The body of Richard Okorogheye is thought to have been found by police in Epping Forest after he went missing from his family home in west London on the evening of March 22nd.
The family of the 19-year-old, who has sickle cell disease, have been spoken to by officers, who are waiting for formal identification.
Metropolitan Police detective superintendent Danny Gosling said police remain in the area to carry out further searches as they try to piece together what happened to Mr Okorogheye.
But reports of police officer’s initial conduct have been called into question after reminders circulated on social media that his mother’s concerns were not taken seriously at first.
Speaking to Sky News, Richard’s parents Evidence Joel and Newton Okorogheye said officers were dismissive when they reported their son’s disappearance.
She said: “I told a police officer that my son was missing, please help me find him, and she said ‘if you can’t find your son, how do you expect police officers to find your son for you?’
“I was expecting assurance. My son was missing and it broke my heart.”
In a plea for him to come home she added: “It’s my baby, it’s my treasure. He’s my oxygen, he’s my crown. He’s everything to me, he’s the reason why I live, the reason I exist.
“Right now I’m empty, there is nothing to look forward to. He’s taken my breath away from me.”
