The court heard Danielle was a victim in a gang feud
A man accused of murdering Danielle Beccan filmed himself in a rival gang area bragging "I'm a real killer" before she was shot, a court heard.
Junior Andrews used a mobile phone to record himself walking in the St Ann's area of Nottingham boasting about how brave he was to do so, jurors heard.
Mr Andrews, 23, shouted: "I've been, I've sawn (sic) and I've conquered."
Mark Kelly, of The Meadows, Nottingham, and Mr Andrews, of no fixed address, deny murdering the 14-year-old.
She was shot as she walked home from the city's annual Goose Fair with a group of friends in the early hours of 9 October last year.
The prosecution say Danielle, from St Ann's, was the "innocent victim" of a drive-by shooting, allegedly carried out by members of the Waterfront Gang, based in the rival Meadows district of Nottingham.
Birmingham Crown Court heard at an earlier hearing that Andrews and co-defendant Mark Kelly, 20, were both from the Meadows and allegedly members of the Waterfront Gang.
The court was told he was wearing a hood and had what looked like a cannabis joint in his mouth in the video.
Mr Andrews filmed himself making what appears to be a W sign with his hand, allegedly the mark of the Waterfront Gang.
The prosecution said he was a front seat passenger in a gold Citroen Xsara car which was driven by Kelly into the St Ann's area of the city shortly after midnight on 9 October to carry out the shooting.
The trial continues.
