Kent woman wins Sheerness murder conviction appeal

A Kent woman jailed for life for stabbing her boyfriend in 2006 has won her appeal against a murder conviction.

Kirsty Scamp, from Sheerness, was 19 when she killed Jason Bull, 28, with a single wound using a kitchen knife.

On Wednesday, the Court of Appeal ruled the trial judge had given a flawed summing-up to the Maidstone Crown Court jury on the issue of provocation.

The judges imposed a six-year sentence for manslaughter, entitling Scamp, now 24, to be released immediately.

During her trial, the court was told Scamp flew into a rage when she heard Mr Bull talking to a woman on his mobile phone.

Mr Bull, a carer, of Sheerness High Street, died at the entrance to their flat shortly after being stabbed on 13 March 2006.
