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.

Prosecuting Violent Crime

Violent crime covers a wide range of offences including:

These crimes are extremely rare, they account for only about 1% of all crime. Yet they cause significant harm, both to individual victims and their families in terms of physical injury and psychological trauma, and to society more widely in terms of fear. We are committed to prosecuting violent crimes efficiently and effectively.

Decision to Charge

Once the Police have completed their investigations, they will refer the case to the Crown Prosecution Service for advice on how to proceed. We will then make a decision on whether a suspect should be charged, and what that charge should be.

Man who beat a child to death for losing a trainer is guilty of murder


A man who beat his girlfriend's five-year-old son to death for losing a trainer has been found guilty of murder.

Marvyn Iheanacho, 39, [01/06/1978] from Hounslow, was convicted of murdering Alex Malcolm today (21 July) at Woolwich Crown Court after a trial.

Alex suffered fatal head and stomach injuries after being attacked in Mountsfield Park, Hither Green, on the evening of 20 November 2016.

He was taken home by Iheanacho and then to hospital but died two days later after an unsuccessful brain operation.

Rob Davis, of the CPS said: "Only Marvyn Iheanacho knows how Alex was fatally wounded, but it is certain his anger boiled over at some point that day.

"The prosecution case was that a witness heard Iheanacho swearing at a child over a shoe that had been lost in the nearby park. He was heard repeatedly and violently punching a gate.

"Later in the park another witness saw Alex lying prone on a bench. CCTV showed Iheanacho carrying Alex's body to a cab office.

"His actions that day tragically ended a young boy's life, and deprived a mother of her son.

"His efforts to cover up what really happened, first to Alex's mother by claiming Alex had simply fainted and hit his head, then by lying and repeatedly changing his story to police, show his greatest concern was for himself.

"Our thoughts go to Alex's mother and family and we hope today's conviction brings them some sense of justice."

Iheanacho will be sentenced on 25 July.
