The jury in the Mohammed Raja murder trial has been asked not to look at evidence in isolation.
David Waters was summing up the prosecution case at the Old Bailey.
Sussex tycoon Nicholas Hoogstraten is accused of taking out a contract on the life of the 62-year-old landlord on July 2, 1999.
Mr Waters told the jury: "It is important you do not look at the evidence in isolation as there is a cumulative effect coming together from different sources."
David Croke, 60, of Bolney Road, Moulsecoomb, Brighton, and Robert Knapp, 54, of County Limerick, Ireland, are accused of carrying out the killing.
Mr Waters said some witnesses described the killers as in their 30s and one described one man as a teenager.
The witness statements were not consistent. But he reminded the jury of one woman who identified Croke driving the getaway van on a video identification parade.
Mr Waters was due to continue his summing up today.
Hoogstraten, of High Cross Estate, Framfield, near Heathfield, denies murder and conspiracy to murder. Croke and Knapp deny murder.
The trial continues.
