Relatives of two cousins who were killed at a teenager's wake have spoken of their heartache.

Khailey McKenzie and Lynsey Berry also hope to use the tragedy to raise awareness of the devastation caused by knife crime.

Last week a jury found Robert Stratton guilty of murdering Julie McCash, 43, in Dumlanrig Drive, Dundee on February 26.

But after a trial at the High Court in Edinburgh he was only found guilty of the lesser charge of culpable homicide regarding David Sorrie, 32.

Stratton was jailed for life and ordered to spend a minimum of 23 years in jail.

Speaking exclusively to STV News, Khailey recalled the tragic events of February 26.

She said: "I was getting told my Mum had died when I had just left her sitting on the sofa.

"I got home and, ten minutes later, she had been killed."

Lynsey added: "And then about the back of 10 my world collapsed as well and I was told that David had passed away."

Both woman denied the wake was a "big drink and drug fuelled party".

Khailey said: "They were there grieving, they were comforting.

"They were just not that type of people.

"My mum would be the peacemaker out of everyone. She would be wanting to help everybody just be out to help people."

Khailey also expressed concern about how the case has affected her daughter, who she said suffers from "night terrors."

She added: "I told her to go out and play in the street and she said 'No. Someone might kill me in the street'.

"I did not know she had heard anything like that. Even to hear that my little girl is scared is horrible."

Julie and David were attending a vigil for Ralphie Smith, 18, just hours after he fell from cliffs at Arbroath.

The tragic teenager's body was found a month later.

The trial heard that Stratton - who had a previous conviction for attempted murder - took two knives from his kitchen after he and his partner were asked to leave the wake.

In the disturbance that followed Julie and David died from stab wounds.

Now the loved ones they have left behind want more to be done to combat knife crime.

Lynsey said: "You are never going to be able to get rid of knives, they are an everyday household item.

"But if you can make awareness of it and show the effects that it has on people then it's a start."

Khailey added: "All it takes is one stabbing and that's it.

"A mum and dad are not going home to their kids."
