Laura McArthur was getting ready for a shopping trip with her daughter when she found out she had died in her sleep.

At 16, Jodie Muir passed away "painlessly" with a smile on her face the morning after spending a Friday night with her friends at a party in Rutherglen.

"She must have been having a good dream", Laura said.

But contrary to her peaceful passing, circumstances surrounding Jodie's death were calamitous.

Her name appeared in media headlines in 2014 after police issued a statement saying " she may have taken some form of ecstasy type drug" - but her post-mortem was inconclusive and a further toxicology report was clean.

Jodie had phoned her mother at various points during the evening - ending calls with "love you". She had one unit of alcohol in her system.

It is thought Jodie suffered "sudden death", an occurrence associated with an underlying heart condition which both Jodie's mother and sister Taylor were diagnosed with - Long QT syndrome (LQTS).

Now Laura is working to provide hundreds of free heart screenings for young people in the west of Scotland.

As well as running a catering business, Laura has spent the past two years fundraising for the Jodie Muir Memorial Trust, which funds free heart tests through the Cardiac Risk in the Young (CRY) charity.

Almost 200 people received screenings at Eastbank Academy in Shettleston on Tuesday, a procedure which can cost £45 for a young person.

CRY offer free screenings for young people age 14 to 35 across the UK, where a small percentage will be found to have heart abnormalities. Patients are then referred to a specialist in London.

The work aims to reduce the 12 young people who die suddenly every week in the UK from undetected heart conditions.

"Jodie was loved by everyone," said Laura. "She didn't see any badness in people, she always saw the good, and she just laughed all the time.

"She was fit and healthy, always climbing trees and jumping off walls. She wasn't perfect - we had our arguments and she used to say I was too strict.

"But she was brilliant and what happened to her was really sad."

With hopes to raise £10,000 each year for further screenings, Laura says she hopes to target deprived areas in Glasgow first.

Alongside CRY she has organised tests in four schools, which will be open to people within the age range who wish to book an appointment.

Laura said: "It's a decent amount and it benefits the schools in the east end. No one knows what is going on with these underlying heart conditions and they're evolving every day.

"I didn't expect that would happen to Jodie. The police completely dismissed me, they didn't care. I fought endlessly and hard with them.

"You think of the risk of heart disease in areas like this - diets are a problem, there's high rates of alcoholism, drugs users and I just think let them see that there's potentially something wrong.

"I'm so proud to do this in Jodie's name because I know her death hasn't been in vain. Her death is helping people. If I can help one person I'm happy."

Families flocked to the free service in the east end of Glasgow from as far as Moray. Kiara Henderson from Kilwinning is one patient who will receive help after having her heart screened.

The 20-year-old has experienced blackouts followed by seizures for almost two years and has yet to be diagnosed.

She said: "It's been getting worse - I get these seizures a couple of days a week, sometimes a couple of times in a day. At most I had 36 episodes in five weeks.

"My mum Georgie gave up her shop to look after me. Today I've had more help than I've ever had with the NHS."
