Overview

• Stephen Alderton, 67, was sentenced to life in prison with a minimum term of 25 years for the murders of his daughter's ex-partner Joshua Dunmore, 32, and his father Gary, 57, following a family court dispute about moving his grandson to the US.
• Alderton was arrested after the crime by armed police on the M5 near Worcester, and his arrest was caught on camera by BBC.
• Before the murders, Alderton had expressed in text messages his intention to 'override any court decision', indicating a premeditated act.
• The victims were found dead at their separate homes in Cambridgeshire villages six miles apart, with the murders occurring two days after a family court hearing.
• In a letter, Alderton expressed regret for his actions, claiming he was 'not the person that this conflict and the family courts have driven me to become'.
