Fresh appeal to girls after fatal London shooting
A group of teenagers who may hold vital clues to a fatal shooting in south London have been urged to come forward.
Ricardo Cunha, 23, was shot in the head as he looked out of the window of his flat in Elder Road, West Norwood, after hearing a knock at the door.
Detectives have said Mr Cunha, a Portuguese national, may have been the victim of mistaken identity.
Police said a group of girls had been in a play area on the estate at the time of the shooting on 11 September.
The shooting happened when Mr Cunha investigated a knock at the door to his flat in Pondfield House at about 2315 BST.
He had been at home watching television with his girlfriend when the gunman struck.
Det Ch Insp Nick Scola said: "Ricardo Cunha was a young man with no criminal past or connections. We have yet to find a motive for his murder and cannot rule out that this may be a case of mistaken identity."
He said a group of girls had been seen in the play area nearby at 2300 BST and disappeared shortly after the shooting.
Urging them to contact police, he said: "It's vital that we trace a group of teenage black girls that were in the play area on this estate.
"It is inevitable that they hold some important information to our inquiry."
Relatives of Mr Cunha, a Portuguese national, have been trying to raise the £6,500 needed to pay to fly his body to his homeland so he can be buried alongside his father.
Paying tribute to her brother Lily Cunha, 18, said: "He was really supportive, always helping, anything I needed he would just always be there for me."
