John O'Neil killed Raymond Gavin in jail laundry row
A prisoner has been sentenced after he admitted killing another inmate following a row over laundry.
John O'Neil, 27, punched Raymond Gavin at Kilmarnock Prison on 11 June 2014. The 52-year-old never recovered from the blow and later died in hospital.
The High Court in Glasgow heard that trouble flared in the jail's laundry room after Gavin "skipped the queue" by putting his bag before O'Neil's.
O'Neil was jailed for 28 months after admitting a culpable homicide charge.
The court heard that O'Neil lashed out at Gavin and punched him on the body.
The victim returned to his cell, but was later heard screaming.
A guard found him to be "sweaty and in obvious pain".
His condition deteriorated and Gavin went into cardiac arrest. He was later found to have significant bleeding in the spleen area.
Gavin died in Kilmarnock's Crosshouse Hospital on 27 June.
O'Neil, who has a history of violence, was identified as the culprit, and initially denied the attack before pleading guilty to culpable homicide.
