Shooting police officer where evidence primarily cell site

Two days after the shooting of PC Beshenivsky in Bradford her murderer Muzzaker Shah left a council estate in South London where he had been in hiding to travel to Wales. He was assisted by the defendant who with another drove him to Wales. The defendant then rented premises and stayed with Shah for nearly two weeks before the Police laid siege to the flat. After nearly 24 hours the defendant convinced Shah to surrender. A great deal of the Crown’s case relied upon cell site evidence.
