Last year, the bbc publicly identified a sixth Suspect Matthew white, who died in 2021 and revealed multiple failures by the met to properly investigate him. Now, stephens mother, baroness doreen lawrence, gives her first interview about the new evidence and the met� s response. We knew there was five, possibly six. Now we know that there were six. And the one thats just passed away, hes probably the key one who probably caused Stephens Murder and they did nothing about it. We showed not everything possible was done before the Murder Investigation was closed four years ago. Baroness lawrence now has a personal message for the met commissioner, sir mark rowley. Theres still lines of inquiries for them to follow up on
