The mother of a charity worker who was strangled to death by her cannabis-addict boyfriend has slammed the justice system after he was handed an indefinite hospital order.

Kennedi Westcarr-Sabaroche, 25, was killed in her car by partner Gogoa Tape, 28, who then drove around with her lifeless body in the passenger seat.

However, prosecutors dropped a murder charged when Tape agreed to plead guilty to manslaughter by diminished responsibility, blaming his behaviour on mental health problems.

Ms Westcarr-Sabaroche's family say Tape got off lightly because his issues were exacerbated by own decision to keep using cannabis, despite warnings to stop.

Her mother Linda Westcarr said: 'The system has failed her, and failed us.'
