Kennedy, William Henry & Browne, Frederick Guy
On 27 September 1927 at about 4 am William Henry Kennedy and Frederick Guy Browne were on the Romford to Ongar road in Essex when they were stopped by PC Gutteridge. They were driving a Morris Cowley car which they had stolen earlier from Billericay. PC Gutteridge had got off his bicycle and was standing to the side of the road. As the car approached he indicated with his lamp for them to stop but they ignored this and drove past. The policeman immediately blew on his police whistle and the car stopped.
He approached the drivers window and started to ask questions. He took out his notebook and began to write in it when Browne fired two shots at the policeman. Both shots hit him in the face and PC George William Gutteridge staggered back and fell down. Both men got out of the car and walked over to where the wounded policeman was lying injured. Browne stooped down and fired a bullet into each of the policemans eyes killing him.
His body was later found in the lane two hours later. It was thought that he had stopped a motorist to question him about the car and was shot. The car had been reported earlier as stolen. It was later found abandoned in London with bloodstains on the bodywork and an empty cartridge case on the floor. Four months later whilst interviewing Kennedy's accomplice Browne about another stolen car police found a Webley revolver in his garage. This gun was proved to be the same one which had killed PC Gutteridge. Knowing that Browne and Kennedy were partners the police arrested Kennedy who quickly admitted that he had been in the car on the day PC Gutteridge was killed, he said that Browne had fired the shot.
They both appeared at the Old Bailey in April 1928 and were found guilty.
While waiting for sentence to be carried out Browne tried to commit suicide three times, once by hanging himself and then by cutting his throat. He even tried to go on a hunger strike and had to be force fed. He was not sucessful and both were hanged at the same time on 31 May 1928, Browne was hanged at Pentonville and Kennedy at Wandsworth
