentenced at a later date.
