Lets look at the facts.
Mark Alexander told everyone who enquired that his father Samuel had gone to stay with friends in London. If this is true who are these friends? If what he claimed was totally false why did he lie?
Mark Alexander sent out Christmas cards to his neigbours in his father's name. Why did he do that?
Mark Alexander took delivery of concrete and had it laid over the exact spot where his father had been buried. Is that a coincidence too far?
If Samuel Alexander had gone off on his own accord why did Mark Alexander not contact the police to report the matter?

3 cards were sent, more than 3 months after the crime allegedly took place. It is deeply cynical to frame a friendly Christmas gesture as evidence of a cover up.Student jailed for 16 years for murdering father Sept 2010
“A law student who murdered his father in a bid to escape his "controlling influence" was jailed for life today with a minimum term of 16 years.
Mark Alexander, 22, killed 70-year-old Samuel at the family home before burying his body in concrete in the garden.
Passing sentence at Reading Crown Court, Judge John Reddihough said he accepted that Alexander may have been in fear of his father, but added that, after his death, he acted in a "despicable, callous and sometimes cunning manner".
Alexander remained impassive as he was taken down to the cells.
The partially-burned remains of the former lecturer were only found after neighbours became suspicious of his son and compiled a dossier of information for police.
The residents of Prospect Close, a cul-de-sac in the small village of Drayton Parslow, Buckinghamshire, were concerned they had not seen Egyptian-born Mr Alexander since a garden party in August 2009.
The victim's neighbours were praised in court today for building up a dossier of their concerns and going to the police.
Mr Alexander was eventually reported missing in February this year, five months after it is believed he was murdered.
Officers found his badly decomposed remains buried under mortar and concrete in the garden. His son had attempted to burn parts of the body in a bid to disguise its identity.
During the course of a six-week trial it emerged that Mark Alexander, who was studying law and French at King's College, London at the time, faked his father's signature in Christmas cards as part of a plan to conceal the murder.
