"The deaths of Zachary and Amon have compounded their grief and they have lost two entire
generations of their family to a violent and completely senseless act of murder at the hands of Simpson-Kent.
"Our efforts to bring Simpson-Kent back to the UK to face justice were greatly expedited by the help we received from the Ghanaian authorities and the National Crime Agency, who alongside us, ensured
Simpson-Kent was arrested as soon as possible and returned to the UK.
