Killer admits stabbing Andrew Alexander 81 times
A killer stabbed his victim 81 times then went to play roulette after the attack, a court has heard.
Robert Mason admitted murdering Andrew Alexander, 56, in a frenzied assault at a flat in Dennistoun in January.
The High Court in Glasgow heard Mason had earlier bought a blade from a shop after claiming he was "sick" at the way he was being treated.
The 30-year-old, who has previous convictions for carrying a knife, will be sentenced in August.
The court heard the murder happened following a dispute over money.
The killer, who was described in court as a "Jekyll and Hyde character", had known Mr Alexander for a number of months prior to his death.
The 56 year-old had given Mason cash - believed to be around £30 - but had never been repaid.
Mr Alexander eventually put a note through his letterbox asking him to call.
Frenzied and violent
The court heard that on 28 January - the day of the murder - Mason told his partner Nicole Wright that he was "sick" at how he was being treated by Mr Alexander.
He later went to a shop in the city's Trongate and purchased a knife before meeting Mr Alexander at his home in Dennistoun.
Prosecutor Lesley Shand QC said Mr Alexander was set upon at his flat, suffering a total of 81 stab wounds.
A blood-stained Mason fled the property and was soon spotted going into a Ladbrokes bookmakers nearby to play roulette and other games machines.
The killer later ditched gloves, clothes and a watch worn during the attack.
Mr Alexander - who lived alone - was reported missing the next day by a friend.
His body was eventually discovered by police in his flat lying face down in a pool of blood.
The court was told the murder weapon was never recovered.
Mason was quizzed by police and initially claimed he had not seen Mr Alexander for days.
Mason's QC, Robert Anthony, said he accepted he was guilty of a "frenzied and violent attack".
He added: "There is very obvious remorse shown."
The advocate said Mason had described himself as "normally rather quiet" but could be a "Jekyll and Hyde character".
Judge Lord Turnbull adjourned sentencing until 19 August.
