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.

Three men convicted for the murder of Sabrina Moss


Martell Warren, Hassan Hussain and Yassin James were convicted today at the Central Criminal Court for the murder of Sabrina Moss on 24 August 2013 in Kilburn. They were also convicted for the attempted murders of Sabrina Gachette, Mahad Ahmed and Edson Da Silva. Simon Baptiste was convicted of conspiracy to cause grievous bodily harm.

Baljit Ubhey, CPS London Chief Crown Prosecutor, said: "On 24 August 2013 a young woman lost her life as a result of needless gang violence.

"Sabrina Moss was celebrating her 24th birthday, enjoying the end of an evening out with friends when her life was snatched away.

"These defendants were targeting members of a rival gang and spent the hours leading up to the fatal shooting in surveillance of their targets. But when it came to firing shots, they didn't care who they hit.

"Before the murder the defendants picked up a shotgun and a machine gun. When they began firing it was at close range and with a complete disregard for human life. They then made their escape in a car driven by Warren.

"Although Warren did not fire any of the fatal shots he knowingly took part in this murder of an innocent bystander. Baptiste left the group before the fatal attack, however, his help with the reconnaissance showed he was guilty of conspiring to commit grievous bodily harm."

Convictions details:

Martell Warren (23), Hassan Hussain (29) and Yassin James (20):

  • One count of murder
  • Three counts of attempted murder
  • Two counts of possession of a firearm with intent to endanger life

Simon Baptiste (29):

  • Conspiracy to cause grievous bodily harm
