Police launched a murder investigation after Junior George Nelson’s remains were found in undergrowth near railway lines at the back of Rabournmead Drive in Northolt on March 14, 2016.
Junior was first reported missing after being last seen at his home address in Aldershot Road, Kilburn, on August 15, 2015.
Officers believe that he remained in the Brent area until that evening before he travelled towards Wembley.
Mobile phone analysis showed he was at Stonebridge Park at around 10pm that evening, however his phone has never been recovered.
Police believe that prior to his disappearance, he was being taken advantage of by those involved in dealing illegal drugs in Kilburn.
The case became a murder investigation after his body was found.
Four people were arrested following an initial investigation, but all were released without charge.

“We remain committed to finding those responsible for Juniors’s death but need the public’s help. There are people amongst the community, in particularly the Kilburn area, who know what happened to Junior.
“A lot can happen in ten years. Allegiances can change and maybe you felt unable to talk to us at the time, for whatever reason, but you are now in a position to do so. Now is the time to come forward.
“We understand that those with information may be concerned, but I would urge anyone who can help to come forward and help give Junior’s family the justice they deserve.”
Anyone with information that could aid the investigation is asked to contact Crimestoppers, an independent charity, anonymously.
