sold the van for £15 to an unknown man in a pub earlier in the day, but confessed on 14 August, admitting what had happened and naming his accomplices. Duddy had fled to his native Glasgow but was arrested on 17 August using information obtained from his brother. After meeting his common-law wife for money Roberts moved through Epping Forest then used a tented camp to hide out in Thorley Wood near Bishop's Stortford in Hertfordshire to avoid the huge manhunt. Until the cold winter weather set in he used his military training (he had served as a soldier during the Malayan Emergency) to avoid police capture for three months. A £1,000 reward (equivalent to £19,000 in 2020) was offered for information leading to his arrest. He was finally arrested on 15 November whilst sleeping in a disused airfield hangar on Blount's Farm, Sawbridgeworth near Bishop's Stortford. Roberts was familiar with the area as he had often visited it as a child with his mother. Attackers The three attackers were John Edward 'Jack' Witney, John Duddy and Harry Roberts. Witney (1930–1999) was a known petty criminal with ten convictions for theft. He lived with his wife in a basement flat in Fernhead Road, Paddington. Duddy (1928–1981) was a long-distance lorry driver. He had been in trouble for theft several times when he was younger. Immediately prior to the offence he had started to drink heavily and had met Roberts and Witney in a club. Roberts (born 1936) was a career criminal with convictions for attempted store-breaking, larceny and robbery with violence. He was a former soldier who had served in Malaya. Trial The trial of Witney and Duddy began at the Old Bailey on 14 November but was almost immediately adjourned after Roberts's arrest so that the three men could be tried together. Roberts pleaded guilty to the murders of DS Head and DC Wombwell (but not that of PC Fox), while the other two defendants denied all charges. Only Witney testified in his own defence, saying that he and Duddy were terrified of Roberts. On 12 December 1966, after a trial lasting just six days, the three men were convicted of murder and possession of firearms and sentenced to life imprisonment. The jury took 30 minutes to reach their verdict. The judge, Mr Justice Glyn-Jones, recommended that they serve at least 30 years before becoming eligible for parole. He
