Nancy Pexton appeared at Highbury Corner magistrates court charged with murdering Jennifer Abbott

A woman has appeared in court charged with murdering her 69-year-old sister who was found stabbed inside her north London home.

Nancy Pexton, also 69, appeared at Highbury Corner magistrates court on Friday charged with murdering Jennifer Abbott, also known as Sarah Steinberg, last Tuesday.

The Metropolitan police had previously said officers were investigating whether Abbott’s death was linked to a diamond-encrusted Rolex missing from her home.

It is understood Pexton and Abbott are sisters, and Pexton is nine months younger than Abbott.
