Police will return to a murder scene today, one week after a teenage university student was shot dead.
Joseph Burke-Monerville was fatally wounded in Clapton, East London last Saturday as he sat in a car with his two brothers in what police believe was a case of mistaken identity.
The 19-year-old, from Islington, was rushed to hospital but later died.
No arrests have been made but police say two suspects were seen running from the scene.
Today detectives will be appealing to anyone who may have witnessed the incident to come forward.
