The Shepherd's Bush murders, also known as the Massacre of Braybrook Street, involved the murder of three police officers in London by Harry Roberts, John Duddy, and John Witney in 1966. The officers had stopped to question the three men as they were sitting in a car on Braybrook Street, near Wormwood Scrubs prison. Roberts shot dead Temporary Detective Constable David Wombwell and Detective Sergeant Christopher Head, whilst Duddy shot dead Police Constable Geoffrey Fox. The three men went on the run, initiating a large manhunt. All three were eventually arrested and subsequently sentenced to life imprisonment. Duddy died in prison in 1981. Witney, the driver of the criminals' vehicle, was also convicted of the murders; he was released from prison in 1991 but was killed in 1999 in an unconnected incident. Roberts became one of the longest-serving prisoners in British history, serving 48 years before his controversial release in 2014. Public sympathy for the families of the victims resulted in the establishment of the Police Dependants' Trust - now amalgamated into the charity Police Care UK to assist the welfare of families of British police officers who have died in the line of duty. Murders On 12 August 1966, a Metropolitan Police crew in an unmarked Triumph 2000 Q-car, registration plate GGW 87C and call sign "Foxtrot One One", was patrolling East Acton (although the incident was always reported by the media as occurring in Shepherd's Bush) in West London. Detective Sergeant Christopher Tippett Head, aged 30, and Temporary Detective Constable David S Bertram Wombwell, aged 25, were both members of the Criminal Investigation Department (CID) based at Shepherd's Bush police station in F Division, which covered the Metropolitan Borough of Hammersmith. Their driver was Police Constable Geoffrey Roger Fox, aged 41, class 1 advanced driver and beat constable who had served for many years in F Division and frequently acted as a Q-car driver due to his vast local knowledge. All three officers were in plain clothes. At about 3:15 pm, the Q-car turned into Braybrook Street, a residential road on the Old Oak council estate which on one side bordered Wormwood Scrubs and Wormwood Scrubs prison. The officers spotted a battered blue Standard Vanguard estate van, registration plate PGT 726, parked at the roadside with three men sitting inside it. Since escapes were sometimes attempted from the prison with the assistance of getaway vehicles driven by accomplices,
