A man killed his 25-stone father then carefully dismembered his corpse and "packaged" the body parts in plastic storage boxes following an argument over money, a court has heard.
Nathan Robinson used a Stanley knife, hacksaw and a saw to cut up the body of his taxi driver father, William Spiller, at the flat they shared in Lacey Court, Stedman Road, Bournemouth, Dorset.
The 28-year-old is on trial at Winchester Crown Court accused of the murder of the 48-year-old taxi driver which he denies but admits manslaughter on grounds of diminished responsibility.
Nigel Lickley QC, prosecuting, told the jury that Robinson killed his father on May 16 2013 following an argument over money.
He said that a neighbour who lived below the pair noticed on the afternoon of that day a "pink liquid" was dripping through the ceiling of his bathroom.
The prosecutor said that this was diluted blood as Robinson cleaned up the crime scene with a floor and a steam cleaner which he went out to buy after he killed his father.
Mr Lickley said: "Mr Spiller was a large man, 6ft 5in, he weighed in excess of 25 stone in weight, hence I say when his body was cut up and dismembered, it would have taken time and effort. Armed with a Stanley knife, small hacksaw and a saw, it would have been a messy business."
He added that the body parts had been "packaged neatly" in the boxes.
The prosecutor said that Robinson attempted to cover up the killing and had created a "things to do" list including paying the rent on the property, which was his first action after the incident.
He also used his father's mobile phone in the following weeks in an attempt to pretend that he was still alive.
After paying the rental company at their offices in cash, he then went to a store and purchased the cleaning equipment.
The neighbour who spotted the dripping blood had previously heard an argument coming from their flat in which the deceased said: "Do you expect me to keep subsidising you for the rest of my life?"
When he went to investigate the liquid, the defendant answered the door and was described as "very calm, just normal, very collected, there was nothing to say he had just had a fight with his dad".
Mr Lickley said that Robinson's actions meant that his father's body was not found until a month later, on June 17, after his father's partner Glenys Molyneaux, reported him missing to police after he stopped replying to text messages.
She had believed he had been visiting a friend, Simon Green, in the West Midlands, who was seriously ill and who has since died.
He said: "Dorset Police attended the flat, they noted strong smells and flies, alive and dead, in the hallway leading up to the property.
"They entered and they found Mr Spiller within the bedroom area, his body had been dismembered, that is cut up, deliberately and carefully and placed in plastic storage boxes together with items of clothing.
"Mr Spiller's head had been removed, cut off, and was found within another box within a filing cabinet in the bedroom.
"In one of the boxes was a Stanley knife with a relatively small but sharp blade, a saw and a small hacksaw - the tools, the Crown say, which were used to kill and cut up the body of Mr Spiller."
Mr Lickley said that Robinson took at least £7,750 in cash belonging to his father and on May 22 went to visit friends in Glasgow where he spent up to £300 "drinking, eating and socialising", all the time sending text messages purporting to come from his dead father.
He then used more money stolen from his father to pay for a weekend with his mother, who was separated from the deceased, to stay at a hotel in Bristol for a vegan weekend.
When he was later arrested at his mother's home in Birmingham, Robinson said to police: "Is this a joke?"
