The killer said he was “sick” at what had happened.

Detective Chief Inspector Martin Fergus from Police Scotland’s Major Investigations Team (WEST) said: “This was an extremely disturbing case which saw a man murdered and then disposed of in the most brutal of ways.

“David Collins is a very dangerous and callous individual and it is a relief that he has been taken out of our community, and will no longer be free to harm others.

“The trial has been a distressing time for the family of Kevin Bishop, who have had to sit and listen to the gruesome details of how their loved one died. I would like to thank them for the support they gave the inquiry team throughout this process and I hope that today’s outcome provides them with some sort of comfort.

“He was last seen by his family on Saturday, July 28 in the Ferguslie Park area of Paisley.  They reported him missing to police on Saturday, August 4.

“Kevin’s remains have not been fully recovered and it is vital that we find them in order to allow his family to grieve properly.

“I am appealing directly to anyone who may have knowledge of where his remains may be, to pass this information to Police Scotland’s Major Investigations Team (WEST) via 101.”

Lady Rae ordered Collins serve a minimum 26 years for the murder and attempting to defeat the ends of justice.
