The "devastated" family of an 18-year-old shot dead in Greenwich one year ago are appealing for information as detectives release CCTV images and footage.

Ethan Nedd-Bruce, who lived in Charlton, was gunned down from a moped outside Collins House on Armitage Road, in what police believe may have been a case of mistaken identity connected to a "turf war" between two local criminal groups.

On the anniversary of his death, his mother Cherie Nedd called on those who may be "fearful" in the community to come forward to help identify her son's killer.

She said: "I believe the answers are in the community.

"There must be someone who knows what has happened, and they probably are just feeling fearful and not wanting to talk about it but somebody must have seen something that would give a clue as to what happened.

“Our hearts are completely broken. Lives have been shattered never to be repaired. Finding the murderers will not bring Ethan back, but it will help to give the family closure that we so deserve.

“We have to put a stop to people thinking they can literally get away with murder.

"Please! As a mother I have lost my only son...I urge you to help us in this time. This violence has to stop.”

Ethan had been involved in an altercation with a group of males minutes before outside a chicken shop on Woolwich Road.

As he fled, the males pursued him into Armitage Road on a motorbike and silver Ford Kuga car, where he was attacked and killed at around 9.25pm.

Officers initially believed that he had suffered a stabbing injury, but a post mortem later revealed it was caused by a gunshot.

Police today released CCTV images of a beared white male holding a mobile who they believe he walked past the chicken shop where Ethan was in the moments prior to the first attack.

They also released footage of two vehicles the attackers used that evening; a motorbike with a rider and pillion passenger and the other a silver Ford Kuga with a number of occupants.

Detective Chief Inspector Richard Leonard from Specialist Crime, who is leading the investigation, suggested the victim may have been attacked due a "perceived association" with a criminal group in the area.

He said: "The investigation has indicated that Ethan’s murder was the culmination of a number of linked offences that occurred around the area, what that would suggest to me is that there is a sort of turf war.

"And Ethan was targeted not because who he was but because a perceived association with a group living around that estate. And I think what was actually happening is a message was being sent.

"Whatever the motive in this case, Ethan did not deserve to be pursued and attacked in this shocking manner.

“I believe the answer to who is responsible for this attack lies within the local community and I would urge anyone with information to come forward and speak to my team, or if you are apprehensive about speaking to officers, then through the independent charity Crimestoppers.

“Ethan’s death has left his family utterly devastated and they can only begin the healing process once those responsible have been convicted.”
