We urge anyone with any information to contact the police to help catch those responsible. We now ask the media to respect our wishes and allow us the privacy we need to begin to rebuild our lives."
A post-mortem examination on Sunday gave cause of death as a gunshot wound to the chest..

Police and the London Ambulance Service found two women suffering from gunshot injuries and both were taken to London hospitals. Ms Moss was pronounced dead later.
Mr Sandlin said: "I am appealing for anyone who witnessed the shooting, or who saw anything suspicious in the Kilburn area, to call police.
