It it now known that the 19-year-old took a taxi from west London to Loughton, with new CCTV footage capturing him walking alone on Smarts Lane towards Epping Forest at 00:39 on March 23.
CCTV footage shows the Oxford Brookes student wearing all black and wearing a black satchel bag with a white Adidas logo worn across his lower back.
Det Ch Insp Nikki Beecher said: “Our officers are working extremely hard to piece together the facts in order to build a picture of Richard’s movements on the evening of Monday March 22.
“Latest information suggests he was last seen in Loughton in Essex and we are now focusing our attention here, with specialist search officers from across the Met brought in to assist.
“Our enquiries also continue in the Ladbroke Grove, W10 area where local officers have been carrying out search patrols and also community patrols to gather information from local residents.
“I would once again like to renew our appeal to the public for any information which may assist with our enquiries.
“If you may have seen Richard – particularly in the Loughton area – or have any information at all, please contact police.”
Mr Okorogheye’s mother, Evidence Joel, previously said her son had spoken of “struggling to cope” with university pressures and had been shielding during lockdown as he has sickle cell disease.
He did not take his medication or any money when he left home.
