The son of a man who murdered his mum and buried her under the floorboards of their home says he will never forgive the killer who took his secrets to his grave.
Harry Jarvis hid his mistress Rita Heyster in his garden shed at his home in West Lothian, Scotland, before killing wife Carol and hiding her decaying body in the cellar.
Pastry heiress Heyster, who inherited and squandered a £2.5 million fortune, helped him to conceal the body at his home after the 2009 murder.
The cause of 47-year-old Carol Jarvis’ death was never able to be determined due to decomposition, and Jarvis claimed she died of a fit and that he had buried her at their home to be close to her.
He never spoke to his four children about their mother’s death and died of heart failure in prison aged 67 in 2017 after being convicted of murder.
Mum-of-four Carol, who had several medical problems, was reported missing by her children.
They didn’t believe their father’s account she had taken a trip to Dundee or gone into respite care.
Notes discovered by police revealed Jarvis planned to move Heyster into his home after he had killed his wife and in one he wrote: “Drugs are doing job. Just took longer than I thought but going fast now. See you in Paradise soon.”
In a new Crime+Investigation channel documentary Killer Britain, presented by Dermot Murnaghan, Jarvis’ son Graham said he could never forgive his father.
He said: “I don’t think I will ever forgive or forget dad for what he has done because there is no rhyme or reason to it.
“Even though we wanted to be civil and understanding there was the whole trial and the way he handled himself.
“If he had put his hands up and we knew what actually happened there’s potential you can not so much understand and accept it but you can process it more.
“Now there will always be that question of what actually happened and what got him to that stage. Nobody is going to know that and because of that I can never forgive him for it.
“The trial was the last time we saw dad, I don’t think any of us got in contact with him.
“When he died it was like it was closed off but then again it’s never really closed off.
“It still plays on your mind after 11 years, it’s still as fresh and it’s like it was yesterday.”
Former bus driver Jarvis was jailed for a minimum of 15 years in 2011 and died while serving his sentence at Addiewell prison.
Heyster, from Coldstream in the Borders, inherited a £2.5million fortune from her adopted father, Jus-Rol founder Tommy Forsyth.
But she fell on hard times and blew the cash before starting an affair with Jarvis. She was jailed for four-and-a-half years for helping to conceal Carol’s body.
In 2015, the pair planned to marry behind bars but just a month later Heyster called off the wedding.
In the documentary, Graham, 39, revealed he and Jarvis’ other children had some sympathy with Heyster.
He said: “All the siblings felt sorry for her to an extent. It probably could have been any woman and it fell on Rita.”
Killer Britain with Dermot Murnaghan will be shown on Crime+Investigation at 9pm on June 4.
