Jean and Philip Bacon with their cuttings book about Philip's dad Geoffrey

The grieving son of 90-year-old murder victim Geoffrey Bacon is convinced a renewed police appeal will finally uncover the “piece of garbage” who left him for dead three years ago in an attack that shocked the nation.

War veteran and retired postman Geoffrey Bacon was brutally attacked by a vicious thug on his doorstep and died from his injuries three months later, broken mentally and physically by the crime. The villain got away his out of date bus pass and £40.

Now son Philip Bacon, of Manor Road, Tankerton, hopes the £40,000 reward put up by the Metropolitan Police and The Sun newspaper will entice someone to grass on the killer.

The frail pensioner was attacked from behind as he returned from shopping to his Camberwell flat. He was thrown to the floor, shattering his hip and punched in the face.

After ransacking the second floor flat, the robber made off with the out of date bus pass and £40.

He spent three months in hospital and a care home in Westgate-on-Sea where he died from his injuries.

sandra hembery (med-edThe tragedy made national headlines and the renewed appeal, on the third anniversary of Mr Bacon’s death, April 26, 2010, has again sparked nationwide condemnation.

Philip Bacon said: “The trouble is it all comes back. That poor man got knocked to the ground, stamped on and left for dead. Dad had been a fit and healthy man for 90. If it wasn’t for this piece of garbage he would still be alive.

“What makes me so angry is that if the attacker had asked my dad for money, he would have given him some. “

"This new appeal brings it all back to life again, someone must know something.”

Jean spoke of her father-in-law’s popularity in the area of south London that he loved so much. His daily stroll became even more important to him after his wife Edith died in 2005.

She said: “He loved his balcony which he filled with flowers and he would stand there waving to people. He was very well known in Camberwell. He loved painting and joined the post office art club when he worked at Mount Pleasant.

During his war service, Mr Bacon joined the Royal Engineers as a mechanic and became a respected driver in the Royal Artillery. He chauffured Eisenhower in France and was described by a senior officer as a first class, reliable driver.

“When dad was in hospital we asked if anyone had followed him. He said not. We think the attacker went ahead of him to the floor above and waited for him until he returned from shopping.”

Philip said: “ Unfortunately there was no CCTV.

“I can honestly say the police have been absolutely marvellous. One officer said to me that he dealt on a daily basis with tough crime, but my dad’s attack had really struck a chord with the officers.

Det Insp Nathan Eason said: “ Geoffrey was an honest, decent man who braveley served his country. He had worked all his life and had earned the right to a peaceful and safe retirement.

“He did not deserve to have it taken from him in a cowardly attack.”

Philip said: “Something will come of this appeal I’m certain.

“You have got to be positive and if they do catch him I hope they throw the book at him so it acts as a deterrent. It could have been anybody’s dad.”
