A killer brutally murdered a teenage boy - then sent a sick video to friends boasting what he had done.
Kevin Murray turned on Kirk Allan, 19, at the thug's flat in Helensburgh, Argyll and Bute in the early hours of July 25, 2020.
The 34 year-old struck Kirk with a meat cleaver, choked him, bound and blind-folded the victim as well as zapping him in the face with pepper spray.
