A BOURNEMOUTH man who killed and dismembered his father sent sexually explicit text messages to his dad about his partner while they were all staying in a caravan together, a court has heard today.

Nathan Robinson used a Stanley knife, hacksaw and a saw to cut up the body of his father, William Spiller, at the flat they shared in Lacey Court, Stedman Road, Southbourne.

The 28-year-old is on trial at Winchester Crown Court accused of the murder of the 48-year-old Poole taxi driver, which he denies, but admits manslaughter on grounds of diminished responsibility.

Glenys Molyneaux, who was the partner of Mr Spiller, told the court that for a period she had been living in a caravan and he would come to stay along with his son on occasion.

She said that one night when they “were all in bed in the middle of the night”, Mr Spiller showed her three sexually explicit text messages that Robinson had sent him.

Ms Molyneaux said: “Will received them. They were about me. They were sexually explicit, I was horrified.

“He was angry but it was clear from the text messages that it appeared that Nathan had been drinking when he sent them so Will made excuses for his behaviour.

“I got very upset about them being sent, I felt very uncomfortable and I wanted to go home so I got dressed and Will was driving me home but he persuaded me to come back.”

Ms Molyneaux said that Mr Spiller had become concerned about his son’s drinking.

She said: “He was quite worried because Nathan appeared to be drinking in the bedroom after he had gone to bed and when we found this out Will was quite concerned about it.”

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 note was found in their flat which showed that Robinson had borrowed £36,000 from him two years previously and after the killing, he had taken £7,500 in cash.

He said: “We suggest a dispute about money might be the cause, a trip to Scotland and money needed and a father who said no because that's what the defendant did do, go to Scotland with money from his father.”

Ms Molyneaux told the court that Mr Spiller did not use credit cards and tended to pay for things with cash and he had told her he had £150,000 in cash in a filing cabinet.

She also described how Mr Spiller would give his son money to pay for the insurance on his taxi and another car but Robinson had not done this leading to his father being stopped by police and ending up in court. He received an absolute discharge, the trial heard.

Mr Lickley told the court that Robinson had told police during questioning that he suffered from blackouts and amnesia and could not remember all of the incident in which his father died.

He said: “He said he had killed his father, he said he had blackouts and flashbacks from long-term post-traumatic stress disorder (PTSD).

“He said he was having flashbacks and remembers the Stanley knife, the junior hacksaw and tidying up and putting things in boxes.

“He remembers his father sitting on the bed, he remembers going for his dad and stabbing him. He said he was suffering from one of his episodes where ‘I kind of black out’.

“He said he had no reason to stab him because he loved him.”

Mr Lickley added: “He remembers picking up a part of his father and putting it in a large box. He remembers tidying up with the cleaner. He thought for some reason the rest of his dad went into the other boxes.”
