A post-mortem examination has taken place and the cause of death was given as a gunshot wound to the chest, police said. There have been no arrests and the murder investigation continues.
While officers believe they know the identity of the 42-year-old man who died, and next of kin have been informed, they await a formal identification.
The incident happened just outside the Bros Bakery in Lordship Lane where Guzel would often sit, eyewitnesses said.
