A former British Airways steward was found guilty today of murdering his partner in a Travelodge hotel room.
Glenn Rycroft was a prolific conman who had previously cheated friends and colleagues out of more than £200,000, the Old Bailey heard.
He battered Gareth MacDonald over the head with a fire extinguisher at the hotel at the M4 Heston services in September 2007.
Mr MacDonald, a 30-year-old father of three, had left his wife and children to move in with Rycroft in Rhewl, North Wales, after meeting him on the internet.
But the victim had started to become suspicious of his lover after money started going missing from his bank account.
Detectives believe Rycroft had targeted MacDonald to cheat money out of him in the latest of his scams.
Detective Sergeant Nick Mason said: "Gareth MacDonald and his family had money and Glenn Rycroft obviously realised that. It was another gravy train for him.
"It is quite obvious that Rycroft is motivated by greed and he is the type of person who will do anything to get his hands on some money."
Rycroft, 33, originally from Salford, Greater Manchester, denied murder, claiming he planned to marry Mr MacDonald and would never harm him.
He claimed a rent boy must have killed him while he was out of the room but jurors rejected his story and he now faces a life sentence.
Sentencing was adjourned until tomorrow.Reuse content
