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.

Conviction for murder of Kiyan Prince


Following a retrial, a jury at the Old Bailey today convicted a 17-year old youth for the murder of 15 year-old Kiyan Prince who was stabbed outside his school, the London Academy in Edgware, in May 2006.

Jaswant Narwal, District Crown Prosecutor at the Old Bailey Trials Unit said:

"As well as the deep loss felt by Kiyan's parents this senseless knife killing has shaken an entire school and community. Knives, including penknives, are not toys and we prosecuted for murder as we would if a gun had been used. No child should live with the risk of seeing their friends frightened, wounded, or killed and certainly not outside their own school.

We thank the Prince family for their determination to follow us through these trials and also the pupils and teacher from the London Academy who bravely gave evidence a third time."
