A ‘crazed’ man stabbed an innocent father to death in a frenzied attack over claims his girlfriend had been unfaithful.

Dean Williams struck Craig Essen after a fracas outside a bar in Mayfield, Midlothian.

Crazed Williams had stormed to the pub thinking his barmaid girlfriend had been unfaithful.

He attacked Mr Essen, 28, - who it turned out had nothing to do with the young woman.

Williams is behind bars after he admitted to a culpable homicide charge at the High Court in Glasgow.

A judge warned the 21 year-old - who sat with his head in hands throughout most of the hearing - that he faces a lengthy jail term next month.

The court was told how Williams had been dating 22 year-old Melissa Carr on and off for the last six years.

Williams heard Miss Carr had been flirting with another man while working as a barmaid at the Rowan Tree Pub in Mayfield.

Prosecutor Allan Nicol said: “It is understood he found out about the developing relationship between the two. This is almost certainly the catalyst for his (later) behaviour.”

Hours before the killing last November 24, Williams had been out at local bars with a friend before going to his mum’s home. He stayed there for a short time before going back out.

The court heard a drunken Williams then stormed off to the Rowantree Inn, where Miss Carr was working.

Mr Essen and his friends were also there that evening enjoying a night-out.

CCTV played in court showed Williams battering a glass window while armed with a knife.

Mr Nicol said a “hysterical” Miss tried to hide while contacting police.

Williams then rushed into the bar and started frantically stabbing at a fruit machine.

As revellers cowered, the pub DJ grabbed a cricket bat to try and get Williams out. Mr Essen and a number of his friends then stepped in to help.

Williams was forced outside into the car park - but he came back at the group with the blade.

He then tried to run off, but fell on the ground before a fight broke out.

Mr Nicol told the court that during this struggle, he lashed out with the knife striking Mr Essen in the chest.

CCTV showed Mr Essen staggering away back into the bar, where he collapsed.

The dad, of Dalkeith, Midlothian, was rushed to hospital - but died in the early hours.

It emerged Mr Essen - who left behind a young son - died due to a stab wound to the abdomen and chest. The court was told the killing has had a “profound impact” on Mr Essen’s family.

His mum and half-sister had flown from their home in Australia following the tragic death.

They were in court along with other friends and relatives. Many sobbed loudly as details of the killing were revealed.

Herbert Kerrigan QC, defending, said Williams was “extremely distressed” at what happened.

Mr Kerrigan added: “He is categoric and makes no suggestion that it was the deceased who was involved with his partner.

“He named another individual who he had suspicions about - but he said that person was not even present in the pub at the time.”

Lord Matthews adjourned sentencing for reports.

But, the judge told Williams: “You have heard the distress caused to the family of the deceased - who are also victims of this appalling crime.

“No doubt you will reflect on that in due course.”

Mr Essen’s family were too upset to comment after the hearing.
