A week after the murder of 19-year-old Delaney Brown, police say no-one has come forward to help them with their investigation.
The officer in charge of the case, Det Chief Insp Steve Collin, issued a plea for people provide them with information, saying: “There are people out there who can help solve this investigation.”
He said he believes Mr Brown’s death was “a deliberate act” stemming from a disagreement between two families.
The unemployed teenager, of Bank Close, Hockwell Ring, was cycling along Vincent Road in Leagrave at 4.30pm last Wednesday when he was hit by a car. He died at the scene from a broken neck, and may have been crushed against a garden wall.
A silver BMW 1 Series with the fake registration number WF11 RWV, believed to have been involved in the collision, was found in Morris Close, Marsh Farm, the morning after the murder.
Forensics officers have been working to retrieve fingerprints and DNA evidence from the car, which had been stolen in Hounslow in July.
And yesterday (Wednesday), officers set up a roadblock in Vincent Road to speak to motorists on the one-week anniversary of the murder.
They also put up appeal posters reminding people that even the smallest piece of information could be the key to unlocking the case.
Detectives believe there was more than one person in the vehicle that killed Mr Brown, and that the vehicle might have been “circulating” around Leagrave before the fatal collision.
They also and that there may have been someone with the 19-year-old, but that person has not yet been traced.
The victim was in Luton town centre prior to the attack and had taken the train out to Leagrave.
DCI Collin also revealed Mr Brown had been involved in crime, specifically robberies and possession of weapons, but said he did not believe his death was linked to the offences.
“There are a lot of people who knew Delaney and the kind of person he was, or was perceived to be,” he said.
“We need them to come forward and speak to us or Crimestoppers.
“We have a suspect in mind but we cannot name them at this time.
“I believe that person is local and will be known in the community.
“There has been a lot of rumour but as yet we have not had anyone come forward who is prepared to give evidence to support this investigation.”
DCI Collin said Mr Brown’s father, three brothers and grandparents were “devastated” and that the family had been left “in despair” by his murder.
Asked about the dispute the victim had been involved in, he said: “There seems to have been a dispute between two families that started off as quite close friends, I’m told.”
