Men who raped and murdered young father in Methil jailed for life

Mr Simpson was rendered unconscious by the combination of the tablets and alcohol.

Allan claimed Mr Simpson had been conscious and consenting when he was tied up by the pair, but acknowledged they had continued their attack after he “passed out”.

The pair filmed several videos of their assault on a mobile phone, which were later deleted but officers from Police Scotland’s specialist cybercrime unit were able to retrieve the footage.

During the earlier trial, Brister told the court: “I won’t dispute the fact that Calum passed out and we carried on. I didn’t spike that boy, but yes, I gave him drugs.

“We raped him and continued to have sex. It is what it is, disgusting. It should never have happened. I am not going to make excuses.”

Allan, meanwhile, said he was “disgusted” that the videos were taken, but said he “did not know he was doing something wrong” at the time.

After their attack, the pair left Mr Simpson unconscious before going to sleep. In the morning they found him cold and rigid.

However, before contacting the emergency services, the pair first concealed what remained of their drugs in a safe and handed it to a neighbour.

Ambulance personnel were called at 12:03 and confirmed Mr Simpson had died.
