In a victim impact statement read at the sentencing, PC Harper's wife, Lissie, said: "So not only did these men take my true, beautiful love away from me, not only did they rob a brother, son, uncle and friend from all who love him, but they took our future too.
"They took more than one life away that day, they stole the person that I used to be, the happiness that we shared and the beautiful plans we had made together.
"That night as I opened the door to the stranger in uniform before me, everything I had known in my life to be true was robbed away. Every ounce of beautiful peace, gone."
Speaking after the sentencing, Detective Superintendent Stuart Blaik said he believes the three people responsible for the death of PC Harper never showed genuine remorse for their actions.
Paying tribute to PC Harper and his family, he said: "I would again like to pay tribute to the incredible courage and dignity shown by Andrew’s family, who have experienced such trauma and heartache over the past 11 months.
"They have faced two high profile trials and have had to endure hearing the most horrific detail about Andrew’s death played out in public. I can never thank them enough for their bravery and for their support."
