Penny Jackson made a sick April Fool’s joke about her husband being locked down and hanging him – months before she murdered him on her 66th Birthday.

The wealthy retired accountant killed her husband David, age 78. She calmly said to police, “I should have stabbed his more,” as he died on February 13. 

Today Jackson revealed that Jackson made Jackson’s Facebook cover photo of a woman knitting an apron on April 1, 2013. This was ten months after she murdered her husband.

A caption above the image read: ‘‘Quarantined with hubbie for two weeks – Gertrude is knitting something special for him!’ 

Jackson was this week found guilty of murder by a jury of eight women and four men after 10 hours and 43 minutes of deliberations. Judge Martin Picton sentenced her life imprisonment with a minimum term for 18 years.  

Today Penelope Jackson published a Facebook cover photo of a woman knitting a knot on April 1, 2013. This was just ten years before she killed her husband.

Jackson was arrested in her pyjamas on the street outside the couple’s £450,000 luxury Somerset bungalow while her fourth husband lay bleeding on the kitchen floor inside.

As she was taken into custody, Jackson said: ‘Do you usually have murderers where they’re wearing Marks & Spencer pyjamas?’ 

The former Ministry of Defence accountant said she was unable to control herself after years of verbal and physical abuse. She claimed that Retired Lieutenant Colonel David Jackson was a bully and pushed her to the limit until she could no longer take it. 

According to some reports, Jackson’s happy marriage was plagued by lies and infidelity.

Friends told the Daily Mail that both sides were to blame for the row over the slightest thing. 

Despite Jackson’s attempt at portraying herself as a victim, Jackson was actually a mother-of-three who left three marriages before she married Jackson.

One of her brothers-in law said that Penny, given the way she’s treated three other husbands, was not someone who would abuse over the years. 

Stewart Warrender, Penny’s brother and third husband, said that Penny was narcissistic. No empathy. To be like that, there must be something wrong with someone.  

Jane Calverley, David’s first married daughter, said Penny was more than her husband and that she would bait him’.

She said that he would squirm and look embarrassed if we were out with company.

Veronica Statham, a friend of Penny, said that she could become quite overwhelming after a few beverages.

Alan Jackson, David’s brother, told the Mail this Week that he was a bully and an ‘arrogant bully’. Penny also said that he learned to not answer back when there was a dispute brewing and they had been drinking.

Jackson’s daughter told Jackson that Jackson could get ‘too loud’ and get carried away.

Jackson married Melvyn Porter, a Weston-super-Mare builder, in November 1972 at the age of 17. Their first daughter, Rebecca was born a year later. Victoria was born in 1977. Jackson left the family when the youngest was only two years old. 

In April 1981, Jackson, then 26, married Tony Rothwell (a fellow Ministry of Defence civil servant). She claimed in court that their “loving friendship” had ‘fizzled out and they divorced.  

Jackson was 32 when Jackson married her third husband in January 1988, 39-year old Alan Warrender, an RAF chief technician. His first wife, Penny, had died from cancer 18 months prior. She became stepma to Alan’s daughters after Penny passed away.

In October 1990, Isabelle, her third daughter, was born to her. By then, the family was still living in Grantham in Lincolnshire.

The final, fatal blow was delivered after he had dialled 999, with the emergency services still on the line. When police arrived, they found Jackson’s handwritten confession (pictured)

The final blow came after Jackson had dialled 911, with emergency services still on the phone. Jackson’s handwritten confession (pictured), was discovered by police upon his arrival.

Two years later, Penny began an affair while Penny was in Saudi Arabia with Alan, a 43-year-old man. He would later become her fourth husband. His inquest into his death, which revealed that he had died from carbon monoxide poisoning in April 1993, was published under the headline: “Man took his life after marital stress”.

He was found in the garage. Stewart Warrender, Stewart Warrender’s brother, stated that he was apparently drunk and emotional because his sister had been having an affair. ‘I was never completely satisfied with the inquest verdict. I was skeptical about a suicide. It could have been more coercion. I strongly believe that it was not properly investigated. That is what I have believed all my life.

He said that the family was feeling ill because Penny had ‘benefited tremendously’ from Alan’s passing. “Alan’s children from his first marriage didn’t get a bean. Penny inherited everything, and was entitled to his retirement pension.

Jackson and David married in 1996, by which time they were living near an army base in Hampshire and raising Penny’s youngest daughter, Isabelle, to believe that David was her real father. She didn’t find out the truth until she was a teenager when one of her half-sisters from Alan Warrender contacted her.

Two years after Penny and David were married, David’s son Gavin, a 28-year-old from his first marriage, committed suicide. He left a suicide note in his will, in which he wrote that he didn’t want to be like his father. 

Jackson alleged that David became aggressive following Gavin’s suicide. Isabelle, her daughter, agreed and said that David had held a knife to her mother’s throat when she was eight. 

He once pinned Isabelle’s mother against the wall. Alan Jackson, David’s brother, told the Mail he could be an arrogant bully.

He said, “No one deserves to die like he did.” However, he could believe that Penny would have been pushed beyond her limits. I don’t believe anyone will ever truly know the kind of life she shared with David.
