Man admits killing mother's lover in Balloch attack
A man has admitted beating a stranger to death after catching him in bed with his married mother.
Sean Mahan launched a 20-minute assault on Stewart McKellar after finding him naked in bed with his mother at the family home in Balloch while his father was working offshore in August.
He then phoned a friend and said: "I think I have killed him."
The 21 year old pleaded guilty to culpable homicide. Sentence was deferred at the High Court in Glasgow.
Mr McKellar, 33, was out with friends at the Lomond Park Hotel in Balloch on 23 August when he met Lavina Mahan.
Prosecutor Douglas Fairley QC said Mrs Mahan described being "chatted up" by Mr McKellar before she invited him back to her house on Luss Road for a drink just after 02:00.
The court heard that her son Sean then returned home and barged through the door, shouting: "How could you do this to my dad?"
He punched Mr McKellar repeatedly during a 20-minute attack, and also slapped his mother on the head.
Mahan then phoned a friend and said: "Mate, you will need to come down. This guy was sleeping with my mum and I think I have killed him."
Paramedics found "clear signs of a disturbance" at the house along with a hysterical Mrs Mahan.
Mahan was later found by police at a friend's house, hiding in a cupboard.
He was asked about Mr McKellar, and said: "I only punched him.
"What would you have done? My dad's working offshore and I come home to find my mum in bed with someone else."
Judge Lord Turnbull remanded Mahan in custody, deferring sentence to next month for reports.
