David Ungi is standing trial accused of murdering Vinny Waddington seven years after he was shot dead.
The 18-year-old was shot dead after a crash on Banks Lane in Garston on July 14, 2015. Vinny had been the pillion passenger of a motorbike which was struck by an Audi car at around 8.47pm.
One of three men inside the vehicle fired a shotgun out of the passenger side window, striking Vinny in the chest. He was able to run a short distance before collapsing. The rider of the bike, then 21-year-old Francis Humphries, was wounded by the same shotgun blast but survived.
