THE family of Adam Ellison, who was stabbed to death while on a night out with friends, have told the BBC they do not know how anybody shielding his killer can sleep at night.

Adam Ellison, 29, was fatally wounded in the neck in the centre of Prescot, after an altercation with two people on a motorbike.

Despite a series of arrests during an investigation that spanned more than four years, and the offer of a £24,000 reward, no one has been convicted over the November 2017 attack.

He was stabbed by the pillion passenger of a green and white Kawasaki motorcycle in Market Place.

Our Adam

Tonight BBC One will feature the documentary Our Adam to shine a fresh light on the case.

His sisters Joanne Evans and Nicola Moore feature in the appeal

Nicola told the BBC: "He was horrendously taken from us.

"You want to shout it from the rooftops 'how dare you walk around the streets'.

"You've murdered somebody. People know you have done it. How can they sleep at night?

"If it can happen to Adam - it can happen to anyone."

The documentary describes how the green and white Kawasaki connected with Adam  fatal stabbing went back to the Hillside Avenue estate in Huyton.

The pillion passenger sped off on the motorbike after stabbing Adam.

'People on that estate know who was riding it'

Detective Chief Inspector Cath Cummings, the senior investigating officer from Merseyside Police, revealed to the programme that the motorbike was ridden to the Hillside estate after the murder and has never been seen again.

She said:  "People on that estate know who was riding it, they know where that bike went and they know who was on it," she said.

"This isn't going away… this is by no means a cold-case murder investigation." 

What happened on the night Adam died?

The Kawasaki motorbike rode into Prescot in the early hours and at about 12.30am the pillion passenger got off the bike and looked through the Old Mill pub.

Detectives believe he was looking for someone.

The passenger got back on the rear of the bike and it was driven "at speed" down Eccleston Street to the junction with Market Place where it crossed Adam's path.

Adam, who was with a group of friends and cousins, shouted at them and the bike stopped, with the passenger getting off, heading towards Adam and stabbing him.

'We know the answer lies in our communities' 

Detective Chief Inspector Cath Cummings told the BBC show that the passenger got back on the motorbike and it then travelled back to the Hillside Avenue estate.

Police have made numerous appeals to trace the Kawasaki but it has never been found.

In a statement, DCI Cummings, who is the senior investigating officer on the case, said: "At the end of this year it will be five years since Adam’s death.

"I know that it has been five difficult years for his family and friends who have tried to come to terms with the sudden, unexpected and shocking loss of a loved one.

"Their agony has been compounded by the fact that, despite an ongoing investigation and a number of lines of enquiry being explored, his killer is still free to walk the streets.

"We regularly meet with Adam’s family and we are equally frustrated that this person is still at large and I know that the majority of law-abiding people will be outraged that they are still free to go about their daily business.

"We know the answer lies in our communities but keeping quiet when you know something is misplaced loyalty that Adam’s killer does not deserve to have. I would appeal to anyone who has got the vital piece of information to search their consciences and come forward.

"If they don’t want to speak to the police then please speak anonymously to Crimestoppers and pass on what you know.

"Charging someone with Adam’s murder and seeing them go to prison does not bring Adam back but it will mean that this family, who have fought so hard for answers, will finally get the justice they deserve.

"I am sure anyone who has ever met Adam’s family, or who watches the programme this evening, won’t fail to be moved by what they have been through.

"Time is never a barrier to justice. Please come forward, tell us what you know and help us to help them."
