Following a live appeal from DCI Dave Whellams on BBC’s Crimewatch earlier this week, officers are still keen to hear from anyone with any information relating to the murder of Corey Junior Davis.
Corey was shot at close range at around 15:08hrs on Monday, 4 September 2017 while socialising in a playground area in Moore Walk, E7. He died in hospital the following day.
His 17-year-old male friend also sustained potentially life-changing injuries to his leg. He was recently discharged from hospital and now faces a long rehabilitation process.
There have been no arrests to date.
The CCTV consists of a still image of a metallic grey 2011 Range Rover Sport HSE TDV6 captured at around 14:53hrs, just before the murder, on Wyatt Road near the junction with Upton Lane, E7. The windows are dark tinted from behind the driver's seat to the back of the vehicle.
Moving CCTV footage shows the vehicle shortly after the murder, fleeing the scene of the crime at around 15:15hrs and driving erratically on Romford Road in a northbound direction towards the A406 North Circular Road.
Detectives have released details of the car - which they have established was stolen at around 01:00hrs on 24 August 2017 from Haverhill Road, Balham, in the hope of triggering the memories of members of the public who might have seen it in the intervening time or since the murder itself.
The first part of the registration plate displayed at the time of the shooting was D11, while the original index at the time it was stolen was EY11 XSG. Officers have also revealed details of the car's unique vehicle identification number (VIN) which acts as its 'fingerprint'. This is SALLSAAG3BA292779 (the last six digits are the chassis number) and its engine number is 0534374306DT.
The investigation team has not issued the full number plate that was on the car on the day of the murder as it was cloned from a legitimate Range Rover sport.
Detective Chief Inspector Dave Whellams of the Homicide and Major Crime Command, lead for the investigation, explained:
"We have reason to believe this car could still be out there - someone could have bought it in good faith for instance having no idea that they have bought a stolen vehicle.
"I would be grateful if anyone who has bought an identical make and model of car since 4 September 2017 could check its VIN number. The VIN number can usually be found by looking from outside the vehicle at the lower left side of the windscreen, in the driver's side door jam or under the bonnet. Please contact us urgently if it matches the number we have given out. The engine number is also readily accessible to check.
"It is also possible that a garage or scrap dealer could have inadvertently worked on the whole vehicle or parts of it without realising it had been used in a murder. Again I would urge people in this sector to think back over the last month and check their records.
"Any information will be treated in the strictest of confidence - it is the persons who used it on 4 September that are our sole interest at this point."
DCI Whellams also wants to hear from anyone who has any more information on the car in the ten days after it was stolen - as well as on the day of the murder itself.
He said: "Did you notice any vehicles like this parked in a street near you in the last week of August 2017 that you weren't used to seeing, perhaps for a few days after 24 August 2017?
"Or did you see it in the Wyatt Road or Romford Road area around 3pm on 4 September 2017, the day of the murder?
"We have previously released moving footage showing the Range Rover speeding past a bus in Romford Road at around 3.15pm that day, only minutes after the shooting. If you were on that W19 bus, we would like to hear from you.
"We are releasing these images in tandem with a high level of detailed information on this vehicle in the hope someone out there can provide information that proves critical to progressing our investigation."
DCI Whellam added that his team had been working tirelessly over the past months to sift through the evidence and piece together the events leading up to Corey’s murder and any possible motive.
"Corey was a teenager of 14 who was seen as being potentially vulnerable by older, hardened gang members who wished to draw him more fully into their world from the periphery of it.
"His mother was very aware of the risk and took steps to distance him from this environment, moving him from the local area and taking all the measures she could in an effort to protect Corey from that danger.
"She, like us, is desperately seeking the community's help to unlock the causes of these tragic events and bring those responsible to justice. Anyone who feels they cannot contact police directly can go to Crimestoppers in complete assurance of anonymity."
Specially trained police liaison officers have been supporting Corey's family since the day he was fatally wounded. Corey had been living with his uncle in south London for some months, but at the time of the murder was staying at his grandfather's Forest Gate flat, just yards away from the playground where he was killed.
Corey's mother Keisha McLeod, 38, her daughter and Corey's sister, Roshane Newman, 23, and his uncle, (Keisha's brother) Kadeem Phipps, 24, have all joined together in the appeal to plead for any help the public can provide.
Keisha McLeod, said: "CJ was a fun, loving, kind, handsome young boy, just 14 years old. He loved to make us laugh and dance with his funny routines. He had real talent and such potential.
"I'm appealing directly to the community. If my son's life has been taken for the wall of silence to be broken, let it be broken today. Please don't ignore my voice, please don't ignore my pain.
"The murderer of my son is still out there. Please help the police to help me and my family."
