A killer, who was snared by his distinctive Nike trainers after assaulting a man in Renfrewshire, has been jailed for nine years.

Dad of one Paul Mathieson died after being attacked by 36-year-old Jamie Anderson in Renfrew last January.

Anderson, from Paisley, was caught after a painstaking five-month investigation by detectives which included an appeal by Mr Mathieson's family.

Police examined hours of CCTV footage to piece together Mr Mathieson's last hours and interviewed everyone who was in contact with him.

These enquires produced a list of 22 suspects, including Anderson.

When police searched Anderson's home and examined the clothes and shoes he was wearing that night DNA was found on the stitching and welt of the right trainer.

The distinctive rear flash of the trainers was also captured on grainy CCTV of the killing.

At the High Court in Glasgow on Thursday, Anderson, admitted killing the 37-year-old dad-of-one by punching him on the head, causing him to fall to the ground and kicking and punching him on the head and neck at Houston Street, Renfrew, on January 14, 2018.

Mr Mathieson died from his injuries at the Queen Elizabeth Hospital two days later.

Anderson was originally charged with murder but prosecutor Jane Farquharson QC accepted his guilty plea to a reduced charge of culpable homicide.

CCTV played in court showed Mr Mathieson, who was carrying a pizza box, and his killer embracing and going their separate ways.

But, seconds later Mr Mathieson put down his pizza box and Anderson thought he was going to attack him.

Anderson knocked Mr Mathieson to the ground and then as he lay there helpless, kicked and punched him before walking off.

The court heard that at different times the two men had dated Gillian Carswell.

She contacted Mr Mathieson on Whatsapp at 1am the day before the incident saying: "Jamie's just left, he was saying to me u were telling him I was doing ur nut in always coming to your door n phoning n asking for money?

Defence QC John Scullion said: "The two men met for the first time a few days prior to this incident. It became clear they had both been involved in a relationship with Miss Carswell.

"She had a history of playing partners off against one another and there appears to have been an element of this.

"Mr Mathieson was annoyed at the accused for telling her about the conversation they had had, but they embraced and the incident appeared to be over."

However, as they went to go their separate ways, Mr Masthieson put his pizza down on the roof of a parked car and walked back towards Anderson.

Mr Scullion said: "Mr Mathieson shouted: 'You're getting snipered' which the accused thought meant he was going to be attacked and assaulted him."

The court heard the cause of Mr Mathieson's death was blunt force trauma to the head and neck.

Judge Lord Armstrong told Anderson: "The loss to Mr Mathieson's family will be severe and long-lasting."

Anderson showed no emotion as he was led away to begin his sentence.
