Penelope Jackson, 66, killed David Jackson, 78, when he “kicked off” during a Zoom call with her daughter and son-in-law at her birthday party.

After the deadly attack, the retired accountant told an emergency call handler she had tried to stab him through the heart but that “he doesn’t have one”.

Jackson was jailed for life with a minimum of 18 years in October 2021 after being convicted of murder, The Sun reports.

The chilling case is now being explored in documentary Bubble and Squeak Murder: The Killing Of David Jackson on Crime and Investigation.

David’s brother tells the show he was on his killer sister-in-law’s side when the gruesome details of the killing in February 2020 emerged.

“I was watching the telly and all of a sudden, there was Penny being arrested for murdering my brother,” Alan Jackson said.

“I was glad, he deserved it.”

But not everyone in the show is sympathetic towards Jackson, who was slammed by a judge for showing “not a shred of remorse”.

Stewart Warrender, whose brother Alan married the killer in 1988, accused Jackson of being “narcissistic”.

Alan Warrender later took his own life after finding out she was cheating on him with retired lieutenant colonel David.

“She could have coerced him into going down that path, emotionally,” Mr Warrender said.

“I think she was clever enough to wind him up that way, to get rid of him and then carry on with this bloke that she’d already been seeing.”

He also accused four-times wed Jackson of showing no emotion at Alan’s funeral.

“Penny was so blasé. Your husband just killed himself. The father of your child has just killed himself. Are you not really bothered?” Mr Warrender said.

During her trial, Jackson said her marriage had “just imploded” and the years of her “putting up with the violence, the unwanted sex, the belittling, stopping me doing things, all the horrible things” had been for nothing.

She told jurors a row over her birthday dinner while on Zoom had been the “final straw” as Jackson had always hid his 20-year abuse from her daughter.

David had been angry because she had made bubble and squeak – a British dish made from cooked cabbage and potatoes that’s later mixed and fried – alongside the lobster, crab and steak meal they had.

Jackson “lost control” and first knifed her husband in the bedroom before stabbing him again in the kitchen.

She then wrote a confession note claiming she had “taken so much abuse over the years – look at my records.”

“But he was a good Daddy. However, the mask slipped tonight. That was unforgivable. I accept my punishment, may he rot in hell.”

Jackson later told emergency operators she had put “three holes in him,” she said.

“I’ve killed my husband, or tried to because I’ve had enough. I might go and stab him again.

“I am in the lounge, he is in the kitchen bleeding to death with any luck.”

Jackson then described her husband of 24 years as “getting a bit slumpy” during the chilling 18-minute call.

“I know this is being recorded. I am compos mentis, but I have had enough of the abuse and the nastiness. I am not doing anything to help him,” she said.

“He deserves everything he has got – I accept everything that is coming my way. I might just go and do it again.”

After she was arrested, bodycam footage showed her branding her husband a “bully” and saying “I’m glad I’ve done it” as he lay bleeding to death in the kitchen.

When she heard police calling for CPR, Jackson cried out: “Oh, don’t! No, no, please don’t. Ooh, I should have stabbed him a bit more.”

Jackson, who was wearing her Marks & Spencer pyjamas, also calmly asked officers if she could go back to the house to get her coat.

Alan said when he first saw the bodycam footage, he thought: “Listen, fellas, what she’s trying to say is the truth”.

But retired Metropolitan Police officer DCI Paul Settle has a different opinion of the harrowing arrest footage.

He tells the documentary: “It’s kind of a thing you’d associate with Colombian drug cartels, not with middle England.

“She shows absolutely no contrition, no remorse. We were all gobsmacked. On a different day that could have been our mum or our grandma.

“That’s the lady in front of you in the queue in the supermarket you pass the basket to. And now, flip of a switch, she’s a homicidal maniac.”
