The sister of a man shot dead by looters during the Croydon riots has begged the public break down a “wall of silence” and bring her brother’s killers to justice.

Father-of-four Trevor Ellis, 26, died on August 9, 2011, a day after being shot in the head in Duppas Hill Road as disorder tore through the town centre.

Despite the Metropolitan Police making nine arrests and offering a £20,000 reward to help convict his killers, no one has been charged with his murder.

His family will gather by his graveside tomorrow to mark the five-year anniversary of his death and renew their appeal to catch his killers.

His sister Siyreta Ellis, 32, said: “Every year we go down to the cemetery with the family and celebrate his life. We don’t do anything too extravagant because it is hard to know his killer is still out there getting on with their life as normal.

“Him not being here and the change that it has made in our lives [is the hardest thing.] His children miss him, his mother misses him.

“It is hard knowing local people have done this and they could be walking past us on a daily basis but we don’t know. It is hard.”

Police believe Mr Ellis, of Brixton Hill, died after a high-speed chase involving two cars, including one in which Trevor was a passenger.

The friends he was with that night, Blaze Aitcheson-Daley, 22, and Tyrone Cooper, 26, were both convicted of burglary and handling stolen goods in 2012.

It is believed the three became involved in a confrontation with nine others, culminating in the pursuit along Scarbrook Road and the Croydon flyover and into Duppas Hill Road, where Mr Ellis was gunned down.

Trevor Ellis was killed on August 9, 2011

Speaking to the Croydon Guardian on the fifth anniversary of the riots, Mr Ellis’s sister pleaded for anyone with information to imagine losing a loved one to murder and “speak up”.

She said: “At the end of the day his life was taken unnecessarily and his friends and family have been left behind.

“More could have been done [to catch his killer.] Even at the time it happened I don’t think enough was being done.

“There is this big wall of silence. People don’t want to speak. People do know, you know people know and it is not a case of knowing, it is a case of proving it.

“For the people out there who know what has happened: speak up.

“No one would like this to happen to them and a lot of people don’t want to speak until these things happen to them themselves, but people need to break this wall of silence.”

The fifth anniversary of the riots has shone the spotlight once more on losses suffered by businesses in the carnage and the progress the town has made since 2011.

But Mr Ellis’s family feel no headway has been made into finding those responsible for his death.

While his whole family were left devastated by Mr Ellis’s death, his young children were hit the hardest, said Ms Ellis.

Kyron, nine, Anthony, seven, Miami, six and Ciara, five, are being raised with the help of their grandmother and other family members, who focus on keeping his “fun-loving” and “family-orientated” spirit alive.

Ms Ellis said: “As a family we have to try that little extra bit harder to work with them and try and keep my brothers memory alive and let them know where they are coming from and what they are about.

“He was quite well-liked, he was fun-loving and very family orientated because he had children as well and he was good with his nieces and nephews.

“Most people didn’t have a bad thing to say about him.

“I miss his presence, I miss his voice, his antics. I miss the banter and the arguments. I just miss my brother.”
