Sister found guilty of killing film director sibling and taking her Rolex watch

A woman has been found guilty of killing her film director sister and stealing her diamond-encrusted gold Rolex watch.

Nancy Pexton, 70, slashed and stabbed Jennifer Abbott 10 times at her flat in Camden, north London, on 10 June 2025.

The 69-year-old had gaffer tape on her mouth when a concerned neighbour broke down her door three days later.

Her sister was arrested on 18 June, with jurors hearing how the Rolex was found in her bag after she was admitted to hospital.

The court previously heard how Pexton had told her sister she was "planning to kill" her months beforehand, leaving her considering a restraining order.

She had warned Ms Abbott to "watch your back" and accused her of betraying her in "every way because you [were] jealous of me".

Examination of Pexton's phone revealed a series of notes in which she referred to thinking about killing her sister and complained about other family members.

Ms Abbott, a US citizen, was last seen alive on a doorbell camera at 7.36am on the day of her death after returning from walking her corgi.

Her sister spoke to her on the phone at 11.36am and took the bus to her Mornington Place flat at 12.45pm, leaving an hour later.

She called her GP and said she'd taken an overdose and was taken to hospital, where she stayed until her arrest a week later.

The fate of her sister was revealed on 13 June when her neighbour, concerned by her dog's barking, used a scaffolding pole to break in.

The trial heard Ms Abbott was found with a gaping "slash-type" wound across her neck and tape covering her mouth.

A post-mortem found she suffered multiple slash and stab wounds and single defensive wound on her hand.

He gold Rolex, a gift from her son Brad Carlson which she never removed, was missing.

Mr Carlson told the court via videlink: "There was interaction and sometimes anger and hostility between my mother and Nancy, there was resentment seemingly bubbling up."

Jurors also hears Ms Abbott had revealed concerns to her nephew, telling him Pexton "was capable of anything" and asking whether she should get a restraining order.

In November 2024, she shared a message in which Pexton told her: "You know I was planning to kill you but it was just a thought, I would never hurt you.

It also warned her to "watch your back from those you conned and stole money from".

Pexton added: "You never know they could get you while you walking your dog. Be careful honey, I worry about you. You so many enemy (sic)."

More evidence of her evil intent was found in a phone note in which she referred to potentially killing her sister and complained about other relatives.

She told police she was just "venting" feelings and actually loved her sister. She also claimed to have no memory of the 90 minutes spent in the flat.
